To improve safe operation of power network, a loop closing analytical calculation system based on electromagnetic-electromechanical transient hybrid simulation theory is developed. An automatic electromagnetic network partition solution based on the maximal stair search algorithm is put forward. The system also implements the function of automatic transformation from the electromechanical transient models to electromagnetic models and links the geographic maps and station maps, which not only makes loop closing operation easy but also enhances veracity. Simulation and calculation results show that the system can increase the accuracy of loop closing, providing evidence for loop closing operation.
