Control of Rotating Exciters for Power System Damping: Pilot Applications and Experience

Control of rotating exciters to improve system damping has been carried forward in pilot applications to evaluate practicality, effectiveness, alinement needs, and operating characteristics. The first application to this type of exciter system has been in operation since July 1967. These pilot applications include exciters with rotating amplifier regulators and with static regulators. Information yield has been high. New control requirements have been indicated and satisfied. Tests and alinement procedures, application criteria, and auxiliary techniques have been developed. Results have been gratifying.
