Wind collecting vertical type wind power generating system

Abstract

The invention relates to a wind collecting vertical type wind power generating system which comprises a wind power system, a vertical type speed increaser, a vertical type generator and an excitation grid-connected control system, wherein the wind power system is connected with the speed increaser and the generator by a chain coupling; the generator is controlled by the excitation grid-connected control system; the wind power system is in a box frame structure and comprises a fan blade system and a wind collecting and protecting system; the upper end and the lower end of a box frame are respectively provided with an upper shed top and a lower shed plate; the wind collecting and protecting system comprises a plurality of wind collecting plates which are distributed at four sides of the box frame and hydraulic drive equipment; the upper shed top, the lower shed plate and the wind collecting plates are connected to form a wind tunnel box type wind collecting body; the generator works in a multi-winding pole-changing control way; and the generator and the speed increaser are installed on the ground. The invention has the advantages of small size, low installation, maintenance and transportation cost, high wind power utilization ratio and wind field land utilization ratio, stable performance, high storm wind resistance and favorable power generating quality and grid-connected performance, can form a high-power wind power generator unit system and is suitable for various weather and geographic environments.

Description

technical field [0001] The invention relates to a vertical wind power generation system in the technical field of wind power generation. Specifically, it relates to a novel high-efficiency wind-collecting vertical wind power generation system. 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 weigh hundreds of tons, if the tower is used to support it at a high altitude, the wind blowing will generate a huge overturning moment, which cannot be resisted. Blown by strong winds and damaged by freezi...

Problems solved by technology

For example, the existing airfoil blades have small wind-receiving area, low wind utilization rate, large wind resistance on the front airfoil, large reversing dead angle, low wind utilization rate, and difficulty in increasing the capacity

[0003] After searching the literature of the prior art, it was found that the wind blades in the wind turbines recorded in the patent documents of Patent No. ZL200430067146.5 and Patent Publication No. WO2007 / 140397A2 still have low wind power utilization rate, and there is a problem of start-up and rotation during start-up and rotation. The problem of large dead angle and reversing dead angle

[0004] Similarly, the fan blade system of the wind power generator involved in the invention patent of the patent application number 200410023530.4 adopts the NACA0009 airfoil. The wind blade has a small wind receiving area and a low wind utilization rate. There is a commutation dead angle, and it is difficult to increase the capacity
