The invention discloses a current transformer modeling method and apparatus, a storage medium and a processor. The method comprises the steps of obtaining a target parameter of a current transformer, wherein the current transformer runs in a power system; based on a preset model, building a dynamic analysis model of the current transformer according to the target parameter; packaging the dynamic analysis model into a general module in a preset environment, and performing joint simulation, wherein the general module is connected with modules except the general module in the preset environment; and performing simulation on the current transformer through the general module. Through the method and the apparatus, the effect of improving the accuracy of current transformer modeling is achieved.
