1.1 Application

In power system, the traditional random switching mode of circuit breakers will generate inevitably

over-voltage, inrush current, electromagnetic transient effect and so on, affect insulation and life of

equipment, and even induce protection malfunction. The CS (Controlled Switching, abbreviated

CS), as the ideal solution to solve the above problems, is a method of making circuit breaker close

or open at the optimum time instant. When switching no-load line, no-load transformers,

capacitors, reactors and other equipments, the CS can greatly reduce overvoltage as well as

inrush current during energizing and de-energizing operations, thus eliminating harmful electrical

transients to the electrical equipment and the power system, extending the life of electrical

equipment and improving the stability of the power system.

The typical application of this device is show in following figures.

Figure 1.1-1 Typical application of PCS-9830B

The PCS-9830B switching controller needs the input of the reference voltage used to determine

the controlled phase, and it usually selects the VT of circuit breaker busbar at source side as the

reference voltage. The input analog quantity detection of the controlled side is used as the criteria

whether the switching is finished. The binary inputs that the device needs are mainly close

commands and open commands of control system. The output contacts of controlled close and

controlled open are connected to the closing and opening circuits of breaker respectively, and it

can configure two sets of output module when matching circuit breaker with double jump rings.

Moreover, the device supports the sensor signal inputs, which are used to achieve real-time

monitoring of ambient temperature, control voltage, phase oil pressure, phase SF6gas pressure

and other external parameters, compensating for the influence of the parameters on the circuit

breaker operating time.

compensation values of this time and compensates it. Moreover, the device has the

compensation based on circuit breaker idle time and cumulative operation number of circuit

breaker, reducing the affect of the above factors on the mechanical properties of the circuit

breaker.

Automatically select the reference voltage and the charge direction

In double-busbar connection, it can automatically select the reference voltage according to

the auxiliary binary inputs, and in 3/2 busbar connection, it can automatically select the

reference voltage and the charge direction according to the auxiliary bina ry inputs and voltage

criteria to make it more intelligent.

Controlled switching of circuit breaker of loads with different characteristics using a single

device

The device is equipped two sets of setting for different closing and opening targets and the

settings can be set independently. As an example, for the two-direction control of the middle

circuit breaker in the 3/2 busbar connection, one PCS-9830B can finish the two-direction

control of controlled closing and controlled opening, more flexibly and adaptively.

Cooperates with synchronism closing operation

If the control system sends a synchronism closing command, this device can automatically

detect whether the VT voltage of the controlled side is alive; if any phase voltage of the

controlled side is alive, this device will output closing pulse after it receives closing command.

Supports control circuit breaker with phase-segregated mechanism or three-phase

combination mechanism

This device can support different types of circuit breaker mechanism through a relevant

setting. To the circuit breaker with phase-segregated mechanism, the control logic for each

phase is independent; and to the circuit breaker with three-phase combination mechanism,

the control logic for phase A is used to control the circuit breaker, and the relevant settings

about phase B and phase C will be inactive and hidden.

Output circuit design of combination of IGBT and relay

IGBT can achieve rapid control and discreteness of operation time is almost negligible.

High-performance general-purpose hardware and real-time calculations

Hardware structure of 32-bit DSP+ARM microprocessors is adopted. DSP is responsible of

logic calculation and logic output, and ARM is in charge of event and disturbance recording,

HMI, communication, and printing etc. High performance hardware ensures real-time

calculation for all functions in each sampling interval of this device. This device adopts 32-bit

high performance CPUs and DSPs, internal high-speed bus, and intelligent I/O. Both

hardware and software adopt modular design, which can be flexibly configured. Features

include versatility, easy expansion, and easy maintenance.

PCS9830B Switch ing Control ler 3-1Date: 2015-02-15

3.1 Overview

The PCS-9830B controls the circuit breaker close or open at the optimum time instant related to

the phase angle via time controlled switching operations, at the same time considering pre -strike

and arcing characteristics during the closing and opening operation as well as the influence of

external operating conditions. Taking the measurements, it can greatly reduce transient

overvoltage and overcurrent during energizing and de-energizing operations, thus extending the

life of electr ical equipment and improving the stability of the entire power system.

