An Influence of a Current Compounding on the Behavior of a Synchronous Generator With a Brushless Excitation System During a Terminal-voltage Variation

Brushless excitation systems of synchronous generators provide non-contact transfer of the excitation power to the generator rotor in case absence of a commutation in rotor circuit. Such systems have a long response time of terminal-voltage regulation caused by the additional rotating machine (exciter). Using of fast-acting compound circuit allows improving dynamic parameters of terminal-voltage regulation in modes of sharp voltage variation and short circuit in line.

An Analysis of the Modes of Initial Excitation of Turbogenerator on the Hybrid Real-time Model of a Power Generation System

The transient electromagnetic processes in the power generation system with turbo- generator and brushless excitation system in a mode of initial excitation of turbo-generator are analyzed in the article. The research was carried out in the hybrid system that combines a computer model of a power part with the real excitation controller. The influence of setting the automatic control system on quality of voltage regulation and generator excitation current regulation is analyzed.
