用于光伏发电系统的LLCL型滤波器混合阻尼控制策略
Hybrid Damping Control Strategy for LLCL Filters of PV Systems
摘要
Abstract
In order to make the photovoltaic (PV) system meet the standards on grid-connected current harmonics,an LLCL filter-based inverter is developed with a hybrid active and passive damping control strategy.By setting the parameters of the hybrid damping scheme properly,the advantages of passive and active damping controls are combined and made full use.Finally,the presented control scheme is simulated by the program of Matlab/Simulink,which shows that the LLCL filter with a hybrid damping control scheme can not only attenuate the harmonics around the switching frequency and reduce the inductance of the grid side,but also demonstrate its good filtering capability to guarantee the grid-connected current harmonics complied with the related standards.关键词
