大型储能电机充电升速特性分析
|
摘要
为研究大型储能电机的风摩损耗功率对储能电机的充电升速特性的影响,根据某大型储能电机的惰转数据,首先推导了风摩损耗功率与转速的拟合表达式,并在此基础上建立了储能电机充电升速的数学模型;然后,在Matlab/Simulink软件环境下建立了相应的仿真模型;最后,对储能电机连续三次充放电过程及转速全范围情况下的充电升速特性进行了仿真计算,并通过试验验证了仿真模型的正确性。
The wind friction loss power of the large-capacity energy storage electrical machine(ESEM)may reach hundreds of kilowatt,which affects the charge and speed increase characteristics greatly.In order to solve the above problem,according to the rotary speed data of the ESEM,an analytical expression of the wind friction loss power versus rotary speed is deduced,on this basis,a mathematical model of the charge and speed increase is established.Correspondingly,a simulation model based on Matlab/Simulink software is set up.Finally,three charge and discharge programs in succession and the charge and speed increase characteristics within the speed range of ESEM are simulated and calculated.Furthermore,the experiments validate the simulation model.
