Calculation of DC grounding current distribution by UHVDC mono-polar operation with ground return


When earth is used as the current return path of ultra high-voltage direct current (UHVDC) system, great DC current will flow in the earth, which will bring about great ground potential differences in a large area around the DC grounding electrodes. To investigate UHVDC grounding current, A three-layer earth model combining vertical and horizontal layers is… (More)
