On-site investigation of electrohydraulic governors for water turbines
Proceedings of the Institution of Electrical Engineers, 1977Hydroelectric generating sets controlled by conventional, mechanical, temporary-droop governors respond rather slowly to changes in system frequency and do not, therefore, realise their full potential as spinning reserves. Because of this, the electrohydraulic governor system described in this paper was developed for on-site evaluation of control ...

Compensation of the Speed Governor of a Water Turbine by the Method of Inequalities
Journal of Dynamic Systems, Measurement, and Control, 1979The method of inequalities is used to design a compensator for the speed regulation of a Francis water turbine. Apart from the improvement in regulation achieved, this paper provides a partial evaluation of the potentialities of this method of design.

ROBUST DECENTRALIZED TURBINE-GOVERNOR CONTROL SUBJECT TO CONSTRAINT ON TURBINE OUTPUT
IFAC Proceedings Volumes, 2002Abstract This paper considers the decentralized turbine-governor control design for the damping of low-frequency, inter-area oscillations in electric power systems. A time-varying model that explains oscillations caused by parametric resonance is employed to design a controller. A robust turbine-governor controller design is presented on the basis of

Electrical governors for hydraulic turbines. I. The Erelstat electric governor
1959The development of the purely electric governor is summarized. Guiding design principles are enumerated, especially as regards the use of static apparatus and the absence of rubbing contacts. The action of the Erelstat electric governor, which is mainly electronic, is described in detail and practical results are given.
