中文摘要: 针对小电流接地系统两点接地故障的复杂性以及理论分析的难度，建立了仿真模型，分析了全部4种类型的两点接地故障，得到了故障时相电压、零序电压和零序电流的特征，提出了一种判断两点接地故障的方法。最后，通过PSCAD/EMTDC软件进行了仿真验证。
Abstract:Aiming at the complexity and theoretical analysis difficulty of the cross-country grounded fault in the low current grounded system,a simulation model is established.Four types of the cross-country grounded fault are analyzed.Then,the characteristics of phase voltage,zero sequence voltage and zero sequence current are obtained.A method for detecting the cross-country grounded fault is proposed.Finally,the theoretical analysis is verified by PSCAD/EMTDC simulation.
keywords: cross-country grounded fault grounded fault the low current grounded system the distribution network
