| 摘 要： | 雷击故障是输电线路的主要故障,识别雷击故障原因能有效提高和改进输电线路的雷击可靠性水平.结合220kV输电线路雷击故障的现场调查数据,采用雷电定位系统得到的雷电流参数在电磁暂态仿真软件ATP-EMTP建立输电线路雷击过电压仿真模型,分析了输电线路在不同雷电流下的跳闸性质.仿真结果表明,基于雷电定位系统和电磁暂态仿真能有效判别线路故障的性质,为线路的运行、维护和改造提供参考.

| Abstract: | Lightning failure is the foremost fault of transmission lines.Identifying lightning faults reasons are contributed to improve the lightning reliable levels of transmission lines.Combining 220 kV power transmission lines lightning failures field investigation data,using the lightning currents and location parameters from lightning location system,transmission lines lightning overvoltage simulation model are build in the electromagnetic transient simulation software ATP-EMTP and lightning tripping properties in different lightning currents are analyzed.The simulation results show that based on the lightning location system and electromagnetic transient simulation,properties of line failures can effectively identified and the references to the operation,maintenance and modification are provided. |
