摘　　要：宁夏至山东高压直流输电工程运行以来,对红山地震台地磁观测造成了很大影响。选取2013年6月9日至14日和2013年12月23日红山地震台受到高压直流输电干扰数据与昌黎地震台无干扰数据作参考,通过多台对比分析法、单台检测法找出干扰数据的判定和处理,提高识别高压直流输电干扰能力和数据预处理水平。Since high voltage direct current（ HVDC） transmission project from Ningxia to Shandong has been working,the geomagnetic observation in Hongshan Observatory is influenced. In this paper,the interference data by HVDC in Hongshan station and non-interference data in Changli station during June 9,2013 to December 23,2013 is chosen to compare. According to the multiple-observatory-comparing method and singleobservatory-inspecting method,the interference data could be identified,and the distinguishing capability of HVDC and pre-processing level for observation data can be improved.
