Wind-power plant i.e. off-shore-system, for power generation, has generator with low power causing rotation speed reduction for another generator with high power, where generators are coupled with each other and commonly driven

摘要

The plant (1) has a rotor (2) provided with adjustable rotor blades (3). A planetary gear (7) follows a gear box (5) of a drive train (4). A power generating unit (8) is coupled with the drive train. The power generating unit including generators (9, 11) with different powers. The generators are coupled with each other and commonly driven. One of the generators (11) with a low power causes rotation speed reduction for the other generator (9) with high power. One of the generators (11) includes a stator, which is arranged opposite to an internal gear (16). An independent claim is also included for a method for power generation by a wind-power plant.
