摘要
沙角C电厂投产以来 ,多次出现循环水控制系统故障导致机组跳闸的重大事故 ,暴露出该系统设计中存在的不足。为此 ,分析了旋转滤网控制逻辑和循环水泵的跳闸逻辑存在的问题 。
Multiple tripping failures of generator sets caused by faults of recycle water control system occurred in Shajiao C Power Station, which bared the defects in design of the system. The problems in the start stop logic of band screen and the tripping logic of recycle water pump are analyzed in this paper, and improvement measures are given as well.
