“…The value of Xq required to match test data is considerably lower than the standard unsaturated value obtained from manufacturers. This seems to confirm findings of several other investigators [6,7,8] and also those of the authors in deriving Xq from stator decrement tests [1,2].…”

Prediction of synchronous machine steady state and transient performance requires proper account of iron saturation effects. This paper explores, with simplifying assumptions, the physics of saliency and saturation and evaluates the capability of two alternate methods of saturation representation through comparisons of the calculations versus published test data for the Lambton generator of Ontario Hydro.Presented also are results of sensitivity to variations in parameters atnd model structures.

“…However, there are not many studies based on meas-ured data, since the measurement process is quite a difficult task to carry out. In this study, we proposed a new viewpoint by using x q g which obtained from performance tests of 2-pole 500,000-kVA class generator [5]. The reactance values and time constants obtained by the load rejection test are given in the appendix.…”

Two‐pole large generators are extensively used in power utilities. Growing demand for electric power in recent years has led to substantial increases in the capacity of generators. In line with this trend, our company has manufactured two‐pole turbine generators in the 900,000‐kVA to 1,200,000‐kVA classes. As the capacity of generators becomes larger, equivalent circuits are increasingly expected to improve their precision in estimating operation characteristics. The Park model has been widely used as an equivalent circuit model. The Park model with quadrature axis transient reactance \documentclass{article}\usepackage{amsmath}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{amsfonts}\pagestyle{empty}\begin{document}$x_{q}^{\prime}$\end{document} is claimed to be useful for accurately estimating the load rejection characteristics of turbine generators. However, it is difficult to measure \documentclass{article}\usepackage{amsmath}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{amsfonts}\pagestyle{empty}\begin{document}$x_{q}^{\prime}$\end{document}, few studies based on measured data have appeared. As one of the few examples, we have conducted a measured data on a 500,000‐kVA‐class generator. Recently, the authors obtained test data on \documentclass{article}\usepackage{amsmath}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{amsfonts}\pagestyle{empty}\begin{document}$x_{q}^{\prime}$\end{document} of a 900,000‐kVA‐class generator. In this study, based on these data, we studied the effect of \documentclass{article}\usepackage{amsmath}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{amsfonts}\pagestyle{empty}\begin{document}$x_{q}^{\prime}$\end{document} using the finite element method and a transient analysis program (EMTP‐ATP). © 2011 Wiley Periodicals, Inc.
