摘　　要：三峡左岸电站机组检修排水控制系统选用西门子PLC为核心控制单元,遵循"运行次数最少优先启动,停泵时先启先停"的控制逻辑,控制6台大功率深井泵的轮换选择和可靠运行,从而满足左岸机组检修排水的要求。The draining and controlling system for sets repair at the Three Gorges Left Bank Power Station uses Siemens PLC as the core control unit, and follows the control logic of ＂preferential start of the set with the least number of runs, first start first stop for termination of pumping＂ to control the rotational selection and reliable operation of six high-power deep well pumps, thus satisfying the requirements for overhaul drainage of the sets installed on the left bank.
