摘要

针对现有三相交流充电桩LCL滤波器投运后不能达到理想的滤波效果

滤波电容甚至会被严重损害这一问题

本文研究了电网背景下三相交流充电桩LCL滤波器的交互影响。论文首先基于三相交流充电桩的电气拓扑和谐波产生机理对LCL滤波器进行参数设计并得出最优阻尼电阻

接着通过研究背景谐波源、同级谐波源以及多台充电桩之间的交叉耦合效应的等效模型建立了评价函数

最后通过仿真得出交叉耦合效应对LCL滤波器的影响

以期对三相交流充电桩LCL滤波器的优化设计提供借鉴。

Abstract

In view of the issue that the existing three-phase AC charging pile LCL filter cannot achieve ideal filtering effectand even damage seriously after operation

in this paper

the interaction of three-phase AC charging pile LCL filter in the grid background is studied.Firstly

the parameter design of three-phase AC charging pile is performed based on the electrical topology and harmonic generation mechanism of three-phase AC charging pile and the optimal damping resistance is obtained.Then

the evaluation function is established by studying the equivalent model of the background harmonic source

the same harmonic source and the cross-coupling effect among multiple charging piles.Finally

the influence of interaction influence on the LCL filter is obtained through simulation

which can provide reference for the optimization design of the three-phase AC charging pile LCL filter.
