Research on Three-phase Photovoltaic Grid-connected Inverter Based on Quasi PR Control Method
摘要
Abstract
The control method of photovoltaic grid connected inverter is the key to realize the smooth grid connection of the photovoltaic system.In order to improve the quality of grid connected current and reduce the interference of grid harmonics to the power grid,LCL type three-phase photovoltaic grid con-nected inverter circuit is selected.A quasi PR double loop control method based on grid connected current and capacitive current in grid connected control method is used.At the same time,grid voltage feed-for-ward compensation is introduced and combined with SVPWM.The simulation results under MATLAB/Simulink show that the control method can achieve no static difference tracking of fundamental sine wave and improve the stability of the system.It is of great significance to the actual operation of photovoltaic grid connected power generation system.关键词
