直流系统合闸母线运行方式对蓄电池组的影响及对策

The Effect on the Battery Set in the Closing bus Bar Operating Mode of A.D.C System and Its Countermeasure

对于直流负载存在大容量电磁式合闸机构的变电站,合闸母线的运行方式将直接影响蓄电池组的充电效果,本文通过建立变电站直流系统的等效电路,分析电磁式合闸机构开关在合闸操作过程中不同阶段对蓄电池充电的影响,提出了解决问题的方法,并结合现场有关实测数据进行验证。

The mode of operation of closing bus bar will effect on the battery charging efficiency directly in a substation which the large capacity electromagnetic of perating machine are used. In this paper,the author analyzes the battery charging efficiency in different stages while the machine is being operated to close by setting up a equivalent circuit of D.C system. A solving method is presented and has been proved by the field data.
