General The REL511 line distance protection termi-nal is one of the basic units for distribution and sub-transmission line distance protection applications and forms a part of a PAN-ORAMA Station Automation. The PAN-ORAMA Station Automation concept includes a complete range of single-function
units and multi-functional terminals, Substa-tion Monitoring System (SMS) and Substa-tion Control System (SCS). The units in the PANORAMA concept are available as stand alone relays/terminals or as building blocks in a total power network management system.
Functions Line impedance
Distance protection (ZM1–5)
ApplicationDistance protection provides fast and reliable protection for overhead lines and power cables in all kinds of power networks. For each independent distance protection zone, full scheme design provides continuous mea-surement of impedance separately in three independent phase-phase measuring loops as well as in three independent phase-earth mea-suring loops.
Phase-earth distance protection serves as basic earth-fault protection in networks with directly or low-impedance earthed networks. Together with an independent phase-prefer-ence-logic, it also serves as selective protec-tion function at cross-country faults in isolated or resonantly earthed networks.
Independent reactive reach setting for phase-phase and for phase-earth measurement secures high selectivity in networks with dif-ferent protective relays used for short-circuit and earth-fault protection.
Fig. 1 Schematic presentation of the operate characteristic for one distance protection zone in forward direction
The distance protection zones can operate, independently of the others, in directional (forward or reverse) or non-directional mode. This makes it suitable, together with different communication schemes, for the protection of power lines and cables in complex network configurations, such as double-circuit, parallel lines, multiterminal lines, etc. Zone one, two and three has a built-in option for a phase selective operation.

The additional distance protection zones four and five have the same basic functionality as zone 1–3, except phase-selective output sig-nals.
DesignDifferent digital signal processors calculate the impedance as seen for different measuring loops in different distance protection zones. The results are updated each millisecond for all measuring loops and each distance protec-tion zone separately. Measurement of the impedance for each fault follows the differen-tial equation, which considers a complete line replica impedance, as presented schemati-cally on Fig. 2.
Fig. 2 Schematic presentation of the impedance measuring principle.
Setting of all line parameters, such as positive sequence resistance and reactance as well as zero-sequence resistance and reactance, together with expected fault resistance for phase-phase and phase-earth faults, are inde-pendent for each zone. The operate character-istic is thus automatically adjusted to the line
characteristic angle. The earth-return com-pensation factor for the earth-fault distance protection is calculated automatically by the terminal itself.
Voltage polarisation for directional measure-ment uses continuous calculation and updat-ing of the positive sequence voltage for each measuring loop separately. This secures cor-rect directionality of the protection on differ-ent evolving faults within the complex network configurations. Positive-sequence memory voltage secures reliable directional operation on close-up three-phase faults.
The distance protection function blocks are independent of each other for each zone. Each function block comprises a number of different functional inputs and outputs, which are freely configurable to different external functions, logic gates, timers and binary inputs and outputs. This makes it possible to influence the operation of the complete mea-suring zone or only its trip function by the operation of the fuse-failure function, the power-swing-detection function, etc.
General fault criteria (GFC)
ApplicationThe general fault criteria is an independent impedance measuring function, which serves as an overall fault detection and/or phase selection element in all kinds of networks. Observe that the GFCn function is not used as start function, because full scheme measure-ment is utilised for the distance protection zones.
The GFC function is specially suitable in cases when the fault resistance to be detected exceeds the minimum expected load imped-ance. The shaped operate characteristic in the impedance plane (see Fig. 3) prevents the operation of the impedance measuring ele-ments for low load impedances and at the same time allows coverage of higher fault resistance with remote infeed of the fault current.

Fig. 3 General fault criteria - schematic presen-tation of the operate characteristic in the impedance plane
Independent measurement for each fault loop secures reliable phase selection and correct operation for complex network faults, such as simultaneous faults on parallel circuits, evolving faults, etc. It also serves, together with an independent phase-preference-logic, as a selective protection function on cross-country faults in isolated or high-impedance earthed networks.Independent reactive reach setting for phase-phase and for phase-earth measurement secures high selectivity in net-works with different protective relays used for short-circuit and earth-fault protection.
