  • Patent number: 11181130
    Abstract: An abnormality diagnosis method is targeted at a hydraulic device which includes a hydraulic pump and a driven device driven by the hydraulic pump. The method includes calculating a frequency distribution with regard to a deviation between a normal value of an output parameter corresponding to an operation condition and an actual measurement value of the output parameter using a prediction model, and determining the presence of an abnormality if an average of the deviation exceeds a threshold. If the presence of the abnormality is determined, a factor of the abnormality is estimated based on the range of the deviation where a waveform peak of the frequency distribution exists.

  • Publication number: 20130323051
    Abstract: An object is to facilitate checking of functional normality of a pilot check valve. A wind turbine generator includes a pilot check valve for restricting a flow of hydraulic oil relative to each oil hydraulic cylinder for changing a pitch angle of each blade, and the pilot check valve functions for fixing the pitch angle of the blade to a feather position in a state in which rotation of the blade is stopped. The function of the pilot check valve may be hindered. The wind turbine generator detects an operation state of the blade during a process of changing the pitch angle of the blade from the feather position to a fine position, and compares the detected operation state of the blade to an operation state of the blade when the pilot check valve functions normally, to determine whether or not there is any abnormality in the pilot check valve.
