Abstract
A wind-to-electric power conversion system is disclosed having ratio-variable entrance and exit openings. The ratio is set by sensing the velocity of the incoming wind, thereby effecting the velocity of the blade set driving an A.C. generator through a flywheel and thereby stabilizing the generator speed.
Claims2
A wind to electric system comprising:
- a. a wind collecting structure having an entrance and exit opening;
- b. means for varying the areas of said entrance and exit openings relative to one another;
- c. means for sensing the velocity of an incoming wind;
- d. means coupled to said sensing means for adjusting the ratio between the areas of the entrance and exit openings in accordance with the sensed velocity;
- e. a wind-driven blade set disposed at the exit opening to receive the wind therefrom;
- f. flywheel coupled to the wind-driven blade set;
- g. clutch for decoupling said flywheel and blade set;
- h. an A.C. generator coupled to said flywheel.
