Embodiment Construction

[0019] It adopts the "wind collection, control, and rectification" type wind power generation system project, and its structure is 50 meters to 100 meters to 150 meters high from the flat ground. Type, etc., the frame cylinder is composed of an elevated structure as the frame, the vertical axis vortex wind turbine system and the multi-pole generator system are connected in series on the same axis, placed in the frame structure, and the membrane structure is used to "collect wind, control pressure, and rectify" When the airflow blows through the air collecting body in different forms, the airflow is blocked, and 100% of the wind energy per unit area is incorporated into the system, changing the direction of the airflow, forming high-speed, high-pressure and high-density ratio wind energy, and entering the vortex fluid. A high wind pressure area is formed in the air flow channel, and the wind energy drives the resistance wind turbine to be converted into mechanical energy, drivin...

Abstract

The invention provides an advanced flow-collecting and flow-controlling variable-pressure flow field system which becomes novel wind power generation basic theory and system engineering technology. By the flow-collecting control of the flow field, the system changes the wind speed and wind pressure, improves the wind energy density ratio and leads the airflow in nature to be changeable and compressible. When the airflow passes through a vortex body, the pressure of the flow field is changed so that the wind energy conversion ratio of a resistance-typed wind power machine is higher than that of a resistance-increasing wind power machine. A multi-pole differential-speed power generator is suitable for working at a rated power under the minimum and maximum wind speed working condition, thus realizing high-capability assembly of a single unit. The system changes the Betz theory created by Betz who is a famous physical scientist in Germany and is the founder of wind power theory on the basis of natural flow field, and negates the issue that in the Betz theory system, the airflow in the nature can not be compressed and the issue that the wind energy conversion ratio of the resistance-increasing wind power machine is more than that of the resistance-type wind power machine.

Description

Technical field [0001] The patent of this invention relates to the basic theory and system engineering technology of a wind power generation system, especially the basic theory and engineering technology of "integration, control and rectification system", "vertical axis vortex wind turbine system" and "multi-pole differential speed system" , has changed the traditional, low-efficiency, and immature "Bates theory" founded by the famous German physicist Bates based on the natural flow field. The patent of the present invention utilizes the collection and flow control system to change the direction, speed and pressure of the airflow per unit area in nature, so as to increase the wind energy density ratio. When the high-density specific wind energy enters the vortex fluid, a high wind pressure area is formed, and the vortex wind turbine is pushed to make a retreat movement, so that the wind energy utilization ratio of the resistance wind turbine exceeds 0.95. When the vertical axi...
