Theoretical and Experimental Analysis of the Squirrel Cage Induction Generators Operating under Unbalanced Conditions

Abstract

This work involves a new approach for the analysis of the squirrel cage induction generators operation operating under unbalanced load conditions. For this purpose, a state model is synthetized considering the change of the stator common point voltage during unbalanced conditions. Theoretical and experimental studies have been investigated to extract some important electromagnetic signatures such as common point voltage, stator voltages and currents. This approach offers a good compromise between modeling precision and simulation time. Simulation and experimental results show good coherence with previous results which have been obtained using symmetrical components and finite elements methods.
