Abstract

The invention discloses a method for automatically generating a visual simulation model of an electromagnetic transient state of a power system. The nodes are merged into one power station node, and the topological connection information of the transmission line is retained; the hierarchical layout method of power grids with different voltage levels is used to complete the network topology diagram of each power station, and the modeling range is selected; the electromagnetic transient modeling software is analyzed The simulation model file and modeling method form the topology of the electromagnetic transient simulation model based on the frame selection modeling range; finally form the electromagnetic transient model consistent with the electromechanical transient state. It can display the actual relative position of each plant and station, automatically connect the network topology, and is the same as the power equipment controller in the electromechanical transient data, and can simplify the scale of the power grid model.
