Describing the small signal performance of a multi- machine synchronous power system by a set of differential equations of the form [x] = [A] [x] allows standard multivariable control theory to be used in dynamic stability studies. The construction of the [A] matrix for a multimachine power system involves the application of Kron's rotational transformation to the transmission network admittance matrix, and a matrix analysis of the synchronous machines using internal flux linkages as state variables.read more

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.

Analysis of synchronous machines connected to power-system networks
TL;DR: The derivation is given of a matrix procedure for determining the voltages, currents and powers of machines in an efficient manner, this being particularly important in view of the number of times the electrical powers of Machines are computed in the course of a transient-stability calculation.
