Effect of High-Speed Rectifier Excitation Systems on Generator Stability Limits
TLDR
In this paper, a device to provide a signal proportional to changes in generator speed has been developed by Ontario Hydro and field tests have been performed to demonstrate that use of this signal with a high-speed rectifier excitation system results in dynamic stability limits which approximate those which can be obtained with a zero reactance generator.Abstract:
A device to provide a signal proportional to changes in generator speed has been developed by Ontario Hydro. Field tests have been performed to demonstrate that use of this signal with a high-speed rectifier excitation system results in dynamic stability limits which approximate those which can be obtained with a zero reactance generator. Transient stability limits are greater than those obtainable with high-response conventional excitation systems. Results from the field tests and a computer study are compared.read more

Excitation Control to Improve Powerline Stability
TL;DR: In this paper, the influence of generator voltage regulators on powerline stability is closely scrutinized by analog techniques and it is shown that high-speed control of excitation to maintain constant terminal voltage actually hampers rather than aids damping and power line stability.

Damping of System Oscillations with a Hydrogenerating Unit
TL;DR: In this article, the phase advance of the first derivative was used to offset the inherent lags of the hydro unit, and the scheme is proving capable in augmenting the stabilizing effort from the limited amount of suitable fast response steam capacity available.

A frequency-response method for the predetermination of synchronous-machine stability
A.S. Aldred,G. Shackshaft +1 more
TL;DR: A new concept for the predetermination of synchronous-machine stability is presented, based on the realization of a basic closed-loop pattern for a synchronous generator, which, when established, can be subjected to the frequency-response procedure of the Nyquist stability criterion.
