TLDR
In this paper, the effects of specific speed governors and system characteristics on over-all system performance are investigated, under certain conditions some governors may accentuate rather than reduce the magnitudes of the frequency swings, and the conditions for which this may occur.Abstract:
In the normal steady-state operation of a power system, proper load division, frequency, and time are maintained by manual or automatic system control, while the transient swings occasioned by load changes are absorbed by the inertias and speed governors of the individual generating units. With improvements in reliability and performance of systems and their interconnections, it is a natural development that further careful attention and study be given to the basic speed governors and their effects on system operation.1,5,6 It is desirable to determine the requirements which a good governing mechanism should fulfill, and the effects of specific governor and system characteristics on over-all system performance. Moreover, under certain conditions some governors may accentuate rather than reduce the magnitudes of the frequency swings, and it is desirable to know the conditions for which this may occur.read more

Tie-Line Power and Frequency Control of Electric Power Systems - Part II [includes discussion]
TL;DR: The object is to determine theoretically the best values of controller gains, that is, to find those controller settings that will result in best over-all system performance, and stability, rather than rapidity of response, is preferred.

Optimum Adjustment of Hydro Governors on Manitoba Hydro System
TL;DR: The main criteria for stable governing as selected are that each machine will be stable when supplying an isolated load, and that the calculated speed transient following a small load change will be almost critically damped as mentioned in this paper.

Effect of Prime-Mover Speed Control Characteristics on Electric Power System Performance
TL;DR: In this article, the prime-mover speed governors function principally as stabilizers, automatic power-frequency control taking over the job of maintaining tie-line power schedules, frequency, and time.

TL;DR: During normal operation the prime-mover speed governors function principally as stabilizers, automatic power-frequency control taking over the job of maintaining tie-line power schedules, frequency, and time.
