摘　　要：介绍了三峡地下电站厂房渗漏排水电控系统工作原理,提出了一种PLC在三峡地下电站厂房渗漏排水电控系统中的应用方案。该方案响应速度快、控制功能完善、运行安全可靠,满足电站无人值守设计要求。The working principles of the electric control system for leakage drainage in Three Gorges Underground Power Plant are introduced. An application scheme is then proposed to adopt the programmable logic controller（ PLC） in the system,which is of certain advantages such as the quick response,excellent control functions,and high operational reliability and safety. Thus,the unattended operation of the power plant could be realized.
