摘要
简要介绍了电气二次设备实施状态检修的基本要求,讨论微机保护设备状态检修的内容、要解决的若干问题,及利用SEL保护的可编程逻辑功能实现操作回路监视和保护状态的方式。
This paper briefly introduces basic requirement of condition-based maintenance. And the maintenance elements and some unsolved problems are mentioned for mircocomputer-based relay protection equipment. Circuit monitoring and protection modes will be successfully implemented by PLC in SEL relay.
