In the discourse,the characters of wind generator are introduced briefly,while parameters and types of wind generators are also narrated. Base on these
3、 , the theory and constitution of the wind generator are meticulously analyzed. Firstly, Has carried on the design to wind-driven generators overall mechanism, And has designed the regulating control system. What I design is one kind of new vertical axis small wind-driven generator, by the air blowe
4、r impeller, the column, the crossbeam, the gearshift mechanism, the engaging and disengaging gear and the generator is composed. This kind of generator has the volume to be small, the noise is small, the service life is long, the price low characteristic, suits in has the wind energy resources area
5、building crown, the supply family uses electricity, For example illumination: The light bulb, conserves energy the lamp; Domestic electric appliances: Television, radio, electric fan, washer, electric refrigerator. Key words:Wind power generation, Regulating control system, Small wind-driven generat
