Abstract

The invention discloses a wind turbine driving mechanism and a wind turbine comprising the drive mechanism. One embodiment discloses the wind turbine driving mechanism. The mechanism comprises a rotorshaft, a primary driving mechanism and a secondary driving mechanism, wherein the primary driving mechanism is connected with the rotor shaft, and the secondary driving mechanism is connected with the primary driving mechanism. According to the provided wind turbine driving mechanism, the above structure is adopted, so that the mechanism is high in wind energy conversion efficiency and high in power generation efficiency.

Description

technical field [0001] The invention relates to a wind turbine drive mechanism and a wind turbine comprising the drive mechanism. Background technique [0002] A wind turbine is a turbine powered by wind energy. A wind turbine is like the air intake of a jet engine. As air enters, it first encounters a fixed set of blades, known as a stator, which directs the air into a set of rotating blades - the rotor - where the air moves faster than it can flow outside the turbine. Slow, the shroud is shaped so that it directs the relatively fast-flowing air on the outside into the area behind the rotor, the fast-moving air accelerates the slow-moving air, causing the area behind the turbine blades to become low pressure to absorb More air passes through them. [0003] In large turbines, the rotor speed is limited by the allowable tip speed of the blades, therefore, the longer the blades, the slower the rotor speed and the power captured is proportional to the square of the diameter o...
