A high-speed voltage-regulating and static-excitation system for A-C aircraft generators
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1960 WITHIN the past few years there has been developed a new type of voltage-regulating and static-excitation system for a 40-kva (kilovolt-ampere) a-c aircraft generator. The system is unique in its manner of excitation control, and exhibits rather remarkable performance.

Experience with Supplementary Damping Signals for Generator Static Excitation Systems
IEEE Transactions on Power Apparatus and Systems, 1973 Virtually all hydraulic generating units installed in Ontario Hydro since 1964 have been equipped with static excitation systems, necessitating supplementary stabilizing signals to suppress power oscillations. This paper reviews the experience gained with alternative types of stabilizing systems at these stations and discusses advantages and ...

Stabilization of statically unstable systems by parametric excitation
Journal of Sound and Vibration, 2009A linear vibrational system with multiple degrees of freedom subjected to parametric excitation is considered. It is assumed that the system is statically unstable but close to a critical point, the excitation amplitude and damping are small, and the excitation frequency is arbitrary.

Adaptive and robust controls for static excitation systems
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2015Purpose – Oscillations and related stability problems of synchronous generators are harmful and can lead to power outage. Studies have shown that currently available commercial applications of power system stabilizers (PSSs) do not ensure damping of modern generators operating in contemporary power systems at peak performances.

Excitation of oscillations in nonlinear systems under static feedback
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004New conditions for oscillatority of a system in the sense of Yakubovich (1973) are proposed. These conditions are applicable to nonlinear systems decomposed into two nonlinear parts. Upper and lower bounds for oscillation amplitude are obtained. The relation between the oscillatority bounds and excitability indices for the systems with the input are ...

Applying Static Excitation Systems
IEEE Industry Applications Magazine, 1998Many power generation plants in the pulp and paper industry are faced with high maintenance and downtime due to the excitation system. DC field breakers, motor driven rheostats, rotating exciter failures, commutator deterioration, and replacement parts for the automatic voltage regulator (AVR) are just a few of the problems typical of these aged power ...

Retrofitting static exciter regulators for rotating exciter systems
Conference Record of Annual Pulp and Paper Industry Technical Conference, 2003The author reviews the various rotating exciter systems and their retrofitting to new static exciter excitation equipment. It is noted that, where rotary exciter rewinding and general excitation system upgrading is considered, the shunt static exciter regulator represents an attractive alternative to power plant life extension.
