摘 要：根據(jù)500 kV王店變電站直流系統(tǒng)狀況，從保證蓄電池組安全、維護(hù)人員人身安全和系統(tǒng)運(yùn)行安全三個(gè)方面分析了接線中存在的問題，給出了直流系統(tǒng)接線方式的改造方案。針對(duì)改造后直流系統(tǒng)存在的不足，建議該變電站采取“兩蓄三充”的接線模式，進(jìn)一步提高直流系統(tǒng)的供電可靠性。
關(guān)鍵詞：變電站；直流系統(tǒng)；改造

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
