Aerogenerator with movable stator

Abstract

The invention discloses a wind turbine generator with movable stator, and belongs to wind turbine generator. The invention comprises a bench (1), a wind wheel (2), a low speed axle (3), a gear box (4), a high speed axle(5), a generator rotor (6), a generator stator (7), a slide rail (8), a slide vane (9), a connecting rod (10), a slide vane regulator (11) and a wind speed sensor (12). The generator stator and the slide vane are fixed, with position in the slide rail regulated by the slide vane regulator according to the wind speed signals detected by the wind speed sensor. Part of the stator winding coils participate the rotary cutting of the generator rotor when the wind speed is normal; when wind speed increases to the high wind speed condition, the position of the generator stator is regulated through the connecting rod and the slide vane by the slide vane regulator to increase the number of stator winding coils which participate the rotary cutting of the generator rotor, and thereby increasing generation power, and maintaining a low level of the wind wheel rotation speed. The invention has the advantages of high utilization efficiency of wind energy, excellent regulation capacity and good security.

Description

technical field [0001] The invention relates to a wind power generator with a movable stator, which belongs to the technical field of wind power generators. Background technique [0002] As the most mature renewable energy technology, wind power generation is a practical solution to the imminent natural environment and social crisis caused by the massive use of traditional fossil fuel energy. All over the world, wind power generation is developing rapidly and continuously. In the past 20 years, the maximum power of a single wind turbine has changed from tens of kilowatts to 2,500 kilowatts today, and is moving towards 5,000 kilowatts for a single machine. The goal is moving forward. The power of wind farms using multiple units connected to the grid for power generation can reach hundreds of thousands of kilowatts, and has become an important part of the energy supply chain, rather than a dispensable supplementary energy source. my country has a vast territory and is rich in...

Problems solved by technology

However, the common problems of the above methods are that the structure is complex, the adjustment ability is limited, and due to the constraints of materials, manufacturing technology and control methods, the generator blades will have to be stalled under high wind speed conditions, even if the generator stops. work, which wastes a lot of high-efficiency wind energy
