Variable capacity small wind power generation device and method thereof

Abstract

The invention discloses a variable capacity small wind power generation device and a method thereof. The wind power generation device comprises a front generator, a disc friction clutch, a centrifugal clutch, a rear generator, a main shaft, blades and supporting structures of the blades. A front friction disc and a rear friction disc of the friction clutch are fixed to the front generator and a blade hub respectively, a throwing block and an outer cup of the centrifugal clutch are fixed to the main shaft and the rear generator respectively, only the friction clutch is engaged under the low wind speed condition, at the moment, the front generator generates electricity, as the wind speed increases, axial force and centrifugal force, borne by the blades and the supporting structures of the blades, increase, accordingly friction clutch is separated, meanwhile the centrifugal clutch is combined, and the rear generator starts to generate electricity. The wind power generation device is independent of a servo system, automatically adapts to a large wind speed range at low cost and can continuously operate, and improves wind energy use efficiency.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a variable-capacity small wind power generating device and a method thereof. Background technique [0002] Small wind turbines are generally composed of wind rotors, generators (including devices), steering devices (tail fins), towers, speed limit safety mechanism energy storage devices, and inverters. The generator is composed of nose, swivel, empennage, and blades. The functions of each part are: the blades are used to receive wind force and convert it into electrical energy through the nose; The nose can be rotated flexibly to realize the function of adjusting the direction of the tail; the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic field line to generate electric energy. The wind turbine is unstable due to the wind volume, so the wind turbine generally has a wind wheel, a generator (including device), steering device (tail), tower, spee...

Problems solved by technology

However, due to the lack of corresponding speed regulation and control mechanism, the operating range of the wind speed of the existing small wind turbines is not wide enough, and the wind energy of various wind speeds cannot be fully utilized.
