摘要
针对高压输电网的系统结构和保护配置,提出一种故障诊断的因果链分析法。引入了事件集概念,运用集合和链的数据处理方法,整合故障后的保护装置和断路器动作事件信息,建立逻辑信息模型,提出了构造成因果链的一套规范。利用因果链分析法,能够准确定位故障设备,评价保护动作情况,从逻辑上解释故障后的设备行为,实现对故障的重现。
This paper proposes a cause-effect chain method of fault diagnosis for the system configuration and protection of high voltage transmission grid. A new concept of issue set is introduced and the logical information model is created by using data-processing method of set and chain, and collects information of protections and breakers af- ter the fauh. Therefore, a set of standard is defined to form the cause-effect chain. Taking the advantage of the method, we can better localize the malfunctioning equipment, evaluate how the protection is, explain the move of the equipment after the fault logically and reply the fault.
