摘要
苏南500 kV统一潮流控制器(unified power flow controller,UPFC)工程是目前世界上电压等级最高、容量最大的统一潮流控制器工程,用于解决苏州南部电网潮流分布不均、断面超限、无功支撑能力不足等问题。本文概述了苏南UPFC的工作原理及保护配置方案,对典型故障点的保护动作结果进行了阐述说明,为今后更高电压等级的柔性输电系统保护研究提供了参考。
Unified power flow controller in Suzhou 500 kV Southern Power Grid is the highest voltage class and largest capacity UPFC project in the world. It is used to solve the problems of uneveu power flow distribution, over-limited sectional flow and poor dynamic reactive support ability, et al. The principle and protection configuration scheme of UPFC are summarized, and the action results of typical fault points are expounded in detail. The research of 500 kV UPFC in this paper provides a reference for the studv of the nrotection of the flexible transmission svstem with hieher vohage levels in future.
