摘要
基于分布参数电路理论,针对中性点不接地三相系统特点,提出了树型配电线路单相接地的多频法故障诊断。大量故障诊断的计算机模拟和在故障模型仿真线上的模拟故障诊断试验表明,方法有效。
Based on distributed parameter circuit theory,the algorithm of fault diagnosis-multifrequency excited method to locate single-line-to-ground fault on the ungrounded 3-phase system is proposed in accordance with the characteristic of the system. A lot of the simulation of the fault diagnosis by computer and the tests on the fault model simulation lines demonstrate that the method presented in the paper is effective.
