A method for utilizing wind energy for electricity production based on a wind motor and an auxiliary direct current electric motor coupled by an angular speed summation mechanism to an alternating current electric generator maintained at constant speed. The generator can be connected to a power grid or can supply local user appliances by means of a circuit to which other constant frequency generators are either connected or not. If connected to the power grid or to other generators, electricity can be produced at constant frequency by the wind with high efficiency by modulating the power supplied by the auxiliary electric motor. In the case of isolated operation, a low priority user appliance which can be modulated over a certain range has also to be provided in order to produce wind electricity under optimum conditions.
A method for utilizing wind energy for constant frequency electricity production, characterised in that a wind rotor is coupled by means of an angular speed summation mechanism to an auxiliary direct current electric motor and to a generator which is maintained at constant angular speed, the angular speed of said generator being greater than or equal to the angular speed of such wind rotor said summation mechanism comprising a differential having a pinion spider connected to said generator and two axles, the first of said two axles connected to said auxiliary electric motor and the second of said two axles connected to said wind rotor.
