cient and Accurate Model for the Simulation Synchronous Machindconverter Systems

Abstract A new synchronous machine model is presented which is readily implemented in either circuit-based or differentialequation-based simulation programs. This model is well suited for the simulation and analysis of synchronous machine converter systems. It is based upon standard representations and no approhations are made in its derivation. However, the numerical implementation is shown to be significantly more eEcient An example is provided which demonstrates a 1700% increase in si" lation speed with no observable lws in accuracy. The model includes provisions for an arbitrary number of damper or rotor windings and may be easily modified to represent synchronous or induction machines with an arbitrary number of stator phases.
