Field Adjustment of Hydraulic-Turbine Governors

Journal of Engineering for Power, 1961
This paper discusses certain aspects of the adjustment of hydraulic-turbine governors for stable operation on a-c networks and describes a series of field tests performed to determine satisfactory adjustment of units operating on a network of limited capacity.

Robust Decentralized Turbine/Governor Control Using Linear Matrix Inequalities

IEEE Power Engineering Review, 2002
A new scheme is presented for the robust decentralized stabilization of multimachine power systems, based on linear matrix inequalities (LMI). The proposed method is computationally efficient and can easily incorporate additional design requirements. The efficiency of this control strategy is illustrated on the IEEE 39 bus system for a variety of large

A Supersensitive Governor for Hydraulic Turbines

Journal of Fluids Engineering, 1940
Abstract A supersensitive governor is defined in this paper as one that will move the gates of a hydraulic turbine in the corrective direction by reason of a change of speed of 0.02 per cent and will then move the gates back by reason of a change of the speed back to the former speed.

Design of a Fuzzy Logic Hydraulic Turbine Governor

Control and Intelligent Systems, 2004
In this article a fuzzy logic turbine governor is designed and simulated for the control of a hydraulic turbine, together with its penstock, based on a nonlinear turbine model. The designed fuzzy logic governor can be used in hydropower plants, and may replace the commonly used classical PID turbine governors that are causing instability problems.

Parameter Identification of Steam Turbine Speed Governor System

ASME 2011 Power Conference, Volume 1, 2011
The dynamic characteristics of the steam turbine speed governor system is one of the major factor that influence the security of the power system. It has important practical significance for the security of the power system to establish the detailed dynamic model of the steam turbine speed governor system through parameter identification.

ROBUST DECENTRALIZED TURBINE-GOVERNOR CONTROL SUBJECT TO CONSTRAINT ON TURBINE OUTPUT

IFAC Proceedings Volumes, 2002
Abstract 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

Constant System Speed and the Steam-Turbine Governor

Journal of Fluids Engineering, 1940
Abstract The demand for constant system speed is a current problem of power-generating systems. Electrical stability, governor, governing-valve characteristics, and other factors play their part in the problem. In this paper only the effect the governors and governing valves have in maintaining or disturbing the system speed is discussed.
