摘　　要：全国范围内越来越多的高压直流输电工程投入运行,其中5条线路运行对陕西地磁观测造成一定干扰。统计2014年1月—2018年6月陕西地磁观测受高压直流输电影响情况,分析各地磁观测台受高压直流输电线路影响的特征,提出判别直流输电干扰线路的方法和应对高压直流输电干扰的建议。More and more HVDC transmission projects have been put into operation nationwide.Five of them have caused some disturbance to the geomagnetic observation in Shaanxi.The influence of HVDC transmission on the geomagnetic observation in Shaanxi Province from January 2014 to June 2018 is added up.The characteristics of the influence of HVDC transmission lines on the geomagnetic observation stations are analyzed and some suggestions for dealing with HVDC transmission interference are put forward.
