Load model: Induction motors in large disturbance

The aim of this work is to propose a simple methodology that facilitates characterization of the power system load, particularly induction motors, taking into account the different possible responses of induction motors to large disturbance. Since the nonlinearities associated with induction motors imply different responses if an induction motor reaccelerates, trips or stalls in the post-disturbance period, the induction motor load model can be improved identifying the percentages of reaccelerated, stalled and tripped induction motors. The aim is to build these models from system measurements.
