摘要

在并网光伏系统中，谐波降频技术是提高电能质量的重要手段。本文主要对三相并网光伏系统中电感(L)、电感-电容(LC)、高阶LCL和LLCL滤波器的设计和分析进行了研究。讨论了100KW并网综合系统各拓扑结构的参数设计过程。为了更好地分析各滤波器的性能，对各拓扑结构中的谐波含量进行了比较。与其他滤波器相比，LLCL滤波器显示出良好的效果，最终最大限度地提高了电能质量，并将谐波失真降低了0.58%。在MATLAB/Simulink中验证了所述滤波器的工作和性能。

Analysis and Design of Passive Filters for Power Quality Improvement in 3ϕ Grid-Tied PV Systems

Harmonic reduction techniques for power quality enhancement is of prime importance when it comes to grid connected PV systems. This paper focuses on design and analysis of inductive (L), inductive-capacitive (LC), higher order LCL and LLCL filters in a three-phase grid-tied PV system. Parameters design procedure is discussed for all topologies in a 100KW grid integrated system. A comparison of harmonic content in each topology is presented to best analyze the performance of each filter. The LLCL filter shows promising results, which ultimately leads to maximum enhancement of power quality as well as reduced harmonic distortion of 0.58% when compared with other filters. The working and performance of said filters is verified in MATLAB/Simulink.
