• Hidroenergetika, Semester 3, position 1

Achieving academic competence in the field of hydropower plants, equipment and hydro energy. Obtaining practical knowledge in hydropower plants designing and the content of the technical project documentation. Mastering knowledge of how to choose and calculate hydromechanical equipment installed in hydroelectric and pump stations. Developing the ability to find the optimal solution by combining a wide range of acquired theoretical and practical knowledge and using multicriteria methods. Improving individual creative abilities in performing professional design of hydro energy systems.

On successful completion of this course the students will be able to: - define, plan and organize the phases of project design, build up and operation of hydropower plants within electro energy and water supply systems, - design the optimal hydro mechanical equipment (trash racks, valves, pipes etc.), - apply the empirical data to the choice and calculation of hydraulic machinery and equipment with the aim of high efficiency operation of hydro power plants and pump stations, - analyze the transient operating regimes and unsteady fluid flow (water hammer) in various energy systems, - collect, analyze and present the calculation results, - choose the optimal solution to the specific case by analyzing more possible solutions from the point of energy and economy, - work as a part of a team as well as demonstrate their entrepreneurial skills.
