Simulation of synchronous machines in phase coordinates including magneticsaturation

This paper describes a novel way to account for magnetic saturation for sim ulation of synchronous machines in phase coordinate for power system studie s. A synchronous machine model in phase coordinates is presented and the ef fect of saturation along direct and quadrature axes are taken into account by identifying the flux linkages of individual phases in terms of the flux linkages of direct and quadrature axes. The proposed model was simulated us ing the high-level dynamic simulation language (DSL) and its performance wa s compared with the standard dqo model in SIMPOW(TM) for a sample round rot or machine.
