当前越来越多的电动汽车充电设施接入电网,不同充电模式的充电设施接入电网产生的谐波污染将对电网造成不同的影响.对电动汽车充电站内不同充电模式充电机之间的相互影响进行Simulink仿真和谐波分析.首先,建立电动汽车动力电池的仿真模型.其次,建立电动汽车不同充电模式充电机的仿真模型.然后,将动力电池仿真得到的充电曲线直接等效成时变电阻,并作为连续信号直接输入充电机模型进行仿真.最后,在不同充电场景下对不同充电模式充电机进行仿真,分析了不同充电模式的充电机工作时相互影响的谐波规律.%More and more electric vehicle charging facilities are connected to the power grid now, and the harmonic pollution caused by the charging facilities under different charging modes will exert different effects on the power grid. This paper researches the Simulink simulation and harmonic analysis of the mutual influence between different charging modes charger in the charging station. Firstly, the simulation model of the electric vehicle power battery is established. Secondly, the simulation model of the electric vehicle charger under different charging modes is established. Thirdly, the power battery charging curve by simulation is equivalent to time-varying resistance, and it is input as a continuous signal to the charger model for simulation. Finally, different charging modes in different charging scenes are simulated, and harmonic mutual influence law of different charging modes charger on working is analyzed.
