Protection and monitoring functions:

Fault diagnosis and protection: Equipped with a complete fault diagnosis system, it can monitor the operating status of the module itself and the excitation system in real time. When overcurrent, overvoltage, undervoltage, overheating and other faults are detected, an alarm signal can be quickly issued and corresponding protective measures can be taken, such as cutting off the excitation output, starting the backup excitation, etc., to prevent the fault from expanding and protect the safety of the generator and the entire power system.

Communication and remote monitoring: With the help of Ethernet and RS-485 communication interfaces and multiple communication protocols, communication connection with the power system monitoring center is achieved. Support remote parameter setting, status monitoring and fault diagnosis. Operation and maintenance personnel can view the operating parameters and working status of the excitation system module in real time through the host computer, and remotely adjust the control strategy, which greatly improves the efficiency of equipment operation and maintenance and management convenience.
