摘要

绍国家相关标准中对于电网谐波的要求和计算方法，对电网谐波的影响因素进行说明。结合某厂家生产的电动汽车直流充电桩谐波监测数据，对直流充电桩接入电网后产生的谐波进行了分析。针对不同的公共连接点最小短路容量和供电容量，研究了允许接入电网的最大直流充电桩数量，为电动汽车充电桩规模的合理配置提供了相应的理论依据。

Abstract

To study the impact of electric vehicle DC chargers on the power grid harmonics

the influence factors of grid harmonics are discussed

according to the national standard.With the observed data of a specific DC charger

the harmonic current is analyzed when the DC chargers were integrated into the power grid.The maximum number of DC chargers is studied

taking the different minimum short circuit capacity and power supply capacity of points of common coupling into account.This work provides theoretical basis for the configuration of electric vehicle DC chargers.
