摘要

为了减小特高压直流接地极入地电流对交流电网直流偏磁的危害

文中从优化直流接地极位置角度出发减小交流电网中直流偏磁危害。研究断裂构造与岩土类型对直流接地极预选选址的影响

并将预选极址采用网格点模式法划分网格区域

以直流偏磁站点数量最少与交流电网中直流电流总量最低为目标

筛选优化预选址区域

并确定最终直流接地极位置。研究表明:直流接地极极址应远离断裂构造

且极址应选择在地表为低阻率土壤以及地下为高阻率岩石区域

合理的直流接地极位置从源头上降低了直流接地极所引起的直流偏磁对交流电网的影响。

Abstract

In order to reduce the harm of grounding current of UHVDC grounding electrode to DC bias in AC power network

the harm of DC bias in AC power network is reduced by optimizing the position of DC grounding electrode.The influence of fault structure and geotechnical type on DC grounding electrode pre-selection is studied.The pre-selection electrode location is divided into grid areas by grid point mode method.Aiming at the minimum number of DC bias sites and the minimum total DC current in AC network

the pre-selection area is optimized and the final DC grounding electrode location is determined.The results show that the location of DC grounding electrode should be far away from the fault structure

and the location should be in the low resistivity soil on the surface and in the high resistivity rock area on the ground.The reasonable location of DC grounding pole reduces the influence of DC magnetic bias caused by DC grounding pole on AC network from the source.
