摘要
以磷酸铁锂电池组作为后备电源的变电站直流系统,不适合采用传统的接线方式。文中提出一种新的直流系统接线方式,将馈电母线和充电母线分别设立,配合快速切换开关,解决在变电站直流系统中采用锂电池的问题。另外还讨论了新接线方式下直流系统的运行方式,并通过一系列试验数据,证明方案切实可行。
The traditional connection mode of DC power system in transformer substation is unsuitable when the backup power is based on LiFePO4 batteries.The new connection mode of DC power system which separates power supply bus from batteries charge bus using an instant switch is proposed in this paper to resolve that problem.Besides,the operation of DC system under new connection mode is discussed.The data of experiment has proved that the new connection mode is feasible.