The PCS-9830B provides controlled closing/opening function, real-time compensation and

self-adaptive function etc.

3.2 Controlled Switching Control Strategy

The reasons why the inductive load and capacitive load generate overvoltage or inrush current

are different, which cause the closing or opening phase position of the circuit breaker are different.

So it is necessary to adopt different control strategies for different types of loads.

The closing or opening phase position of the circuit breaker also has relationship with the

grounded mode of the controlled target object.

The following table shows the ideal phase angle. Theoretically, if the system phase sequence is

three-phase positive sequence (A, B, C or B, C, A or C, A, B), the control effect is equivalent. The

phase angle ofUA

is taken as reference value.

3.4 Reference Voltage Selection Logic

This device can automatically select the reference voltage according to the related criterion. This

device supports two sets of configurations for predefined target phase angle control operation. If

the controlled circuit breaker is closed or opened with different load, this device can realize

automatic selection of two different control strategies.

If only one phase voltage is inputted, this device can calculate the other two phase voltages

according to the phase position relationship. This device can input three different reference

voltages, and this device can automatically select the reference side, the controlled side and the

target phase angle according to the reference voltage real-time value and the auxiliary contact

binary input values in different application field.

This device can support several kinds of reference voltage selection methods.

3.4.1 Logic for Single-busbar Mode

In single-busbar mode, the busbar is the No.1 reference side, and any one of three busbar phase

voltages can be used as reference voltage. The controlled circuit breaker is used to open or close

the controlled device. Only the target phase angle of the No.1 controlled side needs be set.

The output mode of this device can be select according to the busbar voltage. If the busbar

voltage is alive, the controlled switching logic will be in service after this device receives control

command; otherwise, this device will output control command directly. The side circuit breaker in

3/2 circuit breaker wiring mode has the same control logic as the single busbar mode.

3.4.2 Logic for Double-busbar Mode

In double-busbar mode, the No.1 busbar is the No.1 reference side, and the No.2 busbar is the

No.2 reference side. And any one of three busbar phase voltages of the two busbars can be used

as reference voltage respectively. The positions of the two busbar disconnectors are inputted tothis device. Only the target phase angle of the No.1 controlled side needs be set.

Figure 3.4-2 Double-busbar mode

The setting [Opt_RefVoltMode] should be set as 1: DoubleBB.

The auxiliary contacts of the busbar disconnectors are used to detect the positions of the two

busbar disconnectors. This device supports single-position (89a or 89b) and double-position (89a

and 89b) contact inputs.

The reference voltage is selected according to the positions of the two busbar disconnector s. If

the No.1 disconnector is closed, the voltage of the No.1 busbar is used as the reference voltage

preferentially. If the No.1 disconnector is opened but the No.2 disconnector is closed, the voltage

of the No.2 busbar is used as the reference voltage. If the positions of the two disconnectors are

abnormal at the same time, the selected reference voltage is kept.

When the reference voltage has been selected already, if the reference voltage is alive, the

controlled switching logic will be in service after this device receives control command; otherwise,

this device will output control command directly.

If the reference voltage has not been selected, this device will output control command directly if it

receives control command.

If the positions of the two disconnectors are opened at the same time, the alarm signal

[Alm_89b_BB1&BB2] will be issued; and if the positions of the two d isconnectors are closed at the

same time, the alarm signal [Alm_89a_BB1&BB2] will be issued. If the double-position of the

busbar disconnector is abnormal, the alarm signal [Alm_89_BB1&BB2] will be issued. These

signals will be reverted if the abnormal position situation is disappeared.

Only if the setting [Opt_Mechanism] is set as 0: Single-phase, this mode can be in service.

3.4.3 Logic for 3/2 Circuit Breaker Mode

In 3/2 circuit breaker wiring mode, the control of the center circuit breaker has two typical

operations.

1. The voltage of the No.1 busbar is alive and the No.1 circuit breaker (CB1) is closed, the No.1

controlled device is energized or de-energized by controlling the controlled circuit breaker

(center circuit breaker).

2. The voltage of the No.2 busbar is alive and the No.2 circuit breaker (CB2) is closed, the No.2

controlled device is energized or de-energized by controlling the controlled circuit breaker

And any one of three busbar phase voltages of the two busbars can be used as reference voltage

respectively. In this mode, this device can control the two controlled device to be energized or

de-energized respectively. So the target phase angles should be set respectively according to

load characteristic.

