摘要
为了滤除由分布式系统产生的谐波,LCL型滤波器较L型滤波器和LC型滤波器有体积和成本的优势,并且能够对高频谐波有更好的抑制作用,成为研究分布式发电系统并网的研究热点之一。本文通过对LCL型滤波器建立数学模型,详细分析其工作原理及其特性,并针对其谐振问题,讨论了无源阻尼和有源阻尼的谐振抑制方法,提出一套实用的参数设计方法.最后通过MATLAB/Simulink仿真软件搭建模型,对相关理论和方法的可行性进行验证。
In order to filter harmonics generated by the distributed system, comparing with L type fil- ter and LC type filter, LCL type filter become one of the research hotspots in grid connected distribu- ted generation system, because of its volume and cost advantages, and better inhibitory effect on high frequency harmonic. In this paper, by establishing the mathematical model of LCL type filter, its working principle and characteristics are analyzed in detail, and a set of practical design method of the parameters is put forward; and the resonant suppression methods of passive damping and ac- tive damping are discussed. Finally, through MATLAB/Simulink simulation software, the model is built, and the feasibility of the relevant theories and methods are verified.
