    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.
