基于网络通路的区域电网故障行波定位方法

在双端行波定位方法的基础上,提出了一种基于网络通路的区域电网行波故障定位新算法.该算法在不依赖于断路器状态信息的前提下,根据电网中各变电站记录的所有初始行波到达时间和电网的拓扑结构信息进行融合处理和容错分析,从而在某台录波装置故障、启动失灵或时间记录错误后仍能进行故障定位.理论分析和EMTP仿真结果表明,即使在较少的行波录波装置的情况下,该算法对所有电网具有较强的容错性和较高的定位精度.

Network Path Based Algorithm for Regional Power Grid Fault Locating with Traveling Wave

According to dOuble-terminal traveling wave fault locating(TWFL),a new regional power grid TWFL algorithm based on the network path is presented.The algorithm not depends on status information of the circuit breaker and can carry fault-tolerant analysis and fusion processing in accordance with the arrival time information of the initial voltage traveling wave of substations and topology structure for power grid.Thus the accuracy of fault locating still can be guaranteed even though a wave recorder breaks do...
