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. |
