Abstract

A digital model for transient analysis of salient pole synchronous machines operating in the magnetically saturated regions is developed. Machine parameters used in this model are derived in terms of design particulars, with provisions for magnetic saturation using the magnetization characteristics of stator and rotor cores. Machine inductances are treated as additional clamped variables, continuously being updated during transient performance calculations. The model developed can be particularly useful in predicting transient characteristics of machines during early design stages, which facilitates implementation of necessary design modifications. Although certain transient tests are not feasible on the shop floor, this model can predict such test results. Results of this study include comparisons between model results, laboratory tests, short circuit data obtained by classical methods.
