摘要
以蓄电池组为核心的传统变电站直流系统,在核容放电过程中会出现蓄电池组并联的情况,此操作难度大,容易导致环流和误操作的风险,严重威胁蓄电池的使用寿命。针对这一缺陷,本文提出用蓄电池并联保护器对蓄电池组进行独立的充放电管理,支持变电站直流系统的并联应用,并提出了其在变电站直流系统的应用方案。若该技术得到大力推广,则能够增强变电站蓄电池组的安全性,简化蓄电池维护作业程序,降低变电站的维护成本,具有广阔的应用前景。
The traditional substation direct current(DC) system using store battery groups, comes out a parallel operation of battery groups when discharge. This operation with high difficulty, brings risks of current circulation and mistaking operation, which threat the using age of store battery seriously. For this defect, a DC system parallel connection protector in substation and a control system managing for battery charge or discharge are proposed, which support substation DC system parallel connection. The heavy promotion of these technology, enhance battery safety in substation, simplify maintain procedure and reduce maintain cost of battery, have wide prospect of application.
