摘要： An assembly for retrofitting fixed speed, doubly fed and fully converted wind turbines. A differential having an output shaft coupled to the main generator and a control shaft to change a ratio between differential input and output and coupled to the auxiliary generator. The main generator operates at constant frequency and is coupled to an electric power grid without a power converter. A variable speed auxiliary generator may be coupled to the electric grid through auxiliary power electronics. A controller may during low loads assign a full load to the auxiliary generator, during typical loads assign a variable shared load between the auxiliary and main generators based on an optimization algorithm and during high loads assign a fixed shared load between the auxiliary and main generators based on the internal gear ratio of the differential. For step-down differentials, at high loads the full load may go to the main generator.
