摘　　要：介绍了一种基于PLC控制的新型蒸汽发生器水位控制系统。该系统采用电动给水泵变速调节和调节阀共同完成水位控制。电动给水泵电机采用变频器实现变速,调节阀采用新型的节流管式智能调节阀,通过PLC的各个模块控制给水泵电机转速和调节阀开度调节水位。A new type of control system for the feedwater level of steam generator based on PLC is introduced in this paper. The system employs the variable speed regulation of electrically driven feed pump and the regulator valve to fulfill the control of water level. The speed of electrically driven feed pump is changed by means of frequency converter, while the regulator valve is a new type of intelligent regulator valve in form of throttle pipe. The modulars of PLC control the rotational speed of electrical motor of water-feeding pump and the opening of regulator valve to regulate the water level.