DesignThe basic operate principle is the same as for the basic distance protection zones (see Fig. 2). It is possible to set the reactive reach in forward and reverse direction for phase-phase and for phase-earth measurement separately and independently of each other. Setting of the resistive reach can also be different for phase-phase and for phase-earth measure-ment.
The user can program the influence of the GFC function on the operation of the distance protection zones used. The GFC function can prevent the operation of the distance protec-tion zones with a reach longer than the reach
of the GFC elements, as long as the measured impedance is outside the GFC operate charac-teristic.
Operation of the distance protection zones can also be completely independent on the operation of the GFC function.
Power swing detection (PSD)
ApplicationThe power swing detection function detects power swings with a periodic swing time as low as 200 ms (i.e. slip frequency as high as 10% of the rated frequency on a 50 Hz basis). It detects swings under normal system condi-tions as well as during the dead-time of the single-pole reclosing cycle.
DesignThe operation of the PSD function is based on the measurement of the transition time that the power swing transient impedance needs to pass the impedance area between two imped-ance measuring characteristics (known as ∆Z/∆t measurement). The impedance measuring principle is the same as the one used for the distance protection zones (see Fig. 2). The transient impedance time is measured in all three phases separately and one-out-of-three or two-out-of-three operating modes can be selected permanently or according to the spe-cific system operate conditions.
The use of different timers for initial and con-secutive swings secures a high degree of dif-ferentiation between power swing and fault conditions. Built-in logic circuits and config-urable functional inputs makes it possible to combine the function with other functions and conditions, as well as to use it in the same way as with older distance relays.
Scheme communication logic (ZCOM)
ApplicationTo achieve fast fault clearing for a fault on the part of the line not covered by the instanta-neous zone 1, the stepped distance protection function can be supported with logic, utilising communication channels. One communica-tion channel, capable of transmitting an on/off signal, is required in each direction.

Depending on whether a reverse or forward directed impedance zone is used to issue the send signal, the communication schemes are divided in ‘Blocking’ and ‘Permissive’ schemes, respectively. This function can support any scheme communication require-ments.
Current reversal and weak end infeed logics (ZCAL)
ApplicationThis function is a complement to the ZCOM or to the ZC1P function.
In interconnected systems, the fault current can change direction when circuit breakers open to clear the fault. The permissive over-reach scheme should have a current reversal logic which, when activated, will prevent unwanted operation in case of current rever-sal.
If the infeed of the fault current at the remote end is too low to operate the forward directed measuring element, no carrier signal will be obtained from the remote end when there is a fault on the line and the communication scheme will not operate properly. This will be the case if the zero sequence source at the remote line end is too high, e.g. if the line cir-cuit breaker is open. The permissive commu-nication scheme should therefore include a weak end infeed logic which, when activated, reflects the carrier signal and thereby secures tripping. It can also be used to trip the local circuit breaker in cases when fault current distribution prevent carrier signal.
Automatic switch onto fault logic (SOTF)
ApplicationThe switch-onto-fault protection secures high-speed operation of the distance protec-tion on energising of faulty or short-circuited (earthed for safety reasons) power lines. Two operating modes are available for the detection of a breaker closing condition: Use of an auxiliary contact from a line CB control switch or the operation of a built-in dead-line-detection (DLD) function. The sec-ond mode is highly recommended for busbar
configurations where more than one circuit breaker can energise the protected line at one line end.
DesignThe function is active for one second after the breaker closing conditions have been reported by the external auxiliary contact or by the DLD function (automatic mode). The output signal will be generated if the fault has been detected within the non-directional reach of the selected distance protection zone. Config-urable function inputs and outputs make it possible to configure different use of the function. Note: The presence of the dead-line-detection function is absolutely required, if the function shall operate in the automatic mode.
