Title: Application of Static Synchronous Compensator in Zhongshan Power Grid
Abstract: This paper studies engineering practice of ±8 Mvar static synchronous compensator in 220 kV Diguang substation of Guangdong Zhongshan power grid.It introduces design scheme of STATCOM in aspects of selection for capacity,connection way of the system,the main circuit configuration,installation way,heat dissipation and protection and analyzes its control strategy.By actual measurement for voltage curves of working days of 10 kV bus and response characteristic curves of open loop and close loop,it analyzes application effect of STATCOM.It discovers that after STATCOM taking part in voltage adjustment,the voltage of bus is stable at 10.4 kV and STATCOM is able to realize full load in one period which may immediately respond to change of the voltage and reach to a stable value in 306 ms.The application effect shows that STATCOM is provided with advantages of rapid response speed and smooth and continuous adjustment which is a kind of ideal equipment for implementing power quality regulate and control.
