Description

technical field

[0001] The invention belongs to the field of wind power generation and new energy. The invention relates to the technology of kilowatt-level wind power generators, that is, the technology of medium-sized wind power generators, and in particular to the technology of kilowatt-level off-grid and grid-connected direct-drive permanent magnet wind power generators. Background technique

[0002] The reduction and price increase of conventional energy, the increasing destruction of the environment in which human beings live, and the impact of the greenhouse effect have awakened people and governments all over the world to pay attention to environmental protection. The proportion of developing new energy sources in energy is increasing year by year, and wind power generation has developed into a new industrial industry and a new economic growth point. The large-scale wind power generation technology in the economically developed countries in the world is at the forefr...
