The Analysis about the Impact of HVDC Monopole Operation on a 220kV Station

Abstract:

With the wide application of high voltage direct current, it also created some problems, such as transformers dc bias. This article describes the impact on the transformer of the operation of HVDC monopole mode, introducing the model used in the soil and the ground electrode potential distribution, it also calculates the ground voltage in the case of a single or double ring grounding .Besides this paper describes the potential level of the two layers of soil structure calculation method and uses this method to analyze the influence on 220kV station of the 500kV Tian-Guang HVDC monopole operation mode. The conclusion is that the operation mode has seriously affected the station.
