The protection principle diagram can show the function realization process of the microcomputer protection software module, furthermore, it can be utilized for simulation to repeat protection function details. The paper designs an analysis and calculation method to get the detail procedure in protection action process simulation. Firstly, the paper constructs a schematic diagram model consistent with the actual microcomputer protection equipment. Secondly, the paper proposed the method to calculate the action sequence of each functional graphic element in the relay protection schematic model in real time, and so on, the state change process of each functional graphic element is obtained and recorded. As a result, it is inferenced of the state change sequence of the functional graphic element in the protection schematic diagram. Furthermore, the joint calculation of multiple protection schematic diagrams is achieved through the associated attributes of the graphic elements. The dynamic change process of each link in protection schematic simulation is reproduced by the proposed method for protection training simulation. The engineering practice of the simulation system verifies the effectiveness and real-time performance of the method.
