摘要： A method for monitoring blade frequencies of a wind turbine and a monitoring system are provided. An accelerometer is attached to a rotating hub of a wind turbine measuring vibrations of the hub. To extract vibration signals originating from each blade, the vibration signals are combined with measuring signals from the azimuth angle sensor. Alternatively, the azimuth angle is found by using the measured accelerations in two directions representing the centrifugal forces and vibrating forces of the hub and feeding these signals into a phase locked loop unit establishing a phase of the rotating hub representing the azimuth angle. To extract each blade frequency, a Fast Fourier Transformation is used on the signals from the accelerometer. To monitor a severe change in each blade frequency, each blade frequency is compared to other blade frequencies and an alarm is set when a given level is reached and the wind turbine is stopped.

摘要： A method for controlling dynamic power factor or the reactive power of a wind farm is provided. The wind farm comprises a number of wind turbines connected to a utility grid driven with a requested power factor or a requested reactive power. The wind turbine output voltage is controlled to a specific voltage set point. In the method, the wind farm power factor is measured and compared with the power factor requested for the utility grid, or the wind farm reactive power is measured and compared with the reactive power requested for the utility grid, respectively; the ratio of the wind farm voltage to the utility grid voltage is adjusted, and the output voltage of the individual wind turbines is regulated to correspond to the specific voltage set point; the steps are repeated until the power factor of the wind farm electricity corresponds to the requested reactive power.

摘要： One or more bolt gauges each with a built-in load cell are positioned on a blade bolt or a bearing bolt between a pitch bearing and a tightening means and tensioned by the securing means at the inside or the outside of a hub of a wind turbine. The bolt gauge then outputs a signal descending both from the tension from the bolt/securing means connection and the tension from the blade when the blade is vibrated due to wind forces and the rotation of the blade when the hub of the wind turbine is rotating.
