Abstract

The invention discloses a kilowatt class off-grid and grid-connection direct drive permanent magnet wind generating set. The wind generating set comprises a wind wheel unit, a transmission and generating unit, an engine room supporting unit and a generating control output unit; the wind wheel unit comprises a blade and a hub; the transmission and generating unit is a permanent magnet direct drive generator; the engine room supporting unit comprises an engine room rotation bottom frame, a swerving yawing mechanism, a swerving yawing bearing and a unit tower; an optimized design theory is adopted by the structure of the whole machine, the set is more reliable and stable and safer, is convenient to transport and arrange, and can become middle unit wind generating equipment in all areas with wind power resources; and a single independent power supply station can be built or a plurality of units are networked so as to build an independent wind power station.

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...
