<p>The invention relates to a method and device for the conversion of a fluid stream of fluctuating speed, such as wind, into electrical current with a constant frequency and voltage. The fluid stream is converted with a turbine into rotation of fluctuation rotation speed, wherein the rotating turbine drives a generator. The generator is provided with setting means for setting the power to be delivered, the settings being dependent on the rotation speed of the turbine.</p> |
