摘要
介绍了电动汽车能源供给设施,从谐波构成和谐波时空分布的角度分析不同充/换电设施充电电流谐波的特点,并根据其特点制定合理的谐波治理措施。搭建Matlab模型对有关方案进行仿真。仿真结果表明,治理后谐波含量大幅降低,满足电能质量要求,所提方案可为充/换电设施的谐波治理提供参考和依据。
The existing main energy supply infrastructures of electric vehicles （EVs） were introduced and the harmonic characteristics were analyzed in the respect of harmonic component and its temporal and spatial distribution, the technical measures for restraining the harmonics were raised. By using Matlab as a tool, models for harmonic control methods were simulated. The results show that the suppression methods are valid and the power quality requirement can be well met, which provides a feasible reference for the actual suppression work.
