Optimization and application of automatic voltage control strategy in a large hydropower station

This paper focuses on the optimization and application of Automatic Voltage Control (AVC) control strategy of a large hydropower station, by introducing the basic principles of AVC, including system structure, control mode, distribution principle and security strategy, analyzing the problems of the current AVC system and proposing corresponding optimization strategies to further improve the AVC regulation performance and bus voltage qualification rate, and providing reference for the industry peers to improve the operational stability of the AVC system.
