Abstract

A multi-winding variable-pole variable-speed vane-type vertical wind power generating system relates to a vertical wind power generating system. In order to solve the problems that the conventional wind power generator has poor running performance, low wind utilizing ratio, and inconvenient assembly, maintenance and transportation, three schemes are provided; a first scheme is as follows: a vertical generator is a multi-winding variable-pole vertical asynchronous generator; a fan support has a frustum-shaped structure; the vertical generator is arranged on the fan support, connected with a vertical speed increaser and controlled by an exciting intelligent grid-connected control system; the lower end of a vertical crankshaft is connected with the vertical speed increaser through a shaft coupler; an electromagnetic brake is installed on the lower end surface of an upper frame and sleeved on the vertical crankshaft; a single vane of a vane system has a vertical shutter structure; a second scheme is as follows: the single vane of the vane system has a transverse shutter structure; and a third scheme is as follows: the single vane of the vane system has a streamline structure. The multi-winding variable-pole variable-speed vane-type vertical wind power generating system is applied to wind power generation.

Description

technical field [0001] The invention relates to a vertical wind power generation system, in particular to a multi-winding vertical wind power generation system with pole-changing and speed-changing fan blades, belonging to the technical field of wind power generation. Background technique [0002] With the occurrence of the world energy crisis, the use of wind kinetic energy as a new energy source has become a hot spot in the development of modern society. The generator set and the speed increaser of the traditional three-bladed wind turbine are installed high above the top of the tower, and the long and heavy wind blades are hung obliquely on the side, which requires a heavy counterweight. Considering that the wind blades, speed increaser, generator set, counterweight and the heavy engine room have a weight of several hundred tons, they are supported at high altitude by the tower, and when the storm blows, a huge blowing and overturning moment will be generated, which is ea...
