摘要
网侧滤波器是双馈变流器的重要组成部分,其参数的选择很大程度上决定了变流器的性能指标以及抗电网扰动能力,因此合理选择滤波器参数是设计变流器的重要工作。本文提出一种双馈变流器网侧LCL滤波器的设计方法,与传统的L滤波器相比,该设计可以降低电感值,提高系统的动态响应能力,同时获得更好的滤波效果。通过搭建基于LCL滤波器的双馈变流器模型进行仿真验证,仿真和实验结果证明本文所提出的LCL滤波器的设计方法是有效可行的。
The grid-side filter is an important part of the doubly-fed converter.The choice of its parameters largely determines the converter’s performance indicators and the ability to resist grid disturbances.Therefore,a reasonable choice of filter parameters is to design the converter Important work.This paper proposes a design method for the grid-side LCL filter of a doubly-fed converter.Compared with the traditional L filter,this design can reduce the inductance value,improve the dynamic response of the system,and obtain a better filtering effect.The simulation verification is carried out by building a doubly-fed converter model based on the LCL filter.The simulation and experimental results prove that the design method of the LCL filter proposed in this paper is effective and feasible.
