Abstract

Abstract: Based on the geomagnetic second data of national geomagnetic stations, the interference of 27 high voltage direct current (HVDC) lines on H and D components of geomagnetic observation are counted, and the influence of HVDC transmission on H and D components of geomagnetic observation are studied. According to the statistical results, various interference forms of H and D components of geomagnetic observation affected by HVDC transmission are obtained, and the causes of these forms are analyzed, so that the interference forms of H and D components by HVDC are more clearly understood.

Key words: HVDC, Geomagnetic second data, H and D components, Geomagnetic observation
