Abstract: Categorizes three direct-axis and four quadrature-axis models, along with the basic transient( g d2 @4 r6 s
reactance model. Discusses some of the assumptions made in using various models and presents the " @% q# S- V( X, \$ q, a2 ]! Yfundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various) L8 j) [: _9 Q- C, r$ g5 l. Q! m' w
