The WinDrive principle is based on a hydrodynamic converter in combination with a superimposing planetary gear stage.
Because the hydrodynamic speed control component in the WinDrive is a fluid device and has similar power characteristics to the wind rotor, it is ideally suited to be coupled together with the wind turbine rotor. The wind turbine rotor is always operated at its optimum speed for any wind speed.
The WinRotor is coupled to the WinDrive via the main gear box. The input speed to the synchronous generator (i.e. output of the WinDrive) is always at a constant speed.
The drive train concept with WinDrive eliminates the requirement for power electronics for frequency conversion. The synchronous generator also makes it possible to achieve excellent feed qualities to the electrical grid. In addition, this drive concept enables a reduction in weight and the space required in the nacelles of the wind turbine. |
