摘　　要：电池储能是电梯再生能量回收利用的有效方式,针对应用中储能系统容量优化问题,基于回馈电能功率/能量以及变换器电压等约束条件确定电池组边界条件。在此基础上,通过引入制动电阻辅助分流以及电压动态调整的方法,研究了吸收释放再生电能过程的控制策略,并在Matlab/Simulink中搭建仿真模型。仿真结果表明该控制方法可在稳定直流供电网电压的前提下实现再生能量的高效利用,同时有效减少电池系统容量和成本。Battery energy storage is an effective way for elevator regenerative energy recycling.According to the capacity optimization of energy storage system,the boundary condition of the battery pack is designed based on the power and energy of the feedback energy as well as the voltage constraints of the converter.Further,the control strategy is studied by introducing the shunt method of the brake resistance and the dynamic adjustment of voltage.And the simulation model is built in Matlab/Simulink.The simulation results show that the proposed control method can achieve high efficiency of regeneration energy under the condition of stable DC power supply voltage,and the battery system capacity and cost can be reduced effectively.
