Mechanical Design, Operation and Maintenance of Hydraulic Machinery

Fundamental principles in machine and component construction based on hydraulic conditions. System dynamics and governing stability will be covered, along with flow charts for the relevant processes and sequences for operation (start up, synchronization, etc). Field measurements are covered including efficiency measurements. Model efficiency measurements and scale-up to prototype values are covered. Insights into maintenance and auxiliary equipment. along with reversible pump turbines and energy storage in pumped hydro plants. Life cycle assessment of hydropower plants and will be shown. The course might be adapted extending this description.

The course provides the student with knowledge about: - The mechanical equipment in hydropower plants, dimensioning of gates, valves, trash racks and cooling-and bilge system - Operation and maintenance - System dynamic simulation methods for water hammer, surges and governor stability - Hydraulic measurements in field and in the laboratory Knowledge The course gives the student insight about: - The mechanical equipment in a hydropower plant - Operational issues Skills The course should enable the student to: - Choose adequate equipment and give basis for technical-economical analysis - Simulate hydropower plants as regards system dynamics - Carry out measurements of efficiency, flow pressure, pressure transients etc. General competence The course should give the student: - Competence regarding hydropower plants mechanical equipment - Competence on the turbine’s interaction with the hydraulic conduit system, as well as with the generator and grid.

Lectures and group work. The lectures and exercises are in English when students who do not speak Norwegian take the course. If the teaching is given in English the Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments. If less than 5 students are registered the course will be given as self-tuition.
