Abstract: Categorizes three direct-axis and four quadrature-axis models, along with the basic transient# n: [ q/ Q7 N# R! _
reactance model. Discusses some of the assumptions made in using various models and presents the# a, U+ p' f! @8 Q1 o! B4 @
fundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various x' D9 H% _/ x9 k; l# {! u5 I
