摘　　要：针对某汽轮发电机组凝水系统实际使用需求,介绍凝水调节系统自动控制的工作原理、组成和结构设计,采用PLC语言编制完成PID调节控制模块程序,该程序根据设定的水位值,自动向水位调节器执行机构发出模拟量指令信号,控制水位调节器开启或关闭至各管路的窗口,从而实现回水或排水功能。通过专门搭建的试验平台模拟实际使用工况对水位调节系统进行试验验证。试验验证结果显示设计的水位调节器及水位自动控制程序在各种变工况条件下均能维持水箱内设定的水位,为后续机组凝水系统安全稳定运行提供试验数据支撑。In this paper a condensate water system of the steam turbine unit, the author of this paper practial use requirements, condensate regulating system are introduced, the working principle of automatic control, composition and structure design, PLC language compiled the PID control module program, the program according to the water level of the set value, automatic water level controller to actuator signal analog instruction, control the water level regulator open or close to the window of each line, so as to realize water or drainage function. Through specially built test platform to simulate the actual working conditions of water level control system for the test. Test results show that the design water level regulator andwater level automatic control program can maintain in various operating conditions set water tank water level, for subsequent condensate system provide a test data to support the safe and stable operation.
