Automatic direction-regulating type permanent-magnet direct-drive wind driven generator

Abstract

The invention provides an automatic direction-regulating type permanent-magnet direct-drive wind driven generator, and relates to the technical field of wind driven generators. The automatic direction-regulating type permanent-magnet direct-drive wind driven generator comprises a power generator, wind wheels, a wind speed and wind direction measurer, a sensor, a controller and a storage battery, wherein the power generator is arranged on a platform at the upper end of the bracket; the two sides of the power generator are separately provided with a bearing base; a horizontal type main shaft is arranged on the bearing bases; the two end parts of the horizontal type main shaft are fixedly provided with wind wheels, and the wind wheels are of Senegal type structures; and a bearing is arranged between the platform at the upper end and a supporting column body. When the wind direction is not perpendicular to the horizontal type main shaft or exceeds a set value, the power generator can be in an electric state, so that the horizontal type main shaft deflects in a direction perpendicular to wind force until a perpendicular state, and the horizontal type main shaft is automatically recovered to a power generation state for generating power. According to the automatic direction-regulating type permanent-magnet direct-drive wind driven generator, the starting wind speed is low, the output torque is stable, the service life of a fan is long, the power generation efficiency is high, the structure is simple, and the space usage is less.

Description

technical field [0001] The patent of the present invention relates to the technical field of wind turbines. Background technique [0002] With the depletion of coal resources, there is an urgent need to find new clean and non-polluting energy sources to replace them in the field of power generation. Wind energy resources have the advantages of wide distribution, inexhaustible, inexhaustible, clean, etc., and have attracted the attention of scholars at home and abroad. At present, the horizontal axis fan is widely used, and the horizontal axis fan has the advantages of high utilization rate of wind energy and mature production and processing. However, due to its complex control structure, it generally requires a gearbox, a yaw system, etc., which is limited. The vertical axis fan has the advantages of simple control structure, wide operating wind speed range, low starting wind speed, simple manufacturing process, low cost, various blade types, and less noise pollution. sta...

Problems solved by technology

However, due to its complex control structure, it generally needs a gearbox, yaw system, etc., which is limited.

The control structure of the vertical axis fan is simple, it has the advantages of wide operating wind speed range, low starting wind speed, simple manufacturing process, low cost, various types of blades, and less noise pollution; however, the vertical axis fan has low wind energy utilization rate, is not easy to self-start, and is difficult to control stall

At present, these two types of fans have been extensively studied by scholars, and their respective models and ideas have been proposed, but both have limitations
