Air compression energy storage wind power generation method and generating set thereof

Abstract

The invention discloses an air compression energy storage wind power generation method and a generating set thereof for overcoming the rotation rate limitation and the problems of a rigid drive system in the prior art. The air compression energy storage wind power generation method comprises the following steps: 1, wind wheels convert the kinetic energy of wind into mechanical energy; 2, the wind wheels drive an air compressor to work so as to generate compressed air; 3, an air storage tank stores the compressed air; 4, the compressed air drives an air motor or a steam turbine; 5, the air motor or the steam turbine drives the generator to generate electricity; and 6, the surplus electric energy is stored. The invention also provides an air compression energy storage wind power generating set and a surplus electric energy storage device. The air compression energy storage wind power generating set comprises wind wheels, a speed increasing gear case, an air compressor, an air storage tank, an electric control valve, an air motor or a gas turbine and a generator. In the surplus electric energy storage device, the wind wheels and the speed increasing gear case of the air compression energy storage wind power generating set are replaced by electromotors, and other parts are the same as those of the air compression energy storage wind power generating set.

Description

technical field [0001] The present invention relates to a wind power generation method and a power generation device using wind energy, more precisely, the invention relates to an air compression energy storage wind power generation method and a power generation device. Background technique [0002] Wind power generation is the fastest-growing technology and device in the field of new energy and renewable energy, with an annual growth rate of 35%. For example, Germany, Denmark, and Spain are the countries with the best use of wind energy. In Germany, wind power accounts for 3% of the total electricity, Denmark more than 10% of the total electricity. By the end of 2007, the world's cumulative wind power generation will reach 83 million kilowatts, of which 58 million kilowatts are in Europe. my country's wind energy reserves are 3.2 billion kilowatts, and the developed installed capacity is 250 million kilowatts. The country has accumulatively installed 200,000 small wind tur...
