Parameters of induction motors have crucial effects on power system simulation. This paper proposes a dynamic aggregation method motors. In this method, firstly, starting off the electromechanical models motors, taking coefficients equations and steady state slips as characteristic vectors, are grouped with fuzzy C-means clustering method. Then, equivalent motor obtained by averaging that individual in same group. Finally, parameters calculated based relationship transient impedance before after aggregation, principle active reactive loads equal aggregation. Simulation results show proposed can improve precision simulation
