Wind generating set

Abstract

The invention provides a wind generating set which comprises an impeller, a main transmission system and a power generator, wherein the main transmission system is driven by the impeller to rotate; the power generator is connected with the main transmission system; the wind generating set further comprises two different types of energy storage devices capable of storing wind energy or releasing energy to the main transmission system; the first type of energy storage device of which the rotational inertia can be adjusted is composed of a slide bar and a pouring weight; the second type of energy storage device is composed of a motor and control device thereof and a gear transmission device which are connected; the main transmission system comprises a gearbox; the gear transmission device is meshed with a gear in the gearbox. According to the invention, the cut-in wind speed is reduced, and the cut-out wind speed is accelerated, the requirement of a machine type for the wind speed is lower, the application range of a wind machine is wider, wind resources can be fully utilized, the generating capacity is increased, and the power generation time is extended.

Description

technical field [0001] The invention relates to a novel wind power generator set, in particular to a wind power generator capable of storing energy and an energy storage method for the wind power generator, belonging to the technical field of wind power generation. Background technique [0002] Whether the existing wind turbines are doubly-fed, full-power, or direct-drive, they require that the wind speed be within a certain range to work normally and generate electricity. They all have requirements for the minimum wind speed, which is the cut-in wind speed; they also have requirements for the maximum wind speed, which is the cut-out wind speed. Only when the wind speed is between the cut-in wind speed and the cut-out wind speed, the wind turbine can generate electricity normally. This will result in low power generation of wind turbines, long downtime, and low utilization rate of wind energy, which in turn will result in low profit margins of wind turbines and limit the dev...

They all have requirements for the minimum wind speed, which is the cut-in wind speed; they also have requirements for the maximum wind speed, which is the cut-out wind speed. Only when the wind speed is between the cut-in wind speed and the cut-out wind speed, the wind turbine can generate electricity normally. This will result in low power generation of wind turbines, long downtime, and low utilization rate of wind energy, which in turn will result in low profit margins of wind turbines and limit the development of the entire wind energy industry.
