Embodiment Construction
[0034] figure 1 is a simplified perspective view of a wind turbine 2 . By way of example, the wind generator 2 is an offshore wind generator. It comprises a rotor hub 4 carrying rotor blades 6 . A supporting structure 8 , such as a tower, carries the nacelle (not visible) and rests on a suitable underwater foundation in the sea 10 . Each rotor blade 6 can be rotated by a pitch angle The pitch action is performed by a pitch drive system, usually installed in the rotor hub 4 . The nacelle can be moved by azimuth drive. There are also other drive systems not shown. The invention applies to any drive system having a drive motor and a drive gear or stage.
[0035] exist figure 2 , there is a simplified schematic drawing illustrating a system 12 for early error detection in a drive system, which in this embodiment can be a pitch drive system, but can also be any other drive system of a wind turbine , especially the nacelle drive (azimuth drive, yaw drive) system or the mai...

A system for early error detection in a drive system of a wind generator is provided. The system comprises a first rotation sensor, which is coupled to an input shaft of the drive gear or transmission stage. This first sensor captures an input angle of rotation. Furthermore, the system comprises a second rotation sensor, which is coupled to an output shaft of the drive gear or transmission stage. The output angle, which is acquired by the second sensor, represents an output of the drive gear or transmission stage, which is performed in response to the input angle. The system also includes a control unit, which is configured to simultaneously capture a first and a second time dependent signal, which are indicative of the input angle and the output angle, respectively. The control unit is configured to determine a time dependent angle difference from the first and the second signal under consideration of the transmission ratio of the drive gear or transmission stage. Furthermore, the control unit analyzes this time dependent angle difference so as to perform early error detection in the drive system.
Description
technical field [0001] The invention relates to a system for early error detection in a drive system of a wind power generator. The invention also relates to a wind generator comprising the system and to the use of the system. Furthermore, the invention relates to a method for early error detection in a drive system of a wind power generator. Background technique [0002] One of the fundamental operating components in a wind generator is the pitch drive system for adjusting the pitch of the rotor blades during operation. In space drives, the space bearing represents one of the key components. When a spacing system suffers from errors during use, this can be related to various mechanical failures, such as broken bearings, broken gear teeth, imbalance, misalignment or even broken shafts. Mechanical damage can be caused by corrosion, friction, lack of grease, fatigue, and the like. Failures in the pitch drive system increase the risk of blade pitch blocking, which can be cr...
