Bánki-Michell turbine set and its maximum power point control
Marčok, Samuel ; Baculák,, Tibor (oponent) ; Červinka, Dalibor (vedoucí práce)
This master’s thesis focuses on maximalization of power point of Bánki-Michell turbine and asynchronous generator set in small hydroelectric powerplant with the use of frequency converter. The first chapter addresses the history, division, and construction of hydroelectric powerplants. The following two chapters describe mechanical and electrotechnical equipment that is necessary for correct design of the control. The fourth chapter describes control possibilities of asynchronous generator and Bánki-Michell turbine set. As a verification of correctness, master´s thesis involves simulation in Matlab-Simulink. Results of this simulation are addressed in the fifth chapter, where systemic behaviour in selected control approach with the maximum power point of the set is considered. The most extensive chapter is the sixth one, because it depicts detailed description of measurement in speed or torque control. Last chapter summarizes and compares measured dependences with expected systemic behaviour derived from simulation. The conclusion of this thesis raises another possibilities for improvement of water potencial usage and describes the contribution of frequency converter.
