A voltage input-based magnetic equivalent circuit model for wound rotor synchronous machines

A mesh-based dynamic magnetic equivalent circuit model for wound rotor synchronous machines has been derived in this research. As part of this effort, a reluctance network has been enhanced to model flux distribution around stator tooth tips and damper bar openings. Faraday's law is applied to establish a state model in which stator winding flux linkages are selected as state variables. The resulting coupled MEC/state model is solved to analyze machine dynamics.
