Abstract
Multiple induction type generators are drivingly connected to an impeller. As wind velocity increases, the generators are successively activated until all of the generators are operating at a maximum wind velocity. As the wind velocity decreases, the generators are successively de-activated until all of the generators are inoperative below a minimum wind velocity. Wind energy is more efficiently converted into electric power where impeller RPM must be maintained substantially constant under varying wind conditions to achieve the desired constant phase of the AC output.
Claims13
A wind powered generator comprising:
- an impeller;
- means for supporting the impeller for rotation by the wind;
- a plurality of generators each having an input shaft;
- means providing a continuous driving connection between the impeller and the input shaft of each of the generators for continuous co-rotation thereof;
- and
- control means responsive to wind velocity for successively activating the generators as the wind velocity increases and for successively de-activating the generators as the wind velocity decreases.
A wind powered generator comprising:
- an impeller;
- means for supporting the impeller for rotation by the wind;
- a plurality of generators each having an input shaft;
- transmission means for providing a continuous driving connection between the impeller and the input shaft of each of the generators for continuous co-rotation thereof;
- and
- control means responsive to wind velocity for activating a first one of the generators when the wind velocity exceeds a predetermined minimum, for successively activating additional ones of the generators as the wind speed increases until all of the generators are activated when the wind velocity exceeds a predetermined maximum, for de-activating a first one of the generators when the wind velocity falls below the predetermined maximum, and for successively de-activating additional ones of the generators as the wind velocity decreases until all of the generators are de-activated when the wind velocity is below the predetermined minimum.
A wind powered generator comprising:
- an impeller;
- means for supporting the impeller for rotation by the wind;
- a plurality of generators each having an input shaft;
- transmission means for providing a continuous driving connection between the impeller and the input shaft of each of the generators for continuous co-rotation thereof;
- and
- control means responsive to wind velocity for selectively and simultaneously activating one or more of the generators for maximizing the amount of electric power produced under varying wind velocities while maintaining a substantially constant impeller RPM.
