雷击输电线路时杆塔各处雷电流监测仿真分析
|
摘要
基于PSCAD/EMTDC构建了输电线路杆塔仿真模型,根据输电线路的雷击情况,考虑在雷击塔顶、雷击档距中间以及雷击导线这3种情况下,分析线路杆塔中各处电流分布情况,可为安装在输电线路杆塔上的雷电流波形监测线圈提供理论依据。合理地布置雷电流测量线圈能够监测到击中本级杆塔、档距中间以及相邻几级杆塔的落雷,因而减小了监测装置的安装数量,而且也能更大程度地采集到雷电波形。综合考虑了采集到的雷电流波形的反演问题,最终定位了雷电流测量线圈的安装位置。
A PSCAD/EMTDC based transmission tower model has been constructed.According to the actual situation of lightning-struck transmission lines and considering three kinds of lightning strike conditions,i.e.,the top of the tower,the middle of the span and the conductor were lightning struck,the lightning current distribution throughout the transmission line and the tower was analyzed,and the analysis results could provide theoretical basis for installing lightning current monitoring coils on transmission towers.Rational configuration of lightning current monitoring coils makes the monitoring of the thunderbolt,which strikes onto local tower,the middle of the span and several adjacent towers,possible,thus the number of the installed monitoring devices can be reduced and lightning current waveforms can be acquired as more as possible.Synthetically considering the inversion of the collected lightning current waveforms,the installation positions of lightning current monitoring coils are located eventually.
