智能变电站智能终端异常故障分析

Analysis of Smart Terminal Abnormal Fault in Smart Substation

针对智能变电站智能终端异常导致的断路器拒动故障,对保护GOOSE出口相关内容进行了分析,证实保护装置"通道故障"虚端子没有连接是造成该故障的原因,处理后保护传动断路器正确。最后对智能变电站调试检验提出相关建议。

Aiming at the failure of the circuit breaker malfunction caused by smart terminal abnormity in smart substation,this paper analyzes the GOOSE export-related content of relay protection,which has verified that the disconnection of the virtual terminator″channel fault″of the relay protection device is the cause of the failure.After the processing,the relay protection drives the circuit breaker correctly.Finally,some suggestions are put forward for the debugging of the smart substation.
