Abstract
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.
