IEEE Transactions on Power Systems, 2015
Due to substantial use of gas turbines and their highly dynamic behavior, they have a profound impact on electrical grid. Although the control philosophies of various turbines are almost the same, there are some nuances in governor systems. As long as these details affect system response in extremely dynamic phenomena such as load rejection, they ...

Electric governor of Kaplan turbines
Hydrotechnical Construction, 1981The preceding method of controlling the runner blades of a Kaplan turbine has a number of advantages compared to the hydromechanical method and it should be introduced both at hydrostations being put into operation for the first time and when modernizing operating hydrostations by replacing the mechanical drive system of the runner blades by an ...

Operating Characteristics of Turbine Governors
Transactions of the American Institute of Electrical Engineers, 1930Surging has occurred on power systems whose transmission distance is small and load density high. The Duquesne Light Company of Pittsburgh, Pennsylvania, has experienced these surges. This paper outlines tests conducted to determine the influence the steam turbine governors have in starting or sustaining a surge condition.

Journal of Fluids Engineering, 1940
Abstract This paper has been prepared as a contribution to a symposium on the subject of steam-turbine governors. The importance of the subject at present arises more from the increasing complexity of interconnection requirements than from any definite deficiency in existing apparatus.

Design of a Fuzzy Logic Hydraulic Turbine Governor
Control and Intelligent Systems, 2004In 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.

Identification of turbine engine dynamics with the governor in the loop
2016 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2016Precise gas turbine engine control for dynamic processes is of great importance in industry. To be able to preciously control the turbine engine an accurate model, which can predict the engine dynamic responses is required. This work focuses on developing a new prediction model for turbine engine rotor speed in a dynamic situation (time-varying rotor ...

Proceedings of the Institution of Mechanical Engineers, 1953
In this paper is presented a general picture of closed-sequence system controls of hydro-electric plants, covering the relation between water-turbine governors and water level, power, frequency and tie-line controls. Special mention is made of the difficulty of governing created by the inertia of the water in the pipe-line.
