移动式SVC的设计及其在江西电网中的应用

结合国内首套移动式静止无功补偿器（SVC）在江西电网实施的工程经验，详述了系统设计方法。针对应用现场的实际情况，提出了带10 kV电压限值的220 kV电压基本控制策略以解决容性支路频繁投切的问题。同时根据移动式的特点，提出了基于分层分布式的监控系统和紧凑型的阀体设计方案，总结出系统现场试验方法及其调试应用中的一般原则和注意事项。文中得出的一些结论，可为SVC在中国电网中的进一步推广应用提供一定的指导和借鉴作用。

The Design of Relocatable SVC and Its Application in Jiangxi Power Grid

According to the project experience of the first relocatable static VAR compensator (RSVC) in China applied in Jiangxi power grid, some methods of project design are put forward. A new 220 kV voltage control strategy with 10 kV voltage limit is presented here to meet the requirement of transformer substation voltage control. For realizing the relocatable system, the distributed monitoring system and compact valve body design are applied. By the analysis of experimental and operational data, some beneficial principles and attentions are drawn when RSVC is applied. The conclusions will be good for the implementation of SVC in China power grid.
