Electric ship power system loads, such as high power weapons and laser guns require flexible controlled power with high power quality. A multiphase synchronous generator provides high quality power with fewer ripples and a smoother current on the DC side. Improving the modeling and simulation of synchronous generators has been a subject of investigation for several decades. Modeling is traditionally based on the dq reference frame to obtain constant coefficients and to simplify the calculations. In this paper, a multiphase synchronous generator has been modeled. Better modeling of a multiphase machine is needed for shipboard power system analysis. The digital model is developed on the simulation platform of PSCAD/EMTDC, using the implicit integration method as the solver for a set of algebraic-differential-integral equations describing the performance of devices. The validity and accuracy of the modeling algorithm are verified by comparing steady state and transient performance of user-defined model with the standard model.
