摘　　要：并联直流电源技术解决了传统串联直流电源系统单个电池开路影响系统可靠性、新旧电池不能混合使用、无法在线全容量核容等问题。但目前大多数直流系统还是采用蓄电池串联型系统,迫切需要改造为并联型直流电源系统。文章针对现有传统直流系统,提出了具体的改造实施方案,并对某35 kV变电站改造实例进行说明。Parallel DC power supply technology solves the problems that the single-cell open circuit of the traditional series DC power system affects the reliability of the system,old and new batteries cannot be mixed,and full capacity cannot be checked online.However,most DC systems still use battery series systems,and it is urgent to transform them into parallel DC power systems.In this paper,a specific transformation implementation scheme is proposed for the existing traditional DC system,and an example of a 35 kV substation transformation is described.
