摘要
分析小电流接地系统接地故障特征,建立小型配电网仿真模型,模拟中性点不接地、中性点经消弧线圈接地等不同系统运行工况下各类单点接地、多点接地故障。对RTDS系统仿真波形进行分析,通过仿真不同系统工况下的接地故障,形成测试项目从易到难的闭环仿真测试平台,同时应用本测试平台完成多台不同原理选线装置的选线性能测试工作。
Based on the analysis of fault characteristics in small current grounding system, a simulation model of small distribution network is introduced. The simulation model may be used to calculate fault cases of single-point grounding and multi-point grounding conditions in ungrounded and neutral grounding via arc extinguishing coil systems. By means of different fault cases simulation on different power system conditions, a closed-loop simulation testing platform is conformed.With the testing platform, several line selection devices tests with different principles have been accomplished.
