Abstract
A power generation system is disclosed. The power generation system comprises a kite connected to a line. The line is alternatively let out during a traction phase and recovered during a recovery phase. A power extractor connected to the line to extract power during the traction phase. And, a power extraction controller configured to target a preferred traction phase line velocity and a preferred recovery phase line velocity.
Claims36
A power generation system comprising:
- a kite connected to a line wherein the line is alternatively let out during a traction phase and recovered during a recovery phase;
- a power extractor connected to the line to extract power during the traction phase;
- a power extraction controller configured to target a preferred traction phase line velocity and a preferred recovery phase line velocity.
A method for power generation comprising:
- determining a preferred traction phase line velocity and a preferred recovery phase line velocity;
- configuring a controller to target the preferred traction phase line velocity for a line connected to a kite during a traction phase, wherein during the traction phase the line is let out and power is extracted as the line is being let out;
- and
- configuring a controller to target the preferred recovery phase line velocity a line connected to the kite during a recovery phase, wherein during the recovery phase the line is recovered.
A computer program product for power generation, the computer program product being embodied in a computer readable medium and comprising computer instructions for:
- determining a preferred traction phase line velocity and a preferred recovery phase line velocity;
- configuring a controller to target the preferred traction phase line velocity for a line connected to a kite during a traction phase, wherein during the traction phase the line is let out and power is extracted as the line is being let out;
- and
- configuring a controller to target the preferred recovery phase line velocity a line connected to the kite during a recovery phase, wherein during the recovery phase the line is recovered.
