摘　　要：安康电站尾水门机电气控制系统在改造前故障时有发生，严重影响电站正常生产，甚至威胁到电站防汛工作的开展。对门机电气控制系统进行PLC改造后，电气响应速度加快，设备动作率极大提高，而且设备操作简便，维护简单。通过近一年运行实践表明门机电气控制系统运行稳定，安全可靠性增强。Before alternation, failures often occurred in the hoist control system of tail water gate in Ankang Hydropower Station, which had impact the normal electricity generation. After alternation with PLC, the system is in response quickly, the equipment action speed enhanced, and the operation safely and maintain much easier.
