摘要
介绍了地铁低压配电系统的典型构成及可编程控制器(PLC)在其备自投控制中的应用特点。同时分析了PLC在地铁低压配电备自投的实际工程应用案例。工程实践表明,采用PLC组建工业低压配电系统能获得高性能、高性价比,并具有可靠、灵活、简洁等优点。
The typical configuration of low-voltage distribution system in metro industry and the characters of ABB s PLC application in auto change-over control are introduced,some cases about PLC application in metro industry are analysed.The engineering practice shows that the adoption of industrial low-voltage distribution system via ABB s PLC could achieve obvious performance,higher cost-performance ratio and better economic benefit.
