Seminar Description

As the heart of every hydroelectric project, the turbomachines are enormously significant devices producing 20% of the world’s electricity, while Canada generates over 60% of its electricity using hydroelectric dams. If it is well designed, expertly installed, and carefully maintained, a turbomachine should function efficiently and effectively for many decades, i.e. for at least 50 years with overhaul maintenance after 25 years; for reversible pump-turbines 25 and 12 years respectively. Yet, mismanagement of this critical component creates challenges, failures and chronic problems of low efficiency, crippled operation and nagging operational difficulties that increase the total costs. The ability to understand and manage a hydroelectric power plant is a key to operate the plant at optimum conditions, best efficiency, and minimum costs.

Case studies:

• The Sayano-Shushenskaya Disaster in Russia in 2009 (75 dead)
• Bhira Pumped Storage Accident in 1995 (4 dead)
• Gordon M. Shrum Generating Station Replacement Project
• Three Gorges Turbines Cavitation
• Project: Design for Powerplant with Pelton Turbine
• Wind energy cleaner when supported with hydro and pumped storage;
• Etc.

Objectives

The course will share knowledge and experience that will assist authorities and designers of hydroelectric plants to operate their systems at optimum conditions with best efficiency and minimum costs.

In this regard, the main objectives of this course are to:

• communicate the shortcomings associated with traditional considerations in design and operation of turbomachines
• bring into the engineers attention recent progress
• incorporate these attributes into planning and design of hydroelectric power plants by employing representative examples

Lecture Topics

Specific topics will include a description of typical hydraulic plants and a summary of different types of hydraulic machines. Turbo-machinery applications will be introduced in the context of hydroelectric and pumped storage plants. The main characteristics of plants including the issues of rated head, discharge, speed, type and number of machines will be discussed.

Other topics of interest include:

• Efficiency coefficients, plant efficiency, velocity triangles, Euler turbomachines equation, characteristic curves, similarity laws, model and site tests, specific speed, specific diameter, 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, storage, and pump storage plants
• Small and mini plants
• Duration curves and rated flow
• Machine characteristics, classification
• Incomplete similarity, model tests
• Cavitation, draft tube flow, vortex core, vibrations, stability
• Base and peak plants. Technical and economical criteria
• Rated power, head, flow, number of units and speed
• Market demand, electricity generation and market prices
• Gross and net head, energy losses
• Model acceptance tests
• Site, commissioning, trial tests and guarantees
• Turbine control systems
• Auxiliary equipment, pumps, compressors, and systems

Deliverables

• A set of lecture notes and PowerPoint presentations
• Pejovic S., Project: Design for Powerplant with Pelton Turbine
• A set of articles published in refereed journals and/or conference proceedings

Audience

This course will be particularly recommended to the authorities including managers, engineers (from civil, electrical and mechanical disciplines), and technicians responsible for design, operation, and maintenance of hydroelectric power plants. General audiences and university engineering students interested in gaining relevant knowledge and experience are also welcome.

Instructor

Stanislav (Stan) Pejovic, Ph.D., P.Eng. – Professor, Department of Civil Engineering, University of Toronto, Ryerson University, Professor Emeritus of University of Belgrade, Serbia

Stanislav (Stan) Pejovic, was a Professor of Mechanical Engineering at the University of Belgrade, visiting Professor at the University of Singapore, Hong Kong, Sarajevo, Skoplje, Nis, to name a few. He is teaching at the University of Toronto and Ryerson University and has lectured on subjects related to energy, thermodynamics, physics, fluid mechanics, power plants, hydraulic transients, vibrations, stability, and resonance. He specializes in design, construction, commissioning, maintenance, troubleshooting and review of electric plants, hydraulic systems, pumps, turbines, and complex systems of thermal and nuclear plants. He is the author of several books. He has been designing and consulting engineer at “Energoprojekt”, Belgrade. Dr Stanislv (Cane / Stan) Pejovic is a licensed Professional Engineer in the Province of Ontario.

Tihomir (Tim) Maricic, P.Eng. – DEI Danube Engineering International

Tihomir (Tim) Maricic graduated in Mechanical Engineering from University of Nis, Yugoslavia, in 1981. After the graduation he joined the crew of the builders of Iron Gates 2 Hydroelectric Development Project. For more than 10 years, through the variety of positions he has gained substantial and wide experience in hydro equipment design, manufacturing and installation. After moving to Canada, he has used this experience in international and domestic hydro projects as a design engineer, consultant and project engineer for service and rehabilitation. In 2006 Tim has joined Ontario Power Generation as a Senior Plant Engineer with the Asset Management Department of Niagara Plant Group. Tihomir Maricic is a licensed Professional Engineer in the Province of Ontario.

Gholamreza (Bahman) Naser, Ph.D. P.Eng. – Assistant Professor, Okanagan School of Engineering, University of British Columbia

Gholamreza (Bahman) Naser is currently an assistant professor in the Okanagan School of Engineering at the University of British Columbia.

He graduated from the University of Toronto with a Ph.D. in Civil Engineering in the area of Water Resources. His Ph.D. research was focused on developing two-dimensional and multi-component computer models to guide the planning and design of a drinking water distribution system from both hydraulics and water quality points of views.

After earning his Ph.D., he spent about two years as a postdoctoral fellow in affiliation with the University of Toronto. During this time he began to expand his research area into Energy Efficient Systems and Sustainable Design through his collaboration with the Division of Environmental Engineering and Energy Systems.

For his Master thesis, he was looking at sediment transport mechanisms in open channels and rivers. Sedimentation process was coupled with a two-dimensional hydraulic model through a novel numerical scheme.

He has had the opportunity to work in the consulting industry and also to instruct courses in academia for a number of years before undertaking his Ph.D.

He is a professional engineer licensed in the province of British Columbia.
