Substation secondary circuit multi-simulation tool co-simulation method and system

The invention discloses a substation secondary circuit multi-simulation tool co-simulation method and system, and relates to the technical field of secondary circuit simulation modeling, and the method specifically comprises the following steps: reading a to-be-simulated secondary circuit, and determining the attribute information of each element; establishing an element mathematical model according to the attribute information of each element; calling corresponding elements from the element mathematical model, performing logical configuration according to the secondary circuit to be simulated, and constructing a virtual secondary circuit; if no corresponding element exists in the element mathematical model, creating a new user-defined control and adding the new user-defined control into the element mathematical model; and establishing a control program on the Labview simulation platform and downloading the virtual secondary circuit to the board card to complete the mapping of the secondary circuit to be simu
