TLDR
In this article, mathematical models of varying complexity for the digital computation of transient behaviour of generators and motors in a synchronous power system, and their application in the light of extensive studies which have been made on a model power system.Abstract:
This paper describes mathematical models of varying complexity for the digital computation of transient behaviour of generators and motors in a synchronous power system, and their application in the light of extensive studies which have been made on a model power system. The computed and measured responses to transient disturbances are compared and the representation of terms in the equations which substantially affect behaviour is discussed.read more

The Theory of Neglecting Stator Transients
TL;DR: In this paper, the equivalence of neglecting the pq terms in the synchronous reference frame is to neglect the p* and Aw terms in all other reference frames in R-L transmission systems, synchronous and induction machines.

A weighted-least-squares parameter estimator for synchronous machines
TL;DR: In this article, an iterative algorithm based on weighted-least-squares estimation theory is proposed to determine directly all standard parameters for a hypothesized model structure by repeatedly processing the armature and field current data of a sudden short-circuit test.

Two-reaction theory of synchronous machines — Part II
TL;DR: In this article, the analysis presented in a previous paper is extended to include a consideration of synchronizing and damping torque during continuous and transient oscillations, the description of an equivalent circuit which has been found useful in calculating the decrement of the short circuit current of interconnected machines, and the derivation of simple approximate formulas for the roots of the equation determining the wave shape of the current on three-phase short circuit.

An Analysis of the Induction Machine
TL;DR: The stationary-axis method was used in this article to evaluate the performance of induction motors under transient conditions, such as when driving pulsating compressor loads, and it has been successfully applied to the analysis of salient-pole synchronous machines.

General-purpose turbo-alternator model
TL;DR: In this article, the authors describe the development of a mathematical model which includes many of the features normally neglected in conventional network-analyser and digital-computer studies, such as mechanical and electrical damping, flux variations, iron saturation and saliency, and also permits the inclusion of voltage-regulator and governor action.

An Analysis of the Induction Motor
TL;DR: For problems involving induction motors other than the usual balanced winding type operating under steady-state conditions, a general method of analysis is necessary as mentioned in this paper, and in particular, its use in short-circuit problems is described.
