摘要
针对电动汽车充电机在工作过程中的谐波问题进行研究,通过搭建充电设备的仿真模型,模拟了充电过程中,充电设备对局部电网供电质量的影响,仿真结果表明,在变压器的电源侧几乎不会受到充电设备负载的影响,充电设备的主要影响在二次侧,二次侧的电流将会发生畸变,总畸变率将达到50%左右。
This paper studies the harmonic problem of electric vehicle charger in the working process.By simulating the simulation model of charging equipment,the influence of charging equipment on the power quality of local grid is simulated.The simulation results show that in the transformer The power supply side is hardly affected by the load of the charging device.The main influence of the charging device is on the secondary side,and the current on the secondary side will be distorted,and the total distortion rate will reach about 50%.
