Abstract: Categorizes three direct-axis and four quadrature-axis models, along with the basic transient 2 Y' h* m) m& X% O& ~0 Dreactance model. Discusses some of the assumptions made in using various models and presents the " a4 E7 ^* {; w# [% x" ~fundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various % j1 \, d) }* D; o- M- hattributes of power system stability, recognizing two basic approaches. The first is categorized under large# h3 _) z, g. f0 I/ A, ~+ H
