Example Embodiment

[0073] Example

[0074] Set the rated output power of each wind turbine (6) to 1500kw (the diameter of its conventional wind wheel is about 60 meters). Assuming that the efficiency of the generator and the speed increasing gear is 0.8, the rated wind speed is 25 m / s (corresponding to the environmental natural wind speed at the air inlet (3) of the air duct is 12.5 m / s), the wind wheel of the wind generator (8 The empirical calculation formula for) is:

[0075] P=0.2*D 2 *V 3

[0076] P is the output power provided by the wind turbine, which is equal to the rated output power of the wind turbine divided by the efficiency of the generator and the speed increasing gear 0.8,

[0077] P=1500kw / 0.8=1875kw,

[0078] V is the rated wind speed, which is designed to be 25 m / s,

[0079] It is obtained that the diameter D of the wind turbine wheel (8) is equal to 24.5 meters, which is only 1 / 3 of the diameter of the conventional 1500kw wind turbine wheel.

[0080] Two wind turbines (6) of the embod...

Abstract

A new energy-gathering wind power generation device that adopts the dynamic control of a split-flow wind regulating device, including two wind collecting walls (1) connected with a steel-structured air outlet frame (4) to form a trumpet-shaped wind collecting air duct (2 ) to form a wind energy gathering device, so that the wind speed at the position of the air duct outlet frame (4) is increased, and several high-power wind turbines (6) with miniaturized typhoon wheels are installed on the air duct outlet frame (4). Multi-layer round hole type split flow automatic wind regulator (7) is installed on the wind wall (1), each round hole type split flow automatic wind regulator (7) is connected by a round hole (9) and N folding Sector blade (10) and driving motor (12) constitute. The dynamic control of the automatic wind regulator (7) and the operation of the fixed-pitch two-speed asynchronous generator form a unified cooperative control system. Control and stabilize the operating wind speed of wind turbines, improve the efficiency of wind turbines, increase power generation, and use wind energy more effectively.

Description

Technical field [0001] The present invention relates to a novel energy-concentrating wind power generation device adopting a split-type wind regulating device, in particular to a novel energy-concentrating wind power generation device adopting a split-type wind regulating device that can better utilize wind energy and improve the power generation capacity of the wind generator. Background technique [0002] Limitations of traditional wind power plants: [0003] Although wind power has developed tremendously, it cannot be compared with conventional power generation technologies (water, fire, and even nuclear power) in terms of industrial application scale. There are reasons for the characteristics of wind energy resources, such as low energy density, space, The uneven time distribution and the large changes in wind direction and speed are also related to the basic technology of wind power generation, that is, the design of wind power generation devices has not made a breakthrough. ...
