摘要： An object of the present invention is to provide an abnormal vibration detection unit which is capable of stopping a wind turbine generator in a case of detecting excessive vibration that poses danger and is designed suitably for the failure detection. The abnormal vibration detection unit comprises first and second acceleration detectors, a calculation device which receives a first analog output signal that is outputted from the first acceleration detector, a filtering relay which receives a second analog output signal that is outputted from the second acceleration detector, and a safety system which performs an emergency stop of the wind turbine generator in accordance with a state of an output terminal of the filtering relay. The filtering relay comprises a filter circuit part that performs filtering process to extract a predetermined frequency component from the second analog output signal. The calculation device generates a predicted value of the output signal of the filter circuit part by performing digital calculation of the first analog output signals, and detects a failure of the first acceleration detector, the second acceleration detector, or the filter circuit part by comparing the predicted value of the output signal of the filter circuit part with a measured value of the output signal of the filter circuit part received from the filtering relay.

摘要： In a conventional technique, a shutdown sequence indicating a sequential operation from a start of the feathering of a wind turbine to the stop is started in response to an alert signal caused by an external factor. In the present invention, when the alert is called off during the shutdown sequence, the shutdown sequence is stopped, and the recovery control by which the pitch angle of the wind turbine blade is controlled toward the fine state is performed. By such a control, the stop period of the wind turbine under the shutdown can be shortened, so that the decrease in the operating rate of the wind farm can be suppressed.

When shutdown is performed, the individual pitch angle gain is adjusted such that an individual pitch angle gain is reduced gradually and reaches to zero by the individual pitch angle gain producing unit 14 after first set time.
