摘要：本文介紹一種采用并聯(lián)智能電池組件的新型分布式直流電源，與傳統(tǒng)直流電源相比，提高了蓄電池使用壽命、減少了維護工作量和直流系統(tǒng)絕緣故障點。針對110kV變電站的直流負荷情況、分布特點，對應用方案進行分析研究。將兩種直流電源方案從技術、經(jīng)濟兩個方面進行論證分析，為用戶提供更多的方案選擇。 敘詞：分布式直流電源 絕緣故障 并聯(lián)智能電池組件 Abstract：This paper introduces a new distributed DC power supply parallel intelligent battery assembly, it compared with the traditional DC power supply to improve the service life of the battery, reduce the maintenance and DC system insulation fault point. In this paper, according to the 110kV substation DC load and the characteristics of distribution.Two kinds of DC power supply scheme from two aspects of technology, economy analysis, provide more choices for the user.