Local acceleration logic (ZCLC)
ApplicationTo achieve fast fault clearing for faults on the whole line, also in cases where no communi-cation channel is available, local acceleration logic is used. The logic can be controlled either by the autorecloser or by the loss of the load current.
Current, phase wise
Instantaneous phase over-current protection (IOC)
ApplicationDifferent system conditions, such as source impedance and the position of the faults on long transmission lines, influence the fault currents to a great extent. The IOC function, with low overreaching of the measuring ele-ments, secure very short operate times, down to 10 ms and selective tripping for close-in faults on long power lines, where short fault clearing times are extremely important in maintaining system stability
DesignThe IOC function comprises a three phase instantaneous overcurrent protection. When single-pole tripping is required, the single and/or three-pole trip logic allows for phase selective starting signals from the function.

Functions (cont’d)Functions (cont’d) Time delayed phase over-current protection (TOC)
ApplicationThe time-delayed overcurrent protection operates in different system conditions for currents exceeding the pre-set value and remain high for longer than the delay time set on the corresponding timer. The function can also be used as supervision and fault detector for some other protection functions, to increase the security of a complete protection system. It can serve as a reserve function for the line distance protection, if activated under fuse failure conditions which disables the operation of the line distance protection.
DesignThe TOC function comprises a three phase time-delayed overcurrent protection. Phase selective starting signals are available from the function.
Breaker failure protection (BFP)
ApplicationThe breaker failure protection provides back-up protection in case of failure of the breaker to trip and clear the fault as requested by the object protection. It is obtained by checking that fault current persists after a brief time from the operation of the object protection.
DesignThe breaker failure protection is initiated by the trip commands from the protection func-tions, either internal to the terminal or from external commands through binary inputs. The start can be single-phase or three-phase.
The operate values of the three current mea-suring elements are settable within a wide setting range. The measurement is stabilised against the dc-transient that can cause unwanted operation with saturated current transformers. Time measurement is individ-ual for each phase. Two independent timers are available, T1 for repeated tripping of ‘own’ breaker and T2 which operates trip logic for adjacent breakers.
Current, residual (earth fault)
Current residual
ApplicationIn case of single-phase to earth faults, the primary fault resistance will vary with the network conditions and location of the fault. In many cases the fault resistance is much higher than the resistance that can be covered by an impedance measuring distance func-tion.
Earth faults with high fault resistance can be detected by measuring the residual current (3Io). Hence, the current residual functions can be used as complement to the impedance measuring distance function for sensitive earth fault detection.
To prevent unwanted operation when energis-ing a directly grounded power transformer, the functions are provided with 2nd harmonic restraint blocking feature.
The inverse time delayed function is provided with minimum operate current and minimum operate time for improved selectivity in cer-tain applications.
The instantaneous and time-delayed functions can be made directional together with logics for communication scheme cooperation, weak-end-infeed and current reversal.
DesignFollowing current residual functions are selectable;
1. Instantaneous
2. Time delayed;
- Independent time delay
3. Inverse time delayed;
- Normal inverse (NI)
- Very inverse (VI)
- Extremely inverse (EI)
- Logarithmic inverse (IDG)

5. 4-Step earth fault protection (4 ele-ments)

Page 7
The 4-step earth fault overcurrent protection has three current steps with independent time delay and a fourth current step with indepen-dent time delay or inverse time characteris-tics.
For all four steps, one of the following modes can be selected independently of other steps:
• Non-directional overcurrent function with-out second harmonic restraint
• Non-directional overcurrent function with second harmonic restraint
• Forward directional overcurrent function without second harmonic restraint
• Forward directional overcurrent function with second harmonic restraint
• Overcurrent function without second har-monic restraint, with blocking from the reverse direction measuring element
• Overcurrent function with second har-monic restraint, with blocking from the reverse direction measuring element
Voltage
Time delayed undervoltage protection (TUV)
ApplicationThe time-delayed undervoltage protection function is applicable in all situations, where reliable detection of low phase voltages is necessary. The function can also be used as a supervision and fault detection function for some other protection functions, to increase the security of a complete protection system.
