Abstract

The invention relates to a wind power generation system. According to the wind power generation system, flywheels are taken as energy storage devices, a one-pole dc magnetic driver (HET) is taken as flywheel energy transmission equipment, the stable power generation function is realized, and energy transmission advantages of the HET perform; a vertical flexible flywheel and a suspension type flexible flywheel are further employed, problems of a large-mass flywheel and a bearing are solved. HET speed change transmission is employed between the flywheel and a generator to greatly improve wind energy capture efficiency. Three schemes for energy transmission among a wind wheel, the generator and the flywheel, the first scheme is a no-HET scheme between the wind wheel and the generator, namely, an energy storage device and energy transmission equipment thereof are added to a routine wind power system in the prior art, the second scheme is an independent HET scheme between the wind wheel and the generator, the third scheme is a scheme through which the wind wheel, the generator and the flywheel are respectively connected with one HET half matching part.

Description

[0001] Technical field

[0002] The invention relates to a wind power generation system, particularly a wind power generation system with an energy storage device. Background technique

[0003] Wind power is recognized as a green energy source with broad prospects. At present, the technology has been successfully applied for a long time, and the economic competitiveness of the wind power system itself is constantly improving. However, from the overall perspective of the power grid, in terms of comprehensive indicators, there are still the following problems: Due to the large instability and randomness of wind speed, the wind energy power obtained by the wind turbine is always variable in a large range, and there is no energy storage. The power generation of the installed wind power generation system is very unstable. Generally, the installed capacity of wind turbines is not regarded as a stable and reliable power generation capacity in the grid. The increase in installed capacity o...
