The invention relates to the field of power system simulation training, in particular to an information modeling method of a power grid control simulation training system. The method includes the following steps that 1, a station end information model is built according to devices; a field Info-upload is added, and control center information of all levels is identified and uploaded; 3, a field Info-duty is added, responsibility zones of the control center information are identified and uploaded; 4, a field Info-Merge is added, the combination attributes of the control center system information are identified and uploaded; 5, according to the name of a monitoring interval, a merge information model is automatically formed through instantiation; 6, the display logic, in control centers of a station end and the responsibility zones of all levels, of information flow of the modeling method is adopted. The modeling method achieves the combination of station end information, control center information and control center merge information, the workload of maintenance is reduced, and the situation that the station end is inconsistent with control information and thus many problems occur is avoided.
