| 摘 要： | 配电网结构相对比较复杂、运行方式多样,断线故障时有发生.其单相断线故障因特征不明显,所以监测效率低.提出了一种基于线电压为判据的单相断线故障诊断法,通过监测线电压向量变化,判断故障点,该方法解决了以往常规使用相电压、相电流变化为判据方法所存在的弊端,在很大程度上提高了单相断线故障的诊断率.

| Abstract: | The structure of the distribution network is relatively complex，with various operation modes，and disconnection faults occur from time to time.The single-phase disconnection fault has no obvious characteristics，so the monitoring efficiency is low.A single-phase disconnection fault diagnosis method based on the line voltage was proposed.By monitoring the change of the line voltage vector，the fault point could be judged.This method solved the disadvantages of the conventional method of using phase voltage and phase current change as the criterion，and improved the diagnosis rate of single-phase disconnection fault to a great extent. |
