摘要
针对中山乐群电动汽车充电站存在谐波电流畸变率较高,5、7、11、13次谐波电流超标的问题,从理论上分析了电动汽车充电机工作时产生谐波电流的机理,提出加装并联型有源电力滤波器(active power filter,APF)的谐波治理方案。对加装APF前后的谐波电流含有量测试结果进行对比,发现谐波治理后电流畸变率明显减小,各次谐波电流含有量达到国家标准的要求。测试结果说明该谐波治理方案有效、可行。
In allusion to problems of high distortion factor of harmonic current and harmonic current exceeding in Zhongshan Lequn electric vehicle charging station,this paper analyzes mechanism of producing harmonic current of electric vehicle charger in theory and proposes treatment scheme for harmonic control of installing paralleled active power filter（APF）. Comparison of testing results of harmonic current contents before and after installing APF was carried out and it was discov-ered that distortion factor of current after harmonic controlling obviously decreased and harmonic current contents reached to national standards. The testing results indicates that this treatment scheme for harmonic control is effective and feasible.