DesignThe function operates as a three-phase volt-age measuring function, which issues an out-put signal if any of the three measured phase voltages falls below the pre-set value. The operation can be delayed by a built-in timer with settable time delay. The function can be disabled by various external conditions, for example by the operation of a fuse-failure
function or by an auxiliary contact detecting the open position of a line isolator. The func-tion has phase-selective indication.
Time delayed overvoltage protection (TOV)
ApplicationDifferent system conditions might increase the system voltage and cause damage to exposed primary and secondary equipment. The overvoltage protection detects such volt-age changes and initiates different measures to the power system. Both instantaneous and time-delayed operation of the overvoltage function are available.
DesignThe function measures the phase voltages of a three-phase system and calculates the residual (3U0) voltage. It initiates the corresponding output signals if the measured phase or the residual voltages exceed the pre-set value (starting) and remains high longer than the time delay set on the corresponding timers (trip). The function detects the phases which caused the operation.
Power system supervision
Broken conductor check (BRC)
ApplicationThe broken-conductor check function detects non-symmetrical current conditions in the three phases. The BRC function is especially suitable for the detection of broken conduc-tors on protected power lines and cables (series faults) without the presence of the additional short circuits (phase-earth or phase-phase faults). It will also detect inter-ruptions in secondary current circuits.
DesignThe function measures all three-phase cur-rents and operates when the ratio between the minimum of measured phase currents and the maximum phase current falls below the set value. The phase current must be higher than 20% of the terminal rated current.

Page 8
Functions (cont’d)Functions (cont’d) Loss of voltage check (LOV)
ApplicationThe loss-of-voltage function is suitable for use in networks with automatic restoration function. The LOV function initiates a three-pole tripping of a circuit breaker, if all three phase voltages fall below the set value for longer than 7 seconds. The operation of the function is supervised by the fuse-failure function and the information about the closed position of an associated circuit breaker.
Overload supervision (OVLD)
ApplicationThe overload protection prevents excessive loading of power lines. Its operation is based on the measurement of the maximum phase current and its duration, which must not exceed the pre-set values. The operate current and the operate time are settable within a wide range.
Secondary system supervision
Current circuit supervision (CTSU)
ApplicationWrong information on current flowing in a protected element might influence the security (line differential protection) or dependability (line distance protection) of a complete protection system. The current cir-cuit supervision function, as built in REx 5xx terminals, detects different types of faults in CT secondary circuits and influence the oper-ation of corresponding main protection func-tions.
DesignThe function compares the 3I0 secondary currents from two different sets of current instrument transformers or different cores of the same instrument transformer. The func-tion issues an output signal when the differ-ence is greater than set value. The signal can be configured to block different protection functions or initiate the alarm.
Fuse failure supervision (FUSE)
ApplicationThe fuse-failure-supervision function contin-uously supervises the ac voltage measuring circuits between the voltage transformers and
the terminal. Different output signals can be used to block, in the case of faults in the ac voltage secondary circuits, the operation of the distance protection and other voltage-dependent functions, such as the synchro-check function, the undervoltage protection function, etc.
Negative-sequence based measurement is recommended in isolated or high-impedance earthed systems.
Zero-sequence based measurement is recom-mended in directly- or low-impedance earthed systems.
DesignThe function continuously measures the zero-sequence and/or the negative-sequence volt-age and current in three-phase ac voltage cir-cuits. It operates if the measured zero and/or negative-sequence voltage increases over the pre-set operate value, and if the measured zero and/or negative-sequence current remains below the pre-set operate value.
Two function output signals are available. The first depends directly on the voltage and current measurement. The second depends on the operation of the dead-line detection func-tion, to prevent unwanted operation of the distance protection if the line has been de-energised and energised under fuse-failure conditions. A special function input serves the connection to the auxiliary contact of the MCB (when used), to secure correct opera-tion of the function on simultaneous interrup-tion of all three measured phase voltages.
