电动汽车充电站中谐波相互抑制的研究
Research of Mitigating Harmonic by Harmonic in Electric Vehicle Chargers
摘要
Abstract
In order to mitigate harmonic by harmonic current for the maximum possible in charging sta- tion, a simulation model of chargers is established to study the influence that the output power of charger and the mode of transformer connection have on the harmonic current phase. The results of simulation in- dicate that the bigger the difference of the output power of charger is, the bigger the difference of harmonic current phase is, and that the type of transformer connection has more influence on the harmonic current phase of the high voltage side. Based on the conclusion, the method that increases the gap of the output power of chargers is put forward to achieve the harmonic suppression for the maximum possible between chargers; When two transformers (the connection type are Yy0 and Yd11)are linked to a same bus bar to supply power for two groups of chargers, the most of the 5th, 7th harmonic current produced by 6 pulse rectifier charger can be mitigated at power source. And the closer the output power of chargers is, the bet- ter the effect of harmonic suppression is.关键词
