Funksyonên Serek yên IED ya Kontrola Serxweban

Agahdarî ji Serxwebanên Têkelekirin

Posîsyon Status: Open, closed, or intermediate positions.
Control Pressure Status: Hydraulic, pneumatic, or gas pressure levels.
Auxiliary Contacts: Additional status signals such as low pressure, fault conditions, etc.

Hardwired Inputs: The Circuit Breaker Controller uses hardwired input contacts to gather various status information from the circuit breakers, including:
Analog-to-Digital Conversion: The controller converts these analog signals into digital format, making the data compatible with modern communication protocols.

Komanda Kontrola Serxweban

Hardwired Outputs: The Circuit Breaker Controller uses hardwired output contacts to send trip or close commands to the circuit breakers. These commands are executed based on instructions received from protective devices, SCADA systems, or bay control units.
Phase-Segregated Circuits: The controller typically provides phase-segregated tripping and closing circuits, allowing independent control of individual phases (A, B, C) or three-phase operations. For a three-phase circuit breaker, it usually provides one close coil and two trip coils.

Komunikasyon bi Paqijeyên GOOSE

Publishing Information to Bay Level Devices: After gathering electrical information from the circuit breakers, the Circuit Breaker Controller converts this data into digital signals and publishes it to bay level IEDs via the process bus using GOOSE messages. This allows other devices in the substation to access real-time status updates.
Receiving GOOSE Messages from Bay Level Devices: When a power system fault occurs or a remote control command is issued, the related protective devices or bay control units publish corresponding GOOSE messages (e.g., trip command, close command). The Circuit Breaker Controller, acting as a subscriber, receives these messages and takes appropriate actions, such as tripping or closing the circuit breaker via its hardwired output contacts.

Repeated Tripping Prevention (Anti-Pump Function)

Preventing Repeated Tripping: If a circuit breaker is manually or automatically closed on a permanent fault and the closing signal persists, the breaker may attempt to close multiple times after each trip. To prevent this, the Circuit Breaker Controller includes an anti-pump function that ensures the breaker trips only once and prevents further closing until the closing circuit is de-energized by the operator.
Configuration Consideration: If the circuit breaker itself has an anti-pump circuit, the anti-pump function in the Circuit Breaker Controller should be disabled to avoid conflicts.

Circuit Breaker Coil Supervision

Close Coil Supervision: The Circuit Breaker Controller can monitor the status of the close coil using auxiliary relays. This is achieved by connecting the terminal to the negative pole of the power supply in series with the normally closed auxiliary contact (52b) of the circuit breaker. If the terminal is also connected to the close coil (CC), the auxiliary relays can provide supervision of the close coil's health.
Trip Coil Supervision: Similarly, the controller can supervise the status of the trip coil using auxiliary relays. This is done by connecting the terminal to the negative pole of the power supply in series with the normally open auxiliary contact (52a) of the circuit breaker. If the terminal is also connected to the trip coil (TC), the auxiliary relays can monitor the trip coil's condition.

Pressure Supervision and Blocking

Critical Pressure Monitoring: The pressure in circuit breakers is essential for their proper operation. Abnormal pressure levels can lead to malfunctions, reduced lifespan, or even damage to the breakers. Therefore, the Circuit Breaker Controller monitors all types of pressure signals (e.g., hydraulic, pneumatic, gas) in the related circuit breakers.
Pressure Block Functions: When a trip or close command is received, the controller implements pressure block functions to prevent unsafe operations. If the pressure is below a safe threshold, the controller will block the execution of the command to protect the breaker. These block functions ensure that the circuit breaker operates only under safe conditions.

Phase-Segregated Tripping and Closing Circuits

The Circuit Breaker Controller typically provides phase-segregated tripping and closing circuits, allowing independent control of each phase. For a three-phase circuit breaker, the controller usually includes:

One Close Coil: Used to close all three phases simultaneously.
Two Trip Coils: One for single-phase tripping and another for three-phase tripping. This design allows for flexible and precise control of the circuit breaker, depending on the specific requirements of the power system.

Conclusion

The Circuit Breaker Controller is a vital component in modern substations, bridging the gap between traditional analog circuit breakers and digital communication systems. By integrating advanced features such as GOOSE message communication, anti-pump functionality, and coil supervision, the controller enhances the reliability, safety, and efficiency of high-voltage circuit breaker operations. Its ability to gather real-time data and execute control commands ensures that substations can operate smoothly, even in complex and dynamic power environments.
