摘要
文章介绍了微机失灵保护的装设原则、应用情况。针对变电站系统的各种情况，介绍了微机型失灵保护装置的功能原理。指出失灵保护只要在工程上接线准确、设计方案合理，就能有效地防止拒动、误动，就能快速而有选择地切除故障，保障电网的安全运行。
This paper introduces the furnish principle and applications of micro-processor based failure protection. According to the situations of substation system, we introduced the function and principle of micro-processor based failure protection. And pointed out if project wiring accurate, design reasonable, the micro--processor based failure protection can effectively prevent maloperation or refusing-action quickly and selectively eliminate failure, security power network.
