500 kV GIS变电站雷电侵入波波形分析
|
摘要
以某500 kV GIS变电站为研究对象,将变电站和GIS出线段看作一个整体,在国际通用电磁暂态仿真软件ATP-EMTP中对变电站各个电气设备搭建雷电侵入波仿真模型,同时对避雷器的仿真模型进行了优化设计以满足现实避雷器的动作特性。仿真了在不同运行方式下,GIS内部雷电侵入波的实际情况,对比分析不同工况下侵入波的波形及其影响,并与实测的雷电侵入波进行比较证明了模型的准确性。
Taking a 500 kV GIS substation as the research object and regarding the whole substation and outgoing line as an integral,the lightning intruding surge simulation model for various electric equipment is established with the electromagnetic transient simulation program( ATP-EMTP),while the simulation model of arrester is optimized in order to satisfy the real operation characteristics. The real situation of GIS inner lightning intruding surge is gained by simulating different operating modes. The different lightning intruding surge waveforms are compared and analyzed as well as their effects. The accuracy of the model is verified by comparing with the real measured lightning intruding surge waveform.
