摘要
针对牡丹江第二发电厂11型微机保护改造后发生误动的现象,通过分析误动保护的故障信息及软件流程,并结合现场模拟试验,找出了保护误动的原因,完善了不对应起动重合闸的回路,同时对设备改造中出现的问题,提出了自己的建议。
According to the phenomenon of misoperation due to protection reconstructing of 11 type microprocessor-based line in The second Power Plant, this paper finds out the reason of misoperation, and optimizes the circuit of uncorresponding position started reclosing by analyzing fault information of malfunction and software procedure and combining with simulation testing. Some suggestions are proposed for the equipment reconstructing.
