Generator set operation parameter monitoring method and system based on information fusion

The invention discloses a generator set operation parameter monitoring method and system based on information fusion, and the method comprises the steps: collecting historical data of each operation parameter of a generator set, carrying out the preprocessing, and determining a characteristic parameter which affects a monitored target parameter; acquiring operation data information of the target parameters and the characteristic parameters in a sliding time sequence of a set sliding window, and substituting the operation data information into a regression formula of a linear function to perform regression calculation to obtain a corresponding regression coefficient; constructing a coefficient deviation monitoring index of the target parameter in the current sliding window according to the regression coefficient; based on the coefficient deviation monitoring index of the current sliding window, calculating a threshold value of a next sliding window by using an AR autoregression prediction method; and when it i
