摘要

应用EMTP对750 k V长距离检修状况下平行线路间感应电压和电流的计算

并进行实测

着重研究了检修线路接地数量对感应电压和感应电流的影响。结果表明:检修线路的接地数量与感应电压关系不大

与感应电流有很大关系;当在检修线路作业点工作时

除了线路两端变电站接地和作业点接地外

还需合理的布置作业段两端临时接地线。

Abstract

The induced voltage and the induced current between 750 k V long parallel lines under maintenance status are calculated by EMTP and measured on-site.The impact of the number of grounding to the induced voltage and the induced current is focused on.The result indicates that the influence of the number of grounding on the induced voltage could be neglect

but is great to the induced current.When the line is in maintenance and working on the maintenance spot

reasonable temporary grounding at both ends of the operating segment are needed in addition to both ends of the line substations.
