Abstract: According to DC System Conditions of 500kV Wangdian Substation, analysis was made to the problems of wiring from three aspects of assuring storage batteries groups, maintaining personnel life safety and making system operation safe. The reform scheme of DC system wiring method was given. Aiming at that there existed insufficient points after reform of DC system, this paper suggested adopting “two storage batteries and three chargers” wiring mode in the substation, so as to raise power supply reliability of DC system further.
Key words: substation; DC system; reform
