摘要
为使工矿电气工程人员对可编程控制器(PLC)有专业的了解,重点介绍了基于PLC的继电保护装置的过流保护电路设计、软件设计,以及调试的过程。通过试验及现场调试可知,该装置完全能满足恶劣工况条件下工矿企业对继电保护的要求,并为继电保护装置的检修及技术改造工作提供参考。
In order to make industrial and mining electrical engineers have professional knowledge of PLC, the design of over current protection circuit, software design and debugging process of relay protection device based on PLC have been introduced. The test and field debugging show that the device can fully meet the requirements of industrial and mining enterprises for relay protection under harsh working conditions, which can provide a reference for the maintenance and technical transformation of relay protection devices.
