Control Strategy Review of Small Wind Power Grid Inverter
摘要
Abstract
Analysis and comparisons of various control strategies were carried out ,to improve the grid-connected performance of small scale wind power generation system,while the two stage grid connected inverter was taken as an object. Starting from control objectives inverter system needs to achieve ,the analysis were carried out on the existing three overall control strategy. For wind energy maximum power point tracking(MPPT)control,the maximum wind energy capture method and the maximum power output were given,the difficulties in the maximum wind energy capture method in practical application were pointed out,the maximum power output method was focused on. Because DC-link voltage and grid current control are key links for the entire wind power system ,its various control strategies were emphatically discussed,its advantages were analyzed and the improvement plan was put forward. Grid connected filter was as an effective method to improve the quality of grid connected power ,its function and classification were briefly discussed. Finally,the development trend of small wind power system two levels of grid inverter control strategies were presented.关键词
