The invention discloses a voltage regulating moment-based main transformer high-voltage side bus voltage overrun processing method. Firstly, the invention defines the concept of regulating moment, andsynthetically analyzes the regulating moment, regulating time and regulating cost of each regulating node to form the regulating function of each regulating node corresponding to the high-voltage side bus overrun node of the main transformer. By sorting the regulating function values of each regulating node and screening from many regulating strategies, the candidate set of regulating strategy suitable for high voltage side voltage overrun of main transformer is obtained. Finally, according to the candidate strategy, the voltage of the node overrun is regulated by reactive power optimizationmodel. The invention reduces the range of the selection of the adjustment variable and simplifies the adjustment procedure by utilizing the adjustment strategy candidate set. The method of the invention has the advantages of f
