Modelling and simulation of small hydroelectric power plants

Importance of small hydroelectric power plants have been increasing more and more because of fast increasing electrical energy demand. Hence, operation conditions and constructible possibilities of the plants must be determined. In this thesis, the role of small hydroelectric power plants in hydroelectric energy production of Turkey has been investigated. In order to carry out load-frequency control of small hydroelectric power plants in computer environment, the models of turbine, generator, and governor have been generated. Small hydroelectric power plant model has been then obtained by being combined these models. Hydroelectric power plant models having linear and nonlinear turbines have been acquired the variations of power and frequency with respect to time by being operated for different load values. In addition, the small hydroelectric power plant in Elazığ has been modeled by being taken into consideration its real plant parameters as well and ultimately presented load-frequency control.
