摘要
比较了高压线路保护采用标准化设计前后电网重合闸运行方式的差异,研究了2套不同厂家的线路保护重合闸功能同时投入时电网运行的可靠性。根据智能变电站内IED设备双套配置、独立运行的特点,提出了利用保护三跳接点实现双套智能终端间重合闸互相闭锁的工程应用方案。
This paper compares the difference of line reclosing operation modes of before and after the standardized design is used in relay protection. The reliability of power grid with two sets of reclosing device from different manufacturers putting into operation at the same time is studied. Considering doubly-equipped and independently-operated characteristic of IEDs in smart substation, this paper introduces an engineering application of using permanent triple node to realize intelligent terminal reclosing function.
