The invention relates to a transformer substation network security intelligent monitoring method and system. The method comprises the steps: reading the network equipment state information of a transformer substation SCADA system, carrying out the feature extraction, obtaining a corresponding equipment state information feature variable, carrying out the normalization processing, and obtaining aninformation feature variable with a unified numerical standard; inputting the characteristic variable training set into a recurrent neural network for training to obtain a network security intelligentmonitoring model; inputting the characteristic variable test set into a network security intelligent monitoring model to obtain an equipment security state characteristic classification result; and performing feature aggregation classification on the equipment safety state feature classification result to obtain an equipment safety state monitoring result. According to the invention, intelligentdecision and processing of
