摘要 利用Matlab对单相线路故障两侧短路和单相线路故障左、右侧短路及单相线路故障缺相的运行进行仿真分析。重点研究单相线路故障时配网中压和配网低压的电压、电流变化情况,通过比较配网单相线路各种故障电压电流变化情况,结合配网运维经验,对配网单相线路故障类型进行科学分析与判断,为运行人员提供有效的配网单相线路故障判断依据。 In this paper, we used Matlab to simulate the operation of single phase circuit short fault on left side, right side and both sides and open-phase fault. We mainly focus on the changes of voltage and current of medium voltage side and low voltage side in distribution network in a single phase fault. Then we can determine the type of the fault relying on the analysis of voltage and current values in short circuit state and the distribution network operation and maintenance experience. This method can help maintenance staff to analyze and judge the single phase fault in practice.
