基于PMU的双端同步故障测距算法的研究

Study on a Two-terminal Synchronous Fault Distance Measurment Method Based on PMU

基于分布参数的线路模型,推导了双端数据同步采样的测距算法。结合PMU的配置方案,对线路两端均装有PMU和线路一端装有PMU两种情况进行了ATP仿真分析,仿真结果验证了算法的有效性,在两种情况下均能满足故障测距的精度要求。

A distance measurment algorithm for two-terminal data synchronous sampling is derived based on a circuit model of distributed parameters. Combine with PMU configuration scheme, an ATP simulation for two-terminal both e- quipped with PMU and one-terminal equipped with PMU are taken. The results show that the arithmetic is availability and the precision requirement of fault distance in the two conditions can be met.
