摘要
为了提出合理的电动汽车充电站谐波抑制方法,对采用有源电力滤波器、十二脉整流以及PWM整流三种谐波抑制方法的充电站进行分析比较。首先根据充电机原理和主要的谐波抑制方法建立了相应的充电机和充电站模型,通过仿真分析三种模型的谐波含量和功率因数,根据仿真结果、使用性能及经济性方面分析三种方法的优缺点,最后提出这三种充电站谐波抑制方法的改进措施和发展方向。分析表明,带有LC滤波器的十二脉整流方式可以用于抑制充电站谐波;带有LC滤波器的APF补偿方式更适合充电站谐波抑制,将是未来一段时间内常用的充电站谐波抑制方法;PWM整流方法将随着使用成本的降低而成为电动汽车充电站谐波抑制的最终方式。
In order to propose reasonable method of harmonic suppression for EV charging station, three methods that are 6-pulse rectifier with APF, 12-pulse rectifier, and PWM rectifiers are analyzed and compared. Firstly, the corresponding simulation model of charger and charging station are built based on the principle of EV charger and the main methods of harmonic suppression. Then the harmonic content and power factor for different simulation models are researched. At the same time, the advantages and disadvantages of different simulation models are studied according to the results of simulation, the use of performance and economy. At last, the improvement measures and development direction for three methods are proposed. The result shows that 12-pulse rectifier with LC filter can be used to suppress the harmonic of charging station; APF compensation with LC filter is more suitable for that and it will be a universal one for a period of time; PWM rectifier will be the ultimate way for that when the cost of it becomes lower.
