摘要
本文设计了发电机双电源切换控制系统并编制了控制程序,为发电机控制系统提供安全稳定的工作电源,本系统以西门子LOGO系列可编程序控制器为核心部件,以西门子公司3VL系列带电动操作机构的断路器为执行部件,实现对发电机控制系统主备用电源切换的控制,并在国内外很多大中型水电站发电机控制系统中得到了很好的应用,受到用户的好评。
This paper designs two power changing-over control system of generator and the preparation of the control program, provides for the security and stability of the power supply for hydropower station generator control system. This system uses of Siemens LOGO series programmable controller as the core components, 3VL series with Siemens breakers with motorized operating mechanism for the implementation of components, hydropower station generator control system to realize the main and backup power switching control. Many medium-sized hydropower stations at home and abroad to get a good application, praised by users.
