An energy generating installation, especially a wind power station, includes a drive shaft connected to a rotor (1), a generator (8) and a differential transmission (11 to 13) provided with three drives or outputs. A first drive is connected to the drive shaft, an output is connected to a generator (8), and a second drive is connected to an electrical differential drive (6, 14). The differential drive (6, 14) is connected to a network (10) via a frequency converter (7, 15) that can be regulated for the active filtering of harmonics of the energy generating installation, especially of the generator (8). |