Control
Command control (16 signals)
ApplicationThe terminals may be provided with 16 out-put functions that can be controlled either from a Substation Automation system or from the built-in HMI. The output functions can be used, for example, to control high-voltage apparatuses in switchyards. For local control functions, the built-in HMI can be used. Together with the configuration logic circuits, the user can govern pulses or steady output signals for control purposes within the terminal or via binary outputs.

Synchro-check and energising check (SYNX)
ApplicationThe synchro-check function is used for con-trolled interconnection of a line in an already interconnected network. When used, the function gives an enable signal at satisfactory voltage conditions across the breaker that is to be closed. The synchro-check function measures the voltages on the busbar side and the line side. It operates and permits closing of the circuit-breaker when the set conditions are met, with respect to the voltage difference (UDiff), the phase-angle difference (PhaseDiff), and the frequency difference (FreqDiff).
The energising condition can be set to allow energising in one, or the other, or both direc-tions, e.g. live busbar and dead line. It is pos-sible to have different energising settings for a manual close command and an autoreclose command.
DesignThe synchro-check for double busbar arrangements includes the voltage selection function. From the auxiliary contacts of the breakers and disconnectors, the terminal can select the right voltage for the synchronism and energising function. The function is also designed to allow manual closing when both sides of the breaker are dead.
PhasingNote: This function is not separately avail-able. It is an addition to the Synchro-check and energising check described above.
ApplicationPhasing of network breakers is to be per-formed, together with synchro-check, when two asynchronous systems are going to be connected in order to avoid stress on the net-work and its components. The phasing func-tion compensates for measured slip frequency as well as the circuit-breaker closing delay.
DesignThe phasing function also includes the synchro-check function. The phasing func-tion is used when the difference in frequency is less than the set value of the frequency difference for phasing and larger than the set value for synchro-check.
Autoreclosing (ARxx)
ApplicationThe reclosing function can be selected to perform single-, two- and/or three-phase reclosing from eight single-shot or multi-shot reclosing programs. The three-phase auto-reclose open time can be selected to give either high-speed autoreclosing or delayed autoreclosing. Three-phase autoreclosing can be performed with or without the use of the synchronism check or energising function.
DesignThe autoreclosing function co-operates with the line protection functions, the trip function, the circuit breaker and the synchro-check function. It can also be influenced by other protection functions through binary input sig-nals.The autoreclosing is a logical function built up by logical elements.
Logic
Three-pole trip logic (TRIP)
ApplicationThe function is intended for use when only a simultaneous three-pole tripping of the circuit breaker(s) is required.
DesignTwo functional inputs initiate the outgoing trip command. The first will initiate the trip command only if the function is not blocked or its operation has not been switched off or the terminal is not in a test mode. The second functional input overrides all the above con-ditions. It is intended for use together with station protection functions, such as breaker failure protection or transfer trip commands received from the remote ends of protected power lines.
Single- or two-pole trip logic (TRIP)
ApplicationTRIP operates in single-pole trip mode for single-phase faults, in two-pole operating mode for two-phase faults (with or without earth) and in three-pole trip mode for three-phase faults. It is also possible to achieve three-pole tripping for both one-phase and two-phase faults.
Line distance protection terminal REL 511*2.01MRK 606 003-BEN
Page 10
Functions (cont’d)Functions (cont’d) The function is applicable for all terminals which have built-in phase selection function-ality and is used in applications where single-pole tripping is required for single-phase faults due to system stability reasons. The two-pole operating mode can be used on double-circuit parallel lines with single-pole breakers.
DesignSpecial functional inputs are provided for the initiation of a single, two and three-pole trip command. Decision to initiate outgoing trip signals in different phases depends on a pres-ence of corresponding phase selective signals on specially provided functional inputs. Additional logic circuits secure a three-pole final trip command in the absence of the required phase selection signals.
