摘　　要：随着电力系统不断发展,对电力供应的可靠性、稳定性及安全性要求也越来越高。本设计采用的是双进线互为备用的接线方式,基于PLC实现备用电源自动投入监控系统设计。此设计共有自动模式和手动模式两种运行方式,在自动模式中,两条进线可互为备用,当两条进线均故障时,可由发电机进行供电,除自动模式以外还有手动模式以供操作;然后在对备自投装置的软件及硬件设计基础上,进行梯形图程序编写;最后通过使用软件组态王对所编程的程序进行仿真,能够很好地表现系统需求。With the continuous development of the power system,the requirements for reliability,stability,and safety of power supply are also increasing.This design adopts a dual incoming line backup connection method,which is based on PLC to achieve the automatic input monitoring system design of backup power supply.This design has two operating modes:automatic mode and manual mode.In automatic mode,the two incoming lines can serve as backup for each other.When both incoming lines fail,the power can be supplied by the generator.In addition to automatic mode,there is also manual mode for operation;Then,based on the software and hardware design of the backup automatic switching device,write a ladder diagram program;Finally,by using the software KingView to simulate the programmed program,the system requirements can be well represented.
