摘要
智能变电站安装静止型无功发生器(SVG)和晶闸管投切电容器(TSC)等柔性交流输电系统(FACTS),可综合利用两类装置优点,实现智能、柔性、动态地补偿所需无功。文中从原理、结构、性能及控制策略几个方面介绍了GM(GMRP动态组播管理协议)智能变电站SVG及其与TSC构成的FACTS装置智能协调控制系统,同时剖析了一起试运期间的SVG保护跳闸事件,找出了跳闸原因,即系统电压谐波含量突增,引发相关保护误动。最后给出相关整改措施及建议,希望为同类柔性输变电设备(如STATCOM、UPFC等)的设计、运检提供一定参考和帮助。
The intelligent substation equipped with both SVG and TSC devices can use the combination advantage of them to achieve smart, flexible and dynamic compensation for the required reactive power. This paper mainly introduces the GM intelligent substation＇s SVG and its intelligent coordination control system with TSC from the aspects of principle, structure, performance and control strategy. At the same time , it analyzes the SVG protection tripping event, and finds out the reason, That is, the system voltage harmonic surge triggering related protection malfunction. In the end it gives the relevant rectification measures and recommendations, hopping useful for the design and inspection of the similar FACTS equipments＇（ such as STATCOM , UPFC , etc. ） .
