摘要
静止无功补偿器对维持系统稳定运行有重要作用。提出了一种针对桥型电容器接法的无功补偿装置保护方法,新的保护方案不仅仅对简单的电容器故障有效,而且对桥臂同侧电容器同时击穿故障也起到保护作用。基于PSCAD/EMTDC仿真结果验证了结论的正确性。
The static var compensator plays a key role in keeping the stable operation of power system. A novel protection method for capacitor with bridge connection is proposed. This novel method does not only work for simple capacitor fault, but also for the simultaneous breakdown fault of the capacitors located in the same side of the bridge. The simulation results based on PSCAD/EMTDC prove the conclusion to be correct.
