摘要
超高压电网中,远方收信跳闸保护是非常重要的辅助保护。随着微机保护技术的发展,远方收信跳闸保护的设计规范和配置方案等也相应发生改变,使各变电站同时并存多种配置方式的远方收信跳闸保护,给现场继电保护和变电运维操作带来一定困难。针对远方收信跳闸保护在超高压电网中实际应用的各种典型配置方式,分析其动作原理、优缺点及调试运维注意要点等,可为现场继电保护调试分析和变电运维操作等提供参考。
Remote receiving trip protection is an important auxiliary protection in ultra-high voltage power grids.With the development of microcomputer protection technology,the design specifications and configuration schemes of remote receiving trip protection also change accordingly,making it difficult for on-site relaying and substation operation and maintenance operations to have multiple configuration modes of remote receiving trip protection coexisting in each substation.Regarding the various typical configuration methods of remote receiving trip protection applied in ultra high voltage power grids,it analyzes their operating principles,advantages and disadvantages,as well as key points for debugging and operation.It provides reference and guidance for on-site relaying protection debugging analysis and substation operation and maintenance operations.
