Abstract
The invention relates to the field of power, in particular to a method for wind generation and device thereof. The method includes the steps of: firstly compressing air into an air storage container, using the high-pressure air in the air storage container to drive a turbine and achieving the wind generation by a generator driven by the turbine. An air compressing system is arranged between a blade transmission set and a generator set, namely, the kinetic energy from the rotation of the blade is converted into the compressed air by an air compressor to be stored; then the compressed air in the air storage container of the air compressor drives the generator set to rotate to achieve the generation, so that the power of generation can be stabilized greatly through the adjustment of the air outlet valve of the air storage container, the adjustment of the brake and rotary speed of the blade can be realized through the configuration of the air compressing system and the like. The air can be stored when the wind is heavy or released when the wind is light, thus the wind generation is not limited by the wind power any more.
Description
Technical field
The present invention relates to power domain, relate in particular to a kind of method and power generation system thereof of wind-power electricity generation.
Background technique
Wind energy more and more is subjected to the attention of countries in the world as a kind of renewable energy sources of cleaning.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 * 109MW, and wherein available wind energy is 2 * 107MW, and is also bigger 10 times than the water energy total amount that can develop on the earth.The Chinese feature energy storage capacity is very big, distribution is wide, and only the wind energy content of land is about 2.53 hundred million kilowatts.Along with development of global economy, wind energy market also develops rapidly.Over nearly 5 years, wind energy market, world every year is all with 40% speed increment.Estimate in the following 20-25 that wind energy market, the world will increase progressively 25% every year.Now, the wind energy power cost dropped to 1980 1/5.Along with the development of technological progress and environmental protection cause, wind energy power will can be competed with coal fired power generation fully commercial.
But adopt wind-power electricity generation also to have a lot of problems at present, maximum problem is the instability of generated output to be subjected to the restriction of wind speed very big.Simple by the also very difficult at present continued power that guarantees of wind-power electricity generation.And the generating on general daytime of traditional wind-power electricity generation is ac power supply, become DC electrical source through inverter, is stored in the storage battery, again DC electrical source become ac power supply through inverter during electricity consumption.Because storage battery cost height, the time on probation has only one to two year, scraps storage battery and also can bring environmental pollution.
Summary of the invention
The object of the present invention is to provide a kind of environmental protection, the stable not wind-engaging speed limit system of generated output, can guarantee the wind power generation method that persistency is powered.
Another object of the present invention is to provide a kind of system of wind-power electricity generation.
In order to solve the problem that exists in the background technique, the present invention adopts following technological scheme:
A kind of method of wind-power electricity generation at first is stored into air compression in the air holding vessel, promotes gas-turbine with the high-pressure air in the air holding vessel then, and gas-turbine drives generator and realizes wind-power electricity generation.
A kind of wind-power generating system, comprise gas-turbine, generator, wind-force fan blade, be connected with air compressor on the described wind-force fan blade, air compressor is connected with the air holding vessel by breather line, the air holding vessel is connected with gas-turbine, and gas-turbine drives generator.
Described air holding vessel is arranged on underground.
Existing wind power plant is the rotation realization generating that drives generator amature by the rotation of leaf fan, the present invention adds air compression system between leaf fan transmission and generator set, the kinetic energy that is about to the rotation of leaf fan is converted into pressurized air by air compressor earlier and stores, and then by the rotation of the drive of the pressurized air in air compressor gas holder generator set, realize generating, the adjusting that can cut down by gas holder the is given vent to anger power of stable electric generation greatly can also be realized the braking of leaf fan or the adjusting of rotating speed etc. by the configuration to compressed air system like this.Can storing compressed air when wind is big, discharging air generating again when wind is little, wind-power electricity generation no longer is limited by the size of wind-force!
Description of drawings
Fig. 1: wind-power generating system structural drawing of the present invention.
Embodiment
The present invention will be further described by specific embodiment below in conjunction with accompanying drawing 1.
The method of wind-power electricity generation of the present invention, by air compression being stored in the air holding vessel, the high-pressure air that will be compressed in then in the air holding vessel promotes gas-turbine, and gas-turbine drives motor and realizes wind-power electricity generation then.
Present embodiment provides a kind of wind-power generating system, this system comprises gas-turbine 6, generator 7, wind-force fan blade 1, described wind-force fan blade 1 is connected with air compressor 2, air compressor 2 is connected with air holding vessel 4 by breather line 3, air holding vessel 4 is connected with gas-turbine 6, and gas-turbine 6 drives generator 7 and realizes wind-power electricity generation.
Can also connect air compressor and gas-turbine by breather line at the underground air holding vessel 5 that is provided with.
The adjusting that can cut down by gas holder the is given vent to anger power of stable electric generation greatly can also be realized the braking of leaf fan or the adjusting of rotating speed etc. by the configuration to compressed air system like this.Can storing compressed air when wind is big, discharging air generating again when wind is little, wind-power electricity generation no longer is limited by the size of wind-force.
