CM-UFD.M32 is a multifunctional grid feeding monitoring relay. It provides different monitoring functions in accordance with CEI 0-21 ed. June 2012. It detects over- and undervoltage (10 minutes average value, voltage increase and decrease protection) as well as any changes in grid frequency (double thresholds, frequency increase and decrease protection). The device is connected between the decentralized electrical energy source and the public grid in order to disconnect it, in case of problems, faults or maintenance into the grid.

FunctionsOperating controls
ApplicationThe grid feeding monitoring relay (SPI), that monitors network voltage and frequency, allows to disconnect distributed generation (GD) whenever the parameters are over the adjusted thresholds. Completely adjustable the CM-UFD.M32 assures the necessary flexibility to integrate medium and small production plants. In conformity to CEI 0-21 Ed. June 2012, the CM-UFD.M32 relay could be used in all the low voltage plants and in medium voltage plants with power less than 30 kW. The relay is mandatory in all low voltage production plants with power > 6 kW or with more than 3 generators (eg. Plants with more than 3 inverters).
Operating principle
Grid feeding monitoring relay according to CEI 0-21Programming mode and use
Protective functionsIf control supply voltage is applied and all phases are present with correct voltage and frequency values, output relay 11-12/14 (DDI) energizes and the start-up delay begins. When the delay is complete, output relay 21-22/24 energizes or de-energizes, depending on the configuration. The green LED U is on. If the measured values exceed or fall below the set threshold values, output relay 11-12/14 de-energizes after the adjusted delay and output relay 21-22/24 energizes or de-energizes, depending on the configuration, when the adjusted delay is complete. The fault type is indicated by the red LEDs F1 or F2. The threshold value that has caused tripping is shown on the display.As soon as the measured value returns to the tolerance range, taking into account a fixed hysteresis (less than 100 ms as requested by standard CEI 0-21), output relay 11-12/14 re-energizes without delay; output relay 21-22/24 energizes or de-energizes, depending on the configuration, when the adjusted delay is complete. When output relay 11-12/14 is re-energized the red LEDs F1 or F2 turn off and the fault message on the display disappears. The event that has caused tripping of the relay is recorded in the menu “events”.Protective function V>59 S1 med. (10-minutes average value): The relay calculates the sliding root mean square of the voltage value (in case of 3 phase 3 voltage values) over a period of 10 minutes. The voltage values are updated every 3 seconds. If the 10-minutes average value exceeds the threshold value, the output relays trip when the adjusted delay is complete.

Event listThe relay records and logs the last 10 events that caused tripping of the relay. Relevant information is available in the menu “Events” where the type of event such as protection or auto test are recorded as well as the time passed since the last tripping of the relay in hours, minutes and seconds. If the relay is switched-off and switched-on again, the measured time is reset.
Redundancy functionThe redundancy relay 31/32-34 (DG) is activated if relay 11/12-14 has de-energized and, within the adjustable time delay, no feedback from the external contact has been recognized by the internal logic via Y10-Y11. The external contact is connected in series to the coil of the relay itself, representing the status of the disconnection device. In case a feedback signal is present, the redundancy relay does not trip.
Relay 2 (21/22-24)Output relay 2 can be used for the closing command of the breaker motor. In case output relay 11/12-14 energizes the adjustable delay T1 starts. When T1 is complete, output relay 21/22-24 will be activated for the duration of the pulse time T2 or until relay 11/12-14 de-energizes.In this last case T2 is inactive (T2= LOCK). The operating principle of the relay 21/22-24 is configurable as normally energized (closed-circuit principle) or normally de-energized (open-circuit principle).
Local command and external signalThe CEI-021 standard defines “Restrictive thresholds”, the under- and overfrequency thresholds S1 (49.5-50.5 Hz), and “Permissive thresholds”, the under- and overfrequency thresholds S2 (47.5-51.5 Hz). Selection of S1 or S2 thresholds is made by the corresponding combination of the external signal and the local command, as shown in this table:
Note: In order to activate restrictive thresholds S1 also input Y30-Y31 has to be closed.
External Signal Local Command Frequency Range
0 0 Permissive S2
1 0 Permissive S2
0 1 Permissive S2
1 1 Restrictive S1

Output relays scheme
Remote tripThe control input Y20-Y21 can be configured as normally open or normally closed. If normally closed is configured, the grid feeding monitoring relay trips if Y20-Y21 is opened. If normally open is configured, the relay trips if Y20-Y21 is closed. Within less than 50 ms after activation of the remote trip input, output relay 11/12-14 de-energizes, and output relay 21/22-24 energizes or de-energizes, depending on the configuration. When the remote trip input is deactivated the output relays 11/12-14 and 21/22-24 trip again.
AutotestThe auto test function allows the verification of the protective functions operability. Selection of the function to be tested starts the auto test. The display shows the threshold value that increases or decreases until the input voltage or frequency value that causes tripping of the output relays is reached. If during the sweep any value of the function setting range meets the same value of the input quantity supplied to the relay (Voltage or Frequency), the function under test trips, operates the output relay and the display shows “OK”: the Autotest has verified that the relay trips correctly.If during the sweep no value of the function setting range meets the same value of the input quantity supplied to the relay (Voltage or Frequency), the function under test does not trip and the display shows “KO”: the Autotest has verified that the relay does not trip untimely.This is the case when the value of the input quantity supplied to the relay is the nominal one which, of course, is outside the functions setting range.To have the function tripping during the Autotest, the input quantity must be arranged to a value within the function setting range. The result is stored in the event list.
