摘要： A method for the calculation of a wind turbine blade deflection is described. The method utilises a known blade modal profile in the calculation of the blade deflection, such that the a priori knowledge of the blade excitation modes can be used with a simple distance measurement to determine the blade deflection shape. The calculated blade deflection can then be used as an input to control wind turbine operation, e.g. where it is likely that the deflected blade might result in a tower strike.

摘要： 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.

摘要： The invention relates to a method for the efficiency monitoring of a wind farm. The method according to the invention is characterised by the following steps: measuring at least one wind speed and one wind direction over a specifiable time period, measuring a power of the wind farm in the specifiable time period, associating the power with the measured wind speed and the measured wind direction, storing the power as a power value in a first power matrix, in which matrix elements are associated with various wind speeds and wind direction, providing a first counting matrix having matrix elements that are associated with various wind speeds and wind directions, adding a counting value to the matrix element of the first counting matrix that corresponds to the measured wind speed and the measured wind direction. The aforementioned steps are performed for a plurality of specifiable time periods in a reference duration. The same steps are performed in a later monitoring duration in order to form a second power matrix and a second counting matrix. For the efficiency monitoring, the power values of the first power matrix weighted to the second counting matrix are compared with the second power matrix.
