| description | The invention provides a cylinder valve out-of-step fault monitoring method and device, and is applied to the technical field of water turbine fault detection. The method comprises the steps that in the barrel valve opening and closing process, the displacement value of each barrel valve servomotor at the current moment is obtained; according to the displacement values, displacement deviation absolute values between each cylinder valve servomotor and other cylinder valve servomotors in the multiple cylinder valve servomotors are determined; and according to the displacement deviation absolute value, whether the cylinder valve has an out-of-step fault at the current moment is determined. According to the scheme, the out-of-step fault of the cylinder valve can be monitored in real time in the opening and closing process of the cylinder valve, so that the abnormal operation of the cylinder valve can be monitored in time, corresponding workers can handle the abnormal operation in time, the maintenance cost of the |
