The invention discloses a rapid transmission method of model data in distributed simulation of power equipment. The method comprises the steps of constructing a network topological graph of each site in a simulation system of the distributed power equipment, obtaining mean data transmission time between the sites, generating a shortest path tree taking a target site as a root node by using a Dijkstra's algorithm, generating a structure tree of a simulation model, analyzing a required submodule in a target included in each site, forming a submodule transmission candidate list, carrying out submodule transmission path planning from small to large from a leaf node according to the transmission time based on the list and the structure tree of the model to achieve rapid distributed transmission of the simulation model of the power equipment. The method greatly improves model transmission efficiency in the distributed simulation system, shortens the transmission time of a model network, and therefore ensures a simulation effect and continuity.
