Abstract

The invention relates to a generator, in particular to an electronic variable power and variable speed wind power generator, which changes the power according to the wind power. The wind power generator comprises the generator, a main shaft, a shaft coupling, a rectification device, a sensor, and a plurality of generator units, wherein, the main shaft of each generator unit is connected by the shaft coupling, each generator unit is provided with the rectification device, and each rectification device is connected with a reversal relay; and the end of the generator is provided with the sensor. The invention replaces the original given power and given voltage generator by the electronic variable power and variable speed wind power generator which is applicable to the areas with changing wind speed, and more suitable for use at sea, and has the advantages of long on-line time, high wind energy utilization rate, less additional equipments, saving investment, long use life, simple operation and convenient use.

Description

technical field

[0001] The invention relates to a generator, in particular to an electronically variable power and variable speed wind power generator that changes power according to the wind force. Background technique

[0002] Wind power is one of the current green energy sources for energy saving and emission reduction. At present, most of the wind turbines in production and operation in our country are products imported from foreign equipment, foreign technology or Sino-foreign joint ventures. Most of the equipment produced in the early stage was fixed propeller, constant speed gearbox, and constant power generator. This product cannot adjust the speed when the wind speed is variable. When the wind is strong, the wind generator will overspeed, causing the blades to break and the generator to be damaged. Burned out; the later products adopt blade tip reverse speed regulation, its structure is complicated, which increases the load on the blade and reduces the life of the ...
