电动汽车充电站谐波特性分析与APF应用研究
|
摘要
为了抑制电动汽车充电站引起的谐波问题,在分析谐波产生的特性的基础上,选取APF对充电过程中产生的谐波进行治理。首先,指出电动汽车充电站中具有非线性特性的装置接入导致大量谐波注入到公共电网,危害电网的安全稳定运行;然后,搭建电动汽车充电机模型和含多台充电机的充电站模型,分析充电站内谐波电流的特性;提出采用APF装置对充电过程所产生的谐波进行抑制,并具体设计了指令电流运算电路和补偿电流生成电路。最后,通过Matlab仿真算例验证了所提治理措施的可行性和有效性。
In order to suppress the harmonic problem caused by electric vehicle charging station,the characteristics of harmonic generation are analyzed,and APF is selected to control the harmonics generated in the charging process.Firstly,it is pointed out that a large number of harmonics are injected into the public power grid due to the non-linear devices connected to the charging station of the electric vehicle,which endangers the safe and stable operation of the power grid.Then,the electric vehicle charger model and the charging station model with multiple chargers are built to analyze the characteristics of harmonics current in the charging station,and the APF device is proposed to suppress the harmonic generated in the charging process,and the instruction current operation circuit and compensation current generation circuit are designed in detail.Finally,the feasibility and effectiveness of the proposed control measures are verified by Matlab simulation.
