摘要： The present invention relates to a method for monitoring blade frequencies of a wind turbine and a monitoring system for performing the method. By the invention an accelerometer or G-sensor is placed into the nacelle of a wind turbine and thereby measuring the vibrations of the nacelle. To extract the vibration signals originating from each blade, the vibration signals are combined with the measuring signals from the azimuth angle sensor (rotating angle), which is normally used for pitch control. To further extract each blade frequency a Fast Fourier Transformation (FFT) is used on the modulated G-sensor signals. To further monitor a severe and alarming change in each blade frequency each blade frequency is compared to the other blade frequencies and an alarm is set if a given level is reached.

摘要： The invention relates to a method and a device for operating a wind farm comprising a plurality of wind turbines. According to said method, operating parameters of the wind turbines of the wind farm are adjusted according to an optimization goal, said optimization goal being the maximum value of the total output of the wind farm produced from the sum of all individual outputs of the wind turbines. The optimization goal differs from conventional optimization goals where the respective individual outputs of the wind turbines are optimized without taking the overall output into consideration. The inventors were able to demonstrate that the optimization goal according to the invention allows an improvement of the overall output.
