DYNAMIC-MODELS OF 3-PHASE ALTERNATORS INCLUDING SALIENCY EFFECTS USING PSPICE FOR WINDOWS

This paper presents the dynamic model of a 3-phase synchronous machine using the graphical user interface provided by the PSpice program env ironment. The machine model includes the effects of the damper winding and salient poles. The paper presents results of the dynamic behavior of a salient pole synchronous machine including voltage, current, tor que, and power traces. The model is organized in a hierarchical struct ure and includes custom symbols for the machine several functional mod ules like reference frame transformation modules. The custom symbols h ave been created within the Schematics editor of the PSpice program gr oup. Details of the implementation as well as the theoretical equation s are presented. The model that is shown in this paper is working on t he free evaluation version of the PSpice software, Release 6.2a.
