Hydropower plant intelligent vibration reduction method based on magnetorheological damper
The invention discloses an intelligent damping method for a hydropower station workshop based on a magnetorheological damper. The intelligent damping method comprises the following steps that (1) a vibration sensor collects the vibration response of a workshop structure in the operation process of a generator set; (2) constructing a hydropower station workshop vibration response prediction model, and predicting a vibration response value of a hydropower station workshop vibration reduction part in real time by using the trained hydropower station workshop vibration response prediction model; (3) the magneto-rheological damping device outputs damping force in real time to reduce the vibration response of the factory building; (4) when a workshop vibration response prediction result of the hydropower station workshop vibration response prediction model reaches a preset threshold value, the fuzzy logic controller receives vibration response prediction data and controls the magneto-rheological damping device; and (5) the magneto-rheological damping device outputs magneto-rheological damping force through the magnitude of current transmitted by the fuzzy logic controller, and the magneto-rheological damping force acts on the corresponding part of the hydropower station workshop structure. According to the method, intelligentization of factory building vibration response control can be realized.
