| 摘 要： | 针对T接输电线路故障测距问题,将行波故障测距方法应用于T接输电线路故障.首先进行故障分支的判定,其次,把复杂的三端输电线路通过运算化简为比较简单的双端输电线路,然后利用双端行波故障测距的方法进行故障测距,得到故障的位置.同时在行波测距装置中增加行波波形记忆模块、使用较高的采样精度,确保双端行波测距的可行性.

| Abstract: | Aiming at problem of fault location algorithm for three-terminal transmission lines faced by relay engineers,this paper applied the travelling wave method of fault location to three-terminal transmission lines.Firstly,the fault branch was decided,then,through the operation the complicate three-terminal transmission lines were simplified to simpler two-terminal transmission lines,finally,the fault position could be found by the way of two-terminal transmission lines based on travelling wave theory.At the sam... |
