Abstract Power system Low frequency oscillation has become a key factor that endanger the safe operation of the system, and the model and parameter influence on the system dynamic behavior can be completely reflected by the disturbed trajectory. The empirical mode decomposition (EMD) is briefly introduced in this paper, and a new method for eliminating non-stationary trend of Perturbed Trajectory based on empirical mode decomposition is proposed. The simulation result proves the validity and superiority.
