摘要
针对混合储能在直流系统应用的可行性,利用Matlab仿真和试验相结合的方法对其在大脉冲电流下功率分配进行测试分析。结果证明,直接并联混合储能系统能提高功率输出能力,满足变电站直流系统工况需求,且减少了阀控式铅酸蓄电池端电压的大范围波动,缓解了大电流对蓄电池的冲击,延长了蓄电池的使用寿命。
Aiming at the feasibility of the direct parallel hybrid energy storage application in the DC system, the method of Matlab simulation and the experimental combination to measure and analyze the power all^ation in a lm＇ge pulse electricity of hybrid energy storage was used. The results proved that directly parallel hybrid energy storage can improve the ability of power output, meet the demand of working condition of substation DC system, and reduce voltage of valve regulated lead acid （VRLA） batteries＇s wide fluctuations, ease the impact of the large current of battery and prolong the life of the VRLA battery.