The function is equipped with logic circuits, which secure correct operation on evolving faults as well as after the reclosing on persis-tent faults. Special function inputs are pro-vided to override the internal conditions and initiate an instantaneous three-pole trip com-mand. These inputs could be initiated by dif-ferent external functions, such as station breaker failure protection, transfer trip from the remote end line terminal, etc.
Pole discordance logic, contact based (PD)
ApplicationBreaker pole position discordance can occur on operation of a breaker with independent operating gears for the three poles. The rea-son may be an interruption in the closing or trip coil circuit, or a mechanical failure result-ing in a stuck breaker pole. A discordance caused by one pole failing to close or open can be tolerated for a limited time, for instance during a single-phase trip-reclosing cycle.
DesignThe operation of the pole discordance protec-tion is based on checking the position of the breaker auxiliary contacts. Three parallel nor-mally-open contacts in series with three nor-mally-closed contacts in parallel for the respective breaker poles form a condition of pole discordance, connected to a binary input dedicated for the purpose.
Additional configurable logic
ApplicationConfigurable logic is included in basic. Addi-tional logic circuits including more AND/OR gates are also available as an option. With this logic the user can configure different logical functions in the terminals to suit special requirements for different applications.
Communication channel test logic (CCHT)
ApplicationMany applications in secondary systems require testing of some functionality with confirmed information about the result of the test. Channel test function perform testing of communication (power line carrier) channels in applications, where it is not possible to monitor them continuously by some other means.
DesignThe logic initiates the sending of an impulse (carrier send signal), which starts the opera-tion of different external functions and checks the feedback from the external function. It reports the successful or non-successful response on initiated test. It is also possible to abort the test with an external signal, which overrules all internal process.
Binary signal transfer to remote end (RTC)
ApplicationThe binary signal transfer function is prefera-bly used for sending communication scheme related signals, transfer trip and/or other binary signals required at the remote end. Up to 32 freely selectable binary signals, internal or external to the terminals, can be transmit-ted in both directions over a protected line.
DesignTogether with the binary signals internal to the terminal, the function is utilising binary inputs and outputs. The function can be pro-vided with various 56/64 kbit/s communica-tion modules for fibreoptic or galvanic connection. For more information about the available communication alternatives, see ‘Remote end data communication’.

Binary signal interbay communication
ApplicationOne receiving function block for 16 binary signals and with fast execution time is used to receive information over the LON bus from other REx 5xx terminals. The other terminals must have a corresponding Event function block to send the information. Additional 79 receiving blocks with slower execution time are also available as an option.
Monitoring
Disturbance recorder (DREP)
ApplicationThe disturbance recording function is an important part of a station monitoring system, which enables the evaluation of different events within the power system. The high-performance disturbance recorder can memo-rise up to 10 analogue channels and 48 binary signals (internal signals to the terminal and/or external signals connected to the binary inputs of the terminal). Any of the recorded analogue channels and binary signals can be programmed to start a recording.
Furthermore, analogue channels are program-mable for over- and under-functions and the binary signals can start recording on transi-tion from a logical 0 to a logical 1 and vice versa. Pre-fault, post-fault and limit time can be set in wide ranges. Collection of distur-bance records is possible locally as well as remotely, using HMI software. Evaluation of the disturbances can be done in the program, type REVAL.
Event recorder (EVR)
ApplicationAn event recording function is available. It presents in a logical order, starting and trip-ping signals that have occurred in the termi-nal. Up to 150 time-tagged events for each of the last 10 recorded disturbances are stored. Also internal events, such as setting changes, are stored in the event recorder.
Fault locator (FLC)
ApplicationAn accurate fault locator is an essential com-plement to the line protection. The fault locator provides distance to the fault together with information about the measuring loop that has been used in the calculation. Possi-bility of recalculation with changed para-meter settings exists. Information on the last 10 disturbances are available.
The fault locator algorithm compensates the effect of the load currents, the apparent fault resistance and zero sequence mutual imped-ance.
