摘　　要：串联补偿电容在丰-万-顺500 kV输电线路上的成功应用,为电力系统能量传输提供了更畅通、更经济、更可靠的通道,在实际运行中取得了很好的效果。二次系统设置完善的保护与控制功能,实现在异常或故障状态下电容器的自动退出运行,并在一次系统恢复正常后自动投入;同时,串联补偿电容保护与控制系统的动作还要与输电线路继电保护功能进行配合。Series compensating capacitors are successfully used in Feng-Wan-Shun 500 kV transmission line, providing rapid ,economic and reliable path for energy transmission in electric power system. The secondary system is equipped with perfect protection and control function,so the capacitor will be automatically out of service at abnormal or at fault condition and resume to work automatically after primary system is back to normal. Meanwhile the action of protection and control function of series compensating capacitors coordinates with the relay protection of transmission line.
