The invention provides a stable emergency control method based on a call wire double-peak track. The stable emergency control method includes the steps of (1) building an interconnected network safety and stability calculation model, (2) evaluating power grid stability after fault disturbance, (3) identifying faults which enable an interconnected power grid to lose stability of synchronization and a corresponding vibration center call wire, (4) determining the corresponding relation among the active power of the vibration center call wire, the stability margin of the interconnected power grid, the busbar voltage at the two ends of the call wire and the busbar phase difference of the two ends of the call wire, (5) formulating the interconnected power grid stability control criteria and strategies, and (6) conducting simulation verification on the effect of the method. According to the stable emergency control method, the track characteristics of the active power of the call wire, where a vibration center is, after large-disturbance motion fault impacts are adopted, the relation between the active power and the system stability is adopted, the characteristics of the station voltage changes at the two ends of the call wire and the characteristics of phase difference changes are integrated, the power grid stability control criteria and strategies are created, the power grid stepout risks are reduced, and the stable operation level of the large-area-crossing interconnected power grid is improved.