Trip value recorder (TRVAL)
ApplicationInformation on the actual primary and secon-dary phasors of the voltages and currents are available in the trip value recorder. The pre-fault and fault values of the applicable volt-ages and currents are recorded with their phase relations for the last 10 disturbances.
Increased measuring accuracy for U, I, P, Q
ApplicationTo reach a high accuracy in the measure-ments, a factory calibration of the five current and the five voltage input transformers is made.
Metering
Pulse counter logic
ApplicationThe pulse counter function provides the Sub-station Automation system with the number of pulses, which have been accumulated in the terminal during a defined period of time, for calculation of, for example, energy val-ues. The pulses are captured on the Binary input module that is read by the Pulse counter function. The number of pulses in the counter is then reported via LON to the station HMI or read via SPA as a service value. The nor-mal use for this function is the counting of energy pulses for kWh and kVarh in both directions from external energy meters.

Activation of active setting group (GRP)
ApplicationDifferent system operate conditions require different settings of protection functions used. The 500 series terminals have basically four sets of independent setting groups built-in, which contains all setting parameters for all protection-, control- and monitoring func-tions used. The user can change the active setting group at any time, locally by means of local HMI or a personal computer, or remotely by means of SMS and SCS as well as by activation of the corresponding func-tional inputs to the GRP function. Adaptive changing of the active setting group is possi-ble by means of the GRP and some other functions, available within the 500 series ter-minals.
DesignThe GRP functional block has four functional inputs, each corresponding to one of the set-ting groups stored within the terminal. Acti-vation of any of these inputs changes the active setting group. Four functional output signals are available for the configuration purposes, so that continuous information on active setting groups is available for different purposes.
Dead-line detection (DLD)Note: This function is not separately avail-able. It is an addition to the automatic switch-onto-fault function, the weak-end infeed detection function and the fuse failure func-tion.
ApplicationDifferent protection, control and monitoring functions require for their proper operation information on the condition of a protected element, such as power lines, etc. The DLD function detects the conditions of a protected element, whether or not it is connected to the rest of the power system.
DesignThe function continuously measures all three phase currents and phase voltages of a pro-tected power line. The line is declared as a dead (non-energised) line if all three mea-sured currents and voltages fall below the pre-set values for longer than 200 ms.
The function operates on a phase-segregated basis, if single-pole trip logic has been selected for a particular terminal.
Serial communication
ApplicationOne or two optional optical serial interfaces, one with SPA or IEC 870-5-103 and the other with LON protocol, for remote communica-tion, enable the terminal to be part of a Sub-station Control System (SCS) and/or Substation Monitoring System (SMS). These interfaces are located at the rear of the termi-nal.
Two buses can be built up, one independent of another, each of them with different func-tionalities regarding monitoring and setting of the functions in the terminal. Plastic fibres can be used up to a distance of 30 m (90 ft.). Glass fibres for distances up to 500 m (1500 ft.).
An optical network can be used within the SCS system. This enables communication with the terminal through the LON bus from the operator’s workplace and the control centre.
The second bus is used for SMS. It can include different numerical relays/terminals from the PANORAMA range with remote communication possibilities. Connection to a personal computer (PC) can be made directly (if the PC is located in the substation) or by telephone modem through a telephone net-work with CCITT characteristics.
Time synchronisation
ApplicationThe terminal has an internal clock, which can be synchronised by means of a minute pulse through a binary input or via the station bus communication.
Local HMI
ApplicationThe HMI (Human-Machine-Interface) serves as an information unit, presenting in a logical order starting and tripping signals that have appeared during each of the last ten recorded disturbances.
Line distance protection terminal REL 511*2.01MRK 606 003-BEN
Page 13
Furthermore, each of the two local HMI pos-sibilities takes over the functionality of the measuring instruments such as the A-meter, V-meter, VAr-meter, W-meter and Hz-meter. The current statuses of all binary input sig-nals and internal logical signals are available too.
