The saturated synchronous machine
Electrical Engineering, 1937Discussion of a paper by B. L. Robertson/ T. A. Rogers, and C. F. Dalziel published in the July 1937 issue, pages 858–63, and presented for oral discussion at the electrical machinery session of the Pacific Coast convention, Spokane, Wash., September 2, 1937.

Synchronizing transients and synchronizers for large machines
Electrical Engineering, 1940IT IS a curious fact that the phenomena encountered in synchronizing operations have received scant attention in the technical literature even though the phenomena have been encountered ever since two synchronous machines were first operated in parallel, and even though a large number of synchronizing operations are performed every day.

Contributions to Synchronous-Machine Theory
Transactions of the American Institute of Electrical Engineers, 1937Discussion and author's closure of a paper by A. S. Langsdorf published in the January 1937 issue, pages 41–48, and presented for oral discussion at the synchronous machinery session of the winter convention, New York, N. Y., January 27, 1937.

Synchronous machine oscillations
1980We have seen that the dynamical stability of an electromechanical system is determined by the damping and synchronising torque coefficients and the inertia constants. In a mechanical system damping and spring constants can be easily visualised—damping, for instance arises due to friction. In an electrical system, mechanical friction constitutes a small

In this chapter, we analyze state-based formalisms that extend the basic automata models of Chap. 6 with a notion of time. The discussion progresses from the simplest formalisms to richer and richer extensions that can express sophisticated timing properties. First, we introduce the notion of transition system, which is used to provide the semantics of

Synchronous Machines Equations
1992In this chapter some classes of pendulum-like systems describing the dynamics of synchronous machines are considered. For such systems there are given sufficient conditions for global convergence (synchronous behavior) or for the existence of cycles of the second kind (asynchronous behavior) which are mainly based on the non-local reduction principle ...

Machines synchrones - Excitation
Conversion de l'énergie électrique, 1997Les machines electriques synchrones qui convertissent l’energie mecanique en energie electrique (alternateurs) ou vice versa (moteurs synchrones) necessitent une alimentation en courant continu de leur inducteur ou systeme d’excitation . En outre, l’existence de ce dispositif permet, suivant les cas, de regler la tension ou la puissance reactive ...
