Seminar Description

The turbo machine at the heart of every hydro project. If is well designed, well chosen, expertly installed and well maintained, it can be expected to function efficiently and effectively for many decades, i.e. for at least 50 years with an overhaul mainteance after 25 years; for reversible pump-turbines 15 and 8 years respectively. Yet mismanagement of this critical component creates challenges, failures and chronic problems of low efficiency, crippled operation and nagging operational difficulties. This course overviews and highlights the function, operation, performance, selection of turbo machines for hydroelectric applications. Specific topics will include a description of typical hydraulic plants and a summary of different types of turbines. Turbo-machinery applications will be introduced in the context of hydroelectric and pumped storage plants. The main characteristics of plants and hydraulic machines including the issues of rated head, discharge, speed, type and number of machines will be discussed.

Other topics of interest will include:

• efficiency coefficients, plant efficiency, velocity triangles, Euler turbomachines equation, characteristic curves, similarity laws, model and site tests, specific speed, vibrations, cavitation of hydraulic turbines, pump/turbines; plant cavitation coefficient, pump/turbine cavitation coefficient, variable speed machines
• Estimation of main dimensions of machine units, machine house, waterways, electrical and civil structure; transients and stability
• Layout of hydroelectric and storage plants
• Pump storage electricity
• Major and auxiliary equipments and systems
• Small and mini plants
• Types of projects
• Case studies
