摘要
提出一种基于改进型重复控制和传统PI控制的光伏并网复合控制策略,重复控制器用来减小并网电流的稳态误差,传统PI控制用来提高系统的动态性能。为验证提出的算法,搭建了基于TMS320F2812的单相光伏并网逆变系统实验模型。实验结果表明,提出的算法能够减少并网电流谐波,同时系统兼顾了良好的动静态性能。
A synthesized control scheme combined an improved repetitive control with PI control for single grid-conneeted inverter is introduced.Repetitive control is used to reduce steady-state grid-connected current wave distortion and PI control can improve the dynamic performance of the system.Simulation and experimental prototype for a single-phase grid-connected inverter controlled by TMS320F2812 are presented to verify the performance of the proposed control approach,The results prove that the harmonics in the inverter＇s output current can be effectively eliminated as well as the system can achieve good steady-state and dynamic performance with the synthesized control approach.
