基于ANSYS的陕北换流站直流接地极地电位分布计算
Simulation Study on the DC Grounding Electrode Earth Potential Distribution of Northern Shaanxi Converter Station Based on ANSYS
摘要
Abstract
The distribution of earth surface potential needs to be calculated in UHVDC engineering planning and design.Based on the stratified earth resistivity data measured by magnetotelluric sounding method (MT method) from one China converter station project located in Daliushu Yan Village,Fugu County of Northern Shaanxi,a 6-layer earth soil stratification model is established.The potential distribution in the range of 100 km around the grounding electrode is analyzed by ANSYS under rated operating condition.The results show that the electric potential decreases rapidly in the range of 2 km around the DC grounding electrode,where the facilities of electric power,communications,railways and pipelines shall not be planned and built.The earth surface potential distribution of the built and planned substations and power plants in the area around the Northern Shaanxi converter station has been calculated,and the results can be used as a reference for the single pole operation debugging of Northern Shaanxi-Hubei UHVDC transmission project.关键词