Ac/dc measurements
ApplicationThis function provides three-phase or single-phase values of voltage and current. At three-phase measurement, the values of active power (W), reactive power (var), frequency (Hz) and the mean value for voltage (U) and current (I) can be calculated.
Alarm limits to be used as conditions in the configuration logic can be set. Besides the direct inputs of voltage and current, analogue inputs for mA signals are also available.
Self-supervision with internal event recorder
ApplicationThe self-supervision function operates con-tinuously and includes:
- Normal micro-processor watchdog function
- Checking of digitized measuring signals
- Checksum verification of PROM contents
- Checksum verification of types of signal communication
- Read-Write-Read-Write cycling of the memory cells and internal registers
The self-supervision status is available from the local HMI or via a SMS or SCS system.
When an internal fault has occurred, you can retrieve extensive information about the fault from the list of internal events available in the terminal from SMS or SCS. A time-tagged list with the date and time of the last 40 inter-nal events is available here.

Functions (cont’d)Functions (cont’d) Remote end datacommunication
ApplicationThe line distance protection terminals are using the communication facilities below, except the dedicated links, together with the optional function, binary signal transfer to remote end.
The fibre optical module can communicate without additional units over dedicated fibres up to around 30 km. When greater distances are required to be covered, an external FOX 20 system, available from ABB Net-work Partner Ltd. (Switzerland), can be used. The FOX 20 works as a repeater in this case and is optically connected, sending the sig-nals on dedicated fibres. With this configura-tion it is possible to cover distances up to 120 km on single-mode fibres. The FOX 20 can also operate as a multiplexer, in which case a number of 64 kbit/s data channels and RS 232 channel can be transmitted in parallel.
Direct galvanic connection to a multiplexer can be done up to a distance of 100 m. The built-in interface in these modules can sup-port the CCITT standard V.35/36 contra-directional, X.21 64 kbit/s and EIA RS 530/544 contra-directional 56 kbit/s communica-tion modes. V.35/36 and RS 530/544 co-directional communication modes can be sup-plied upon request.
The CCITT G.703 can be connected over an optional RS 530/544 contra-directional to G.703 converter. The distance between the terminal and the converter is limited to 10 meters.
When the distance is too great for direct galvanic connection, a short-range optical modem is used. The distance can be up to 5 km and the optical/galvanic converter can directly support CCITT standard V.35/36 contra-directional as well as X.21 and G.703 communication modes.
Direct galvanic communication over twisted pair cable for distances up to 4 km can be done using the short range galvanic modem.

Hardwaredesign
The REx 5xx series mechanical packaging and connecting system consist of a case in which printed circuit boards are inserted. The case is available in different sizes (widths) with the height 6U (265.9 mm). REL 511 is normally assembled in a case with the width 1/2x19". The cover is made of preplated steel sheet, with the different details spot welded together. The outside surfaces are painted light beige.
The front plate, which is made of aluminium profile, has a cut-out with a local HMI module.
The degree of protection is IP 40, according to IEC 529, for cases with the widths 1/2x19" and 3/4x19". IP 54, for the front area, can be obtained with accessories for flush and semi-flush mounting.
The REx 5xx series can be flush, 19"-struc-ture or projection mounted with different mounting kits available. Products assembled in the 1/2x19" and 3/4x19" cases can also be semi-flush mounted. Two cases 1/2x19" can be mounted side-by-side for maximum utilis-ing of space in 19" panels. A test switch, type RTXP, and/or COMBIFLEX modules are added in separate cases of the same basic design as the mechanical packaging of the 500 series. These cases, type RHGS, exist in sizes 1/4x19" and 1/2x19" and can be mounted by the side of REx 5xx products smaller than 1/1x19".
All connections are made on the rear of the cases with compression type screw terminal blocks for electrical connections. Serial com-munication connections are made by fibre optic connectors type Hewlett Packard (HFBR) for plastic fibres or bayonet type ST for glass fibres.
