【摘要】 电网故障诊断是保证电力系统安全稳定运行的重要手段。针对中国目前电网自动化水平的具体情况 ,提出了基于开关跳闸信号、保护信息及故障录波信息的分层式故障诊断方法。用此方法不仅可以诊断简单故障和复杂故障 ,还可以判断故障类型、故障相别 ,并完成故障测距 ,为运行人员迅速切除故障、恢复运行提供了可靠的保证。据此原理设计的装置在现场应用效果良好更多还原

【Abstract】 Fault diagnosis is an important measure to protect the safe and stable operation of power systems. According to the actual conditions of the power system automation level in China, this paper presents a delaminated method based on switch tripping signals, protection messages and recorded fault information. This method can not only diagnose simple and complicated faults, but also distinguish between fault types and phases and determine fault location. It provides operators with reliable assurance to quickly eliminate faults.更多还原
