Dynamic models of 3-phase alternators including saliency effects using Pspice for windows

This paper presents the dynamic model of a 3phase synchronous machine using the graphical user interface provided by the PSpice program environment. 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, torque, and power traces. The model is organized in a hierarchical structure and includes custom symbols for the machine several functional modules like reference frame transformation modules. The custom symbols have been created within the Schematics editor of the PSpice program group. Details of the implementation as well as the theoretical equations are presented. The model that is shown in this paper is working on the free evaluation version of the PSpice software, Release 6.2a.
