【摘要】 对全国高压直流线路的分布情况进行统计,分析高压直流线路对沿线地震台站地磁观测的影响,得出2014年之前地磁台站受直流输电影响的分布特性,进一步根据台站的影响特性确定受哪条高压直流线路的影响。分析结果为高压直流对地磁台站影响的判定及预处理有一定的参考意义。更多还原

【Abstract】 Combined with statistics of distribution of national high voltage direct current(HVDC)lines,influence of HVDC line on geomagnetic observation of seismic stations along the lines is analyzed.The distribution features of the geomagnetic stations interfered by HVDC before 2013 are obtained.According to the influence features of the stations,the HVDC lines which interfere with the stations is figured out.The analysis results have certain reference value for the judgment of the influence of HVDC on the geomagnetic stations and the data pretreatment.更多还原
