The aim of the diploma thesis is to measure and subsequently to evaluate microturbine characteristics. This is a new type of turbine, which was designed in the diploma thesis and is based on the theory of waterwheels. It is designed for low heads and low flow, where conventional turbines are not suitable. Taking advantage of this low heads area will be very important in the future as the hydroenergetic potential is getting gradually exhausted. The turbine has two ways of regulation - turning blades and shifting the drawer. In the first phase, two complex measurements were performed. The next step was to process the measured data gradually in three programs. The result is the rendering of the characteristics that describe the hydraulic parameters of the turbine. The last chapter shows the design proposals for automatic regulation.

The theory of deterministic chaos has generated a lot of interest and continues to be one of the much-focused research areas in the field of dynamics today. This is due to its prevalence in essential parts of human lives such as electrical circuits, chemical reactions, the flow of blood through the human system, the weather, etc. This thesis presents a study of the Lorenz equations, a famous example of chaotic systems. In particular, it presents the analysis of the Lorenz equations from stability to chaos and various bifurcation scenarios with numerical and graphical interpretations. It studies concepts of non-linear dynamical systems such as equilibrium points, stability, linearization, bifurcation, Lyapunov function, etc. Finally, it discusses how the Lorenz equations serve as a model for the waterwheel (in detail), and the convection roll for fluid.

This diploma thesis discusses the issue of finding type of water turbine for very low heads and low discharges, which could be operated as mobile micro hydropower plant in island mode. Thesis deals with summary of appropriate choices of water turbine for needs of micro hydropower plant. Essential part of diploma thesis deals with design of optimized waterwheel. Waterwheel was chosen because commercial high-speed turbines have low efficiency for low heads. Waterwheel was manufactured and measured in laboratories of Fluid engineering. Measurement output was discharge and efficiency characteristic of turbine. The price calculation was made after manufacture.
