According to logic constraint relationship between different events, the fault 0 引言 hypothesis was constructed; and remediation strategies were 自20 世纪 70 年代调度自动化系统在电网中 proposed considering complicated conditions such as data error, 应用以来[1]，在调度中心采用在线电网故障诊断系 loss or time-sequence distortion. Considering the correlation of relay protection operation and circuit connection, the objective 统，实现故障后快速的故障设备判定以及故障相 function with operation consistency of relay protection taken 关的保护及断路器动作行为分
