Generator set applicable to low-speed wind power and high-speed wind power

Abstract

The invention relates to provide a generator set applicable to low-speed wind power and high-speed wind power. The generator set comprises a wind turbine, a clutch, a low-speed permanent magnet wind generator and a high-speed permanent magnet wind generator. The clutch comprises a hollow gear, a solid gear and a hollow gear shaft, a first steel plate and a second steel plate are installed at the upper end and the lower end of the hollow gear shaft respectively, a first electromagnet, a first spring and a first armature are sequentially installed on the outer side of the first steel plate, a second electromagnet, a second spring and a second armature are sequentially installed on the inner side of the first steel plate, the inner side and the outer side of the second steel plate are of the same structure as the inner side and the outer side of the first steel plate, the inner wall of the hollow gear is located on the outer side of the first armature and the outer side of a third armature, and the solid gear is located below the hollow gear. The wind turbine is connected with the hollow gear shaft. A shaft of the low-speed permanent magnet wind generator is installed between the second armature and a fourth armature. A shaft of the high-speed permanent magnet wind generator is installed in the solid gear. The generator set can be operated normally at a low speed and at a high speed.

Description

technical field [0001] The invention relates to a power generating device, specifically a wind power generating device. Background technique [0002] Wind turbines are in a natural environment, and the wind speed changes frequently and in a large range. The wind turbines currently in operation are equipped with a cut-out wind speed, that is, the wind turbines that exceed this wind speed will be cut off from the power grid, and the control system will take normal shutdown for protection. Otherwise, it will often It will cause the generator to overspeed, overheat and cause failure. In order to ensure the long-term normal operation of the wind turbine, overspeed and overheating protection devices must be installed on the wind turbine. But at present, the existing wind turbine overspeed protection generally adopts multiple instantaneous electric short-circuit braking devices. However, in the state of strong wind, high speed of wind rotor and large rotational torque, sudden inst...
