Automatic Voltage Control Design of Power Supply System with Dynamic Reactive Power Compensator SVC

On the basis of introducing the design background of automatic voltage control, the structure, configuration, algorithm, process, key technology and applications of the AVC system are illustrated, highlighting the combined application of many new technologies such as data collection and monitoring, real-time control and rapid compensation, human contact adjustment and optimization, historical data management, etc. Test run showed that the AVC of power supply system＇s control method of one-level plus two-level, realizing the advanced AVC system and the reliable and stable of the compensation function. Area dispatching is well adjusted on reactive voltage on the basis of the coordinated control of dispatching side and terminal. Dynamic SVC, using capacitor voltage control based on DC side and system reactive current feedback control, is used in AVC to improve the control ability of reactive voltage as well as the reliability and flexibility.
