A system for electric power production from wind includes a glider having an airfoil, an on-board steering unit, a flight controller for controlling the steering unit, and a connection unit for a tether. The system further includes a ground station including a reel for the tether, a rotating electrical machine connected to the reel, and a ground station controller for controlling the reel and the rotating electrical machine. A master controller operates the system in at least first and second operation modes. In the first operation mode electric power is produced with the rotating electrical machine from rotation of the reel caused by reeling out the tether using a lift force generated upon exposure of the airfoil of the airborne glider to wind. In the second operation mode, the reel is driven by the rotating electrical machine, thereby reeling in the tether onto the reel. |

1. A system for electric power production from wind comprising a glider, said glider having an airfoil, on-board steering unit for pitching, rolling and yawing the glider when airborne, a flight controller for operation of the steering unit, and a connection unit for a tether, the system further comprising a ground station, said ground station comprising a reel for the tether, a rotating electrical machine connected to the reel, and a ground station controller for operation of the reel and the rotating electrical machine, and the system further comprising a master controller for operation of the system in at least two alternative operation modes, wherein a first operation mode of the system is provided for electric power production with the rotating electrical machine from a rotation of the reel induced by reeling out the tether using a lift force generated upon exposure of the airfoil of the airborne glider to wind, and wherein a second operation mode of the system is provided for system recovery by driving the reel with the rotating electrical machine, thereby reeling in the tether onto the reel. |
