Abstract

The invention belongs to the technical field of wind generation, particularly relates to a wind turbine set, aims to solve the problems of low wind energy utilization rate and low power generation efficiency when conventional wind turbines work in areas with complex wind conditions and discloses the wind turbine set. The wind turbine set comprises an outer energy collecting barrel, a bearing base,an anti-direction dual-rotor motor, a resistance type impeller and a lift type, wherein the anti-direction dual-rotor motor is located between the outer energy collecting barrel and the bearing base;the resistance type impeller is vertically arranged, the upper end extends into the outer energy collecting barrel, the lower end extends between the outer energy collecting barrel and the bearing base, and the resistance type impeller is connected with an outer rotor of the anti-direction dual-rotor motor; the lift type impleller is located above the resistance type impeller and connected with an inner rotor of the anti-direction dual-rotor motor; the resistance type impeller and the lift type impeller rotate in opposite directions. Secondary utilization of wind energy can be realized and the wind energy utilization rate and the generation efficiency can be improved by means of the wind turbine set.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generating set. Background technique [0002] With the continuous development of renewable clean energy, the utilization of wind energy has reached a new height. Among them, through the early distributed development of offshore wind power and onshore wind power, high-quality wind farms have basically been utilized, forcing the subsequent development of wind power to shift to areas with more complex wind resources. In this way, wind turbines are not only required to face more complex wind conditions, but also the technical requirements for wind energy utilization are getting higher and higher. [0003] At present, conventional wind turbines need to face the incoming wind when generating wind power, so as to absorb incoming wind energy to the greatest extent and improve the power generation efficiency of the wind turbine. However, for areas ...
