Embodiment Construction

[0030]If the newly developed and designed booster pressure storage wind turbine is matched with a 3 MW variable power generator, in order to ensure the output power of wind power generation is 3 MW, four booster pressure storage wind turbines with a rotor diameter of 60 meters are used in parallel. use. The output power of each wind wheel is 650 kilowatts, plus the automatic booster, the output power of each wind turbine is 650 kilowatts×120%=780 kilowatts. Four wind turbines are connected in parallel, and the total output power can reach 780×4=3120 kilowatts. That is: 3.12 megawatts can fully meet the needs of 3 megawatts of variable power generators. With the help of the booster, the wind wheel can start to drive the main shaft to rotate if there is a wind speed of 1 m / s. Through the speed-up of the main shaft itself (the main shaft is designed and manufactured with a 12-fold speed-up device). Then drive the air pump to work, and the air pump is completed by two parts: ax...

Abstract

The invention relates to a gas pressure storage type wind turbine with an automatic assisting device, which can supply strong high-pressure gas energy for generators, tunnel works, mining and oilfield negative-pressure oil pumping. The large turbine of the existing wind turbine is driven mostly by strong wind so as to directly drive the generator to generating electricity via mechanical speed change and speed regulation. Problems existed includes that the start-up wind speed is high, low wind speed and rated external wind speed result in reactive power so as to obtain large wind power loss, constant speed is hard to realize on a mechanical speed change and regulation device so as to result high manufacturing cost, aloft work and maintenance is difficult with high costs. The automatic assisting device is utilized in the gas pressure storage type wind turbine, thereby the start-up wind speed is lowered more, the gas pressure storage type wind turbine can be used at areas of strong and small winds, and the utilization rate of wind power can be increased to the utmost extent. As the structure is simple, large turbines and mechanical speed regulating devices can be saved, the manufacturing technique can be simplified, the total national production can be realized, the cost can be reduced, one single turbine with tens of megawatts of wind power can be realized, and thereby a novel way for wind power industry can be opened up.

Description

1. Technical field: [0001] The invention relates to an air storage pressure type wind machine capable of automatic boosting, which uses the stored high air pressure to provide a powerful high-pressure air pressure source for generators, mine exploitation, tunnel operations, oil field negative pressure pumping, etc., and at the same time can realize The generating power of a single generator reaches tens of megawatts. 2. Background technology: [0002] Current wind turbines mainly provide rotational power directly for generators. Convert wind energy into rotating mechanical energy, and then drive the generator to generate electricity and convert it into electrical energy. Another form is to convert wind energy into mechanical energy, and then into hydraulic energy, which is converted into electrical energy by a hydraulic motor. It has the following problems: [0003] 1. Both types of wind turbines can only provide rotational power for generators, using a single. [0004] ...
