Abstract
The invention relates to a turbine and to the implementation method thereof, said turbine comprising a blade mounted such that it can rotate about a central axis and an electromagnetic synchronous machine arranged with the blade in such a way as to modify the angular rotation speed of the blade in order to optimize the mechanical efficiency of the blade as a function of the speed of the incident fluid acting on the blade.

A turbine comprising
- a plurality of blades mounted to rotate about a central axis,
- a synchronous electromagnetic machine, and
- adjustment means for regulation of a rotational angular velocity of the blades by the synchronous electromagnetic machine to optimize a mechanical efficiency of said blades according to a speed of fluid impinging upon said blades so that the mechanical efficiency of the turbine is optimized for all speeds or variations in speed of the incident fluid,
- the synchronous machine comprising:
- a rotor and
- a stator,
- the rotor comprising a regulator magnet mounted on one or more of the blades, the stator comprising at least one regulator coil,
- wherein during regulation, regulator current is supplied to the at least one regulator coil to regulate the rotational angular velocity of the blades, and
- wherein the adjustment means comprises means of measuring the rotational angular velocity of the blades and the speed of the associated incident fluid, said measurement means being connected to a processing unit for calculating the optimum rotational angular velocity of the blades for which velocity the mechanical efficiency of the blades is at a maximum and for which the mechanical power transmitted to a shaft of the turbine is optimized, using operating charts stored in a memory unit, and the processing unit being connected to the synchronous machine so as to adjust, by accelerating or slowing, the rotational angular velocity of the blades to the optimum rotational angular velocity based upon the calculated optimum rotational angular velocity.
