| description | The invention discloses an active early warning method and device for abnormal temperature of a transformer. The method comprises the steps that the temperature of each temperature measurement point outside the transformer at each temperature measurement moment and the environment state parameters of the transformer in the temperature measurement process are acquired; according to the temperature of each temperature measurement point at each temperature measurement moment, obtaining the position and the temperature of the internal hot spot of the transformer at each temperature measurement moment by using a transformer internal hot spot temperature inversion model to serve as inversion temperature field space-time distribution data, and according to the environment state parameters, obtaining the inversion temperature field space-time distribution data by using a power transformer multi-scale reduced-order model to obtain the inversion temperature field space-time distribution data.
