摘　　要：在政府对电动汽车产业的大力推动下,我国电动汽车产业将步入快速发展期,这也极大地推动了电动汽车充换电设施的建设。大量充电设备的接入将给电网的电能质量带来影响。文中以某电动公交充换电站为依托,通过大量现场试验取得详尽的数据,分析不同规模充电机对电网造成的谐波影响,并对采用谐波治理措施的效果进行测试和评估。采用有源电力滤波器后网侧5、7次谐波电流明显减少,满足国标GB/T 14549-2008规定的限制值。Under the vigorous promotion by the government, electric vehicles （EV） enjoy a rapid growth period in China, fueling the large-scaled construction of charging facilities. The harmonic currents caused by EV chargers, however, may have significant impacts on power grids. This paper presents the test results of a battery^xchange ＆ charging station for electric buses and analyzes the harmonic pollutions caused different sizes of chargers. Finally, the effects of harmonic control measures are tested and evaluated. The test results show that the 5th, 7th harmonic currents can be effectively suppressed with the filter installed; reaching the limited value stipulated in the GB/T 14549-2008.
