Abstract
Grid current control technology not only affect the quality of grid inverter current,but also is the key to the successful interconnection of the grid inverter technology. So a well-performed grid current control strategy is needed urgently. By establishing a mathematical model of grid inverter,grid current problems were analysed such as steady?state error and the disturbance in the grid inverter under the proportional integral(PI)control. Base on those problems presented above,two grid current control strategy,one cycle control and quasi resonant PR control,were proposed. The three kinds of control strategies in grid current control performance were compared through Matlab simulation. The simulation and experiments results show that the control performance is superior by using a quasi resonant PR controller.关键词
