Abstract: Concentrated wind energy generator uses concentrated equipment to turn rare and unstable wind into equal wind. 200W Concentrated wind energy generator has been applied in many regions in Japan and China. When natural wind speed of 200 W concentrated wind energy generator was 10 m/s, the efficiency of turbine was 0.603, power of system reached 208.6W, coefficient of wind energy utilization of 200 W concentrated wind energy generator was 0.52 and the turbine worked well. Compared with some other excellent power systems, the 200 W concentrated wind energy generator had short diameter, low start wind speed and high coefficient of wind energy utilization characteristics, which has wide application prospect.
