AVR is damaged due to lightning strikes or power grid faults
Sensor transformer (PT) fuse blown or PT itself faulty
When AVR needs firmware upgrade or parameter adjustment, temporarily keep the generator set running
7.2 Operator Training
The prerequisite for the effectiveness of MVC is that the operator knows how to use it in emergency situations. Suggestion:
Incorporate MVC operations into the operator training plan
Clearly label the operation steps on the control panel
Regularly conduct simulated emergency drills
7.3 Coordination with Automation Systems
In modern power plants, MVC can also work in coordination with automation systems. Through the remote control interface, the status of MVC can be monitored in real-time by the monitoring system, ensuring timely notification to the operator and activation of backup control schemes in case of AVR failure.
