Energy generation installation with an adjustable-speed gear

摘要

A variable-speed transmission for a power-generating plant; with an input shaft which is connected at least indirectly with a power transducer of a wind-energy generator or hydroelectric generator; with an output shaft which is connected at least indirectly with an electric generator, with the speed of the output shaft being substantially constant; with a superposition gear which is connected at least indirectly with the input shaft and which divides power among a first power branch connected at least indirectly with the output shaft and a second power branch; with the second power branch comprising at least two hydrodynamic circulations, with at least one of the hydrodynamic circulations being at least indirectly in connection with the first power branch.
