【摘要】 以山西地磁场观测台站和山西、宁夏、山东部分地电场台站观测为例,分析其受宁夏—山东±660千伏直流输电工程运行的干扰情况。结果表明,高压直流输电工程的运行对山西地磁场观测及送受端换流站附近的宁夏、山东地电场观测影响明显,而对于直流输电工程中段的山西地电场观测无明显影响。更多还原

【Abstract】 Taking all geomagnetic field observation stations in Shanxi and some of geoelectric field observation stations in Shanxi,Ningxia and Shandong as examples,the interferences to them by the Ningxia-Shandong ±660 kV DC transmission line are analyzed.The results show that the HVDC transmission line has significant impact on geomagnetic field observation in Shanxi and on geoelectric field observation for stations located near converter in Ningxia and Shandong,but not for the geoelectric field observation stations located in the middle of the HVDC transmission line in Shanxi.更多还原
