Simulation and back-to-back testing of synchronous machine

Abstract

The dynamic properties of back-to-back single supply high power salient poles synchronous machine are analyzed by modeling and simulation. The considered mathematical model is convenient for high power salient poles synchronous machines. The dynamic electromagnetic torques and windings currents where particularly considered. Of a special concern is also the steady state operation. This issue is of theoretical and practical interest in the field of electrical machines, especially high power, and there are no detailed references in literature. Simulations and experiments confirm the possibility of synchronous operation. The recoverable character of operation is fundamental. The proposed test method at rated load is experimentally validated. It is quite appropriate for high power machines, comparing with other methods.
