摘要
以分布参数作为高压输电线路的模型,提出了利用线路一端电压电流和另一端电流(或电压)的测距方法。根据故障类型可求出两端数据采样不同步角δ,可对不对称短路故障进行准确测距。其测距精度不受对侧系统运行方式变化的影响。仿真计算表明,该方法有效。
This paper presets a new fault location method using one terminal voltage current and another terminal current (or voltage) based on distributed parameters line model. The two terminal data sampling unsynchronized angle can be acquired according to fault type. The method can precisely location for unsymmetrical fault and exclude the influences of fault resistance, system operation conditioin. The digital simulation verifies the high accuracy and applicability of provided algorithm.