The setting [Opt_RefVoltMode] should be set as 2: CenterCB.

The auxiliary contacts of the side circuit breakers are used to detect the positions of the two side

circuit breakers. This device supports single-position (52a or 52b) and double-position (52a and

52b) contact inputs.

The reference voltage is selected according to the positions of the two side circuit breakers. If the

CB1 is closed and the CB2 is opened or the voltage of the No.2 busbar is dead, the voltage of the

No.1 busbar is used as the reference voltage. If the CB2 is closed and the CB1 is opened or the

voltage of the No.1 busbar is dead, the voltage of the No.2 busbar is used as the reference

voltage. If the positions of the two side circuit breakers are abnormal at the same time, the

selected reference voltage is kept.




If the reference voltage has not been selected, this device will output control command directly if it

receives control command.

The double-position of the busbar disconnector is abnormal, the alarm signal [Alm_52_SideCB]

will be issued. This signal will be reverted if the abnormal position situation is disappeared.

If a fixed control operation is adopted, the reference voltage selection logic is same as the single

busbar mode. For example, if only the No.1 controlled device needs to be controlled through the

center circuit breaker, the voltage of the No.2 busbar can be used as reference voltage.

3.4.4 Logic for Quadrilateral Wiring Mode

In quadrilateral wiring mode, to the controlled device of the No.1 controlled side, it needs that the

No.1 controlled circuit breaker (CB1) and the No.2 controlled circuit breaker (CB2) should be


31/164

configured with a PCS-9830B respectively.

Take the PCS-9830B which is configured for the CB1 as an example, the voltages (phase

voltages) of the No.1 reference side, the No.2 reference side and the No.3 reference side need to

be inputted to this device. The controlled device is energized or de-energized by controlling the

CB1. Only the target phase angle of the No.1 controlled side needs to be set.

the No.1 reference side to the No.3 reference side.





3.4.5 Logic for Line with Shunt Reactor Wiring Mode

In the line with shunt reactor wiring mode, if an independent circuit breaker is configured for the

shunt reactor, the PCS-9830B needs to select the reference voltage according to the position of

the shunt reactor circuit breaker, the positions of the line switches and the operation state of the

busbars.

The reference voltages (phase voltages) of the No.1 reference side, the No.2 reference side and

the No.3 reference side need to be inputted to this device. The No.1 controlled side is controlled

by closing or opening the circuit breaker (Controlled CB). Only the target phase angle of the No.1

decide the closing or opening point.

The states of the circuit breakers (CB1, CB2 and CB3) and the states of the line switches are also

inputted to this device. This device can support normal open contact, normal close contact and

double-position contact.

If the switch of the line is closed and the line voltage is alive, the voltage of the No.3 reference side

is selected as reference voltage preferentially. When the switch of the line is opened, if the circuit

breaker CB1 is closed and the voltage of the No.1 busbar is alive, the voltage of the No.1

reference side is selected as reference voltage preferentially. When the switch of the line is

opened, if the circuit breakers CB2and CB3are closed and the voltage of the No.2 busbar is

alive, the voltage of the No.2 reference side also can be selected as reference voltage.





3.5 Controlled Switching Function

This device provides complete controlled switching function: real-time compensation function and

self-adaptive compensation function. If the real-time compensation function is enabled, this device

can execute the controlled switching logic control according to predefined closing or opening time

settings. If the self-adaptive compensation function is enabled, this device can continually correct


33/164

3 Operat ion Theory


the deviation of target point according to the recent operation deviation, and the correction

amplitude can be configured by setting related parameters. The compensation function related

the parameters of temperature, control voltage, SF6 gas pressure, oil pressure, idle time and

operation number etc. can be enabled or disabled flexibly.

To achieve precise control and desired results, the dispersion and stability of the inherent

operation time of the circuit breaker mechanism is an important factor, and the dispersions of the

pre-breakdown time and arcing time have effect to the final control results. Therefore, it is

important to obtain the true and accurate time parameters and configure them reasonably.

