An electromagnetic transient simulation method and an electromagnetic transient simulation device provided by the invention relate to the technical field of electromagnetic transient simulation. The method comprises the following steps: taking any one of a plurality of subsystems as a target subsystem, obtaining Thevenin equivalent impedance matrix and Thevenin equivalent voltage source of the target subsystem at the boundary of the current time, and obtaining Thevenin equivalent voltage source of the boundary of the other subsystems at the current time; calculating the tie line current vectorat the current time according to the obtained Thevenin equivalent impedance matrix and the Thevenin equivalent voltage source; calculating the node voltage vector of each subsystem at the current time according to the tie line current vector, and calculating the internal electric quantity of the target subsystem according to the node voltage vector of each subsystem. Through the above method, theproblem of large computat
