Abstract |
Recently, there has been an increasing interest in HVDC(High Voltage Direct Current) transmission as a core technology required for a Super grid. Compared with HVAC(High Voltage Alternating Current) transmission, HVDC transmission has no loss due to skin effect and reactance components, so long-distance power transmission is possible, and asynchronous power system can be interconnected. Also, in case of a DC electric field, there is no induction phenomenon. However, the human body may cause irritation such as electrostatic discharge and discomfort, therefore electric field analysis through simulation is absolutely necessary. In this paper, electric field simulation was performed using COMSOL Multiphysics, a multi-physics analysis program, for a Bipolar single line DC ±400kV, DC ±500kV, DC ±800kV model. In order to verify the validity of the simulation, comparative analysis with the related literature was conducted. |