3.5.1 Real-time Compensation Function

Real-time compensation function without deviation correction of external parameters

In this mode, the impacts of temperature, control voltage, energy storage level and SF 6gas

pressure etc. to the operation time of the circuit breaker are

ignored by disabling the related

settings in this device. See Section3.3for the details about the control process.

Real-time compensation function with deviation correction of external parameters

The operation time of the circuit breaker mechanism with the tiny changes of the parameters

of temperature, control voltage, oil pressure, SF6 gas pressure, idle time and operation

number etc. This device can sample these analog values to calculate the deviation of the

operation time. Then the operation time can be corrected on the basis of the deviation.

This device provides 8 analog sensors for sampling temperature, control voltage, three phase

oil pressures of circuit breaker and there phase SF6gas pressures. The statistics of idle time

and operation number can be automatically countered in this device.

3.5.2 Self-adaptive Compensation Function

Self-adaptive compensation function without deviation correction of external parameters

This device can automatically detect the operation finished instant of circuit breaker

according to the sudden change of the feedback signals, and record the operation time of

each phase. If the self-adaptive compensation function is enabled, this device can

automatically correct the deviation in next operation according to the finished operation

records to improve the precision of next operation.

The deviation correction mode of the self-adaptive compensation function can be set freely

through the settings [K_Calbr_Cls] and [K_Calbr_Opn].

Take the voltage zero-cross closing operation as an example, on the assumption that the

latest closing moment t2is after the target phase angle and the closing time is not changed,

if the setting [K_Calbr_Cls] is set as 0.5, the expected closing moment is t1(the current

deviation is half of last one); if the setting [K_Calbr_Cls] is set as 0.0, the expected closing

moment is t0; and if the setting [K_Calbr_Cls] is set as 1.0, the expected closing moment

is still t2.

Because this device has no history operation record when it is in service at first time, the

controlled switching logic will be executed according to predefined settings.

Figure 3.5-1 Deviation correction self-adaptive control

Self-adaptive compensation function with deviation correction of external parameters

The deviation correction function is supported in self-adaptive compensation mode. This

device can record previous operation deviation and external parameter values. It can correct

the deviation according to the related deviation correction setting in current operation. To

expectantly correct the operation time of the circuit breaker as expectation, this device

calculates the compensation value due to the changes of the external parameters in two

adjacent closing or opening operations by comparing the real-time values and history values

of the external parameters.

3.6 Auxiliary Functions

3.6.1 Frequency Compensation Function

If the frequency compensation function is enabled, this device will correct each phase waiting time

value according to the time period of the reference voltage and the target phase angle by

monitoring the frequency of the reference voltage. By this way, this device can compensate

control error due to the frequency fluctuation of system voltage.

3.6.2 Circuit Breaker Mechanical Characteristic Supervision

This device gets the operation information of the controlled circuit breaker according to the

feedback signals of the controlled side, and automatically records the operation characteristic of

the controlled circuit breaker or supervises the necessary circuit breaker characteristic in each

control operation to present the abnormal situation in the operation period of circuit breaker.

In normal situation, the operation time difference of a certain phase of the circuit breaker is within

a definite time period. This device can monitor the operation time difference, and if it detects that

the operation time difference (between the current operation time and the predefined reference

value) is greater than the predefined setting, a related alarm signal will be issued

([Alm_ClsTimeDiffx] or [Alm_OpnTimeDiffx], x: A, B or C).


35/164

3 Operat ion Theory


The three-phase operation time difference of the circuit breaker should be within a definite time

period. If this device detects the three-phase operation time difference is greater than the

predefined setting, a related alarm signal will be issued ([Alm_ClsTimeDiff3P] or

[Alm_OpnTimeDiff3P]).

If the compensation function of the external parameters is enabled, this device will calculate the

compensation value of the operation time of the circuit breaker due to these external parameters.

If the calculated compensation value is greater than the predefined setting, a related alarm signal

will be issued ([Alm_ExtVarCompTime_Cls] or [Alm_ExtVarCompTime_Opn]).

3.7 Measurement Functions

This device can sample the single-phase voltages of the No.1, No.2 and reference sides, and the

three-phase voltages and currents of the No.1 and No.2 controlled sides. It also can measure the

real-time frequency.
