摘要
输电线路发生故障后，故障点将产生向变电站母线运动的行波，采集、记录在母线处测量到的故障电流行波波形，使用匹配滤波器法和小波变换法进行分析计算，可实现输电线路精确故障测距。根据上述原理研制成功了新型输电线路故障测距装置ＸＣ－１１。模拟试验结果表明：此装置具有很高的准确性。
Along a faulty transmission line transient travelling waves do appear. Collecting and recording the data of transient current travelling waves on faulty line, then analyzing and calculating these data by use of the method of matching filter and the method of wavelet transform, the precise location of the fault can be obtained. Based on this principle, a new device for fault location of transmission line XC 11 has been developed successfully. The simulation tests show that the fault distance measured by this device is precisen and reliable.
