摘要： 越来越多的高压直流(HVDC)输电工程在全国范围内投入运行,对地磁观测造成了较大.范围的干扰,这种干扰需要观测员进行数据预处理,以便产出可靠的地磁观测资料。本文通过对HVDC运行的故障特性、地磁台站与高压直流线路的相对位置以及对地磁观测资料造成的干扰形态进行分析,指出了HVDC对地磁观测造成的4个干扰特性,为识别、判定这种干扰提供了依据。

Abstract: High voltage direct current transmission ( HVDC) failure can affect the geomag-netic observation data in a large range and causes much trouble to data processing. With the number of HVDC projects growing,the problem has become even more acute in recent years. In order to produce reliable geomagnetic observation data, the relationship between HVDC failure and its characteristics on geomagnetic observation data should be known, although it is difficult to identify interferences from the HVDC failure. By conducting a comprehensive analysis on the large data set, four characteristics were obtained and intro-duced in this paper, which would provide an effective method for the observer to identify and judge the interferences on geomagnetic observation data caused by the H VDC failure.

Key words: Geomagnetic observation, HVDC, Characteristics
