Direct-drive ground wind generating set for high-altitude power generation

Abstract

The invention relates to a direct-drive ground generating set for high-altitude power generation, and belongs to the technical field of high-altitude wind power generation. The ground generating set comprises a generator and brakes, rollers, clutches and motors which are arranged on two sides of the generator symmetrically, wherein two ends of one roller and two ends of the other roller are connected with the brakes; two ends of a rotor shaft of the generator are connected with the brakes at one end of one roller and at one end of the other roller; the brakes at the other ends of the rollers are connected with the motors through the clutches; when the generator generates electricity, the two rollers are connected with an aerial work doing umbrella through ropes; and the two clutches are connected with an external control part and controlled to alternately work, so that the generator generates the electricity continuously, and the generated energy of the generator is improved. The ground generating set can transmit aerial mechanical energy to the ground; and the two clutches are controlled to alternately work by the external control part, so that the generator is in a working stateall the time.

Description

technical field [0001] The invention belongs to the technical field of high-altitude wind power generation, and in particular relates to a direct-drive high-altitude ground-based wind power generating set that is easier to convert wind energy into electric energy. Background technique [0002] my country is a country with large wind energy resources, but few people have noticed that our country is also a country with high-altitude wind energy. Current wind energy utilization is limited to the low altitude of tens of meters to hundreds of meters. However, at altitudes ranging from a few thousand meters to 10,000 meters, not only the wind speed is stronger, but also the wind force is stable. Less than 5% of the year's time without wind blows. Experts generally believe that high-altitude wind energy is hundreds of times more than ground wind energy, and construction of aerial wind power plants can be considered. It is understood that at present, the wind density of the most a...

The current utilization of wind energy is limited to the low altitude of tens of meters to hundreds of meters

However, at altitudes ranging from a few kilometers to 10,000 meters, not only the wind speed is greater, but also the wind force is stable. The time of no wind blowing is less than 5% of the year.

The problem with this structure is that the transmission chain is designed on the airbag, which will undoubtedly increase the weight of the airbag and increase the safety hazard in the air. Moreover, the power generation efficiency of this structure is relatively low, which cannot meet the requirements of power generation, and not only wastes a lot of wind power resources, but also wasteful from an economic profit point of view
