This course will be particularly helpful to consultants, contractors, and to electric utility companies 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.
Overall Learning Outcomes
Day 1 – Fundamental Relations of Turbine Hydraulics
To understand how hydro systems function and are designed (Day 1)
To better appreciate design tensions and the nature of the key trade-offs (all)
To appreciate the ingenuity of the past and the challenges of the future (Day 1)
To gain valuable insight into hydro accidents so these are less likely to be repeated (Day 3)
To evaluate the key strengths and weakness of key design choices and decisions (Day 2)
To enhance both your practical and theoretical understanding and thus your career (all)
To be able to complete basic calculations and design choices (Day 2)
To network and interact with follow participants and instructors (all)
Thus, to position yourself to better exploit your next business or professional opportunity (all)
Day 1 starts with a brief summary of the strengths and challenges of hydro when viewed from a 21st century perspective. The day then focuses on the great and never-old fundamentals of flow: continuity, energy, momentum, similarity, and vibration.
The day will feature a variety of short hands-on exercises to create an active learning environment throughout. The goal is to review and consolidate the basic fluid mechanics that underlie all successful hydropower projects. Each major topic will begin with an insightful and practical review of fundament concepts, that will include application examples, and each session will provide a carefully staged confirmation exercise to keep learning active and engaged.
Day 2 – A Guided Design Workshop with Practical Examples and Applications
Day 2 is constructed as a guided step-by-step design exercise to see how the principles of Day 1 are implemented and balanced. The basic hydraulic configuration and design choices associated with a Pelton system will be progressively selected over the day, with the various approaches summarized, discussed and critiqued.
The overall goal of this day is to reveal how hydraulic, mechanical, civil and electrical interdependencies are satisfied at the basic level through key choices of penstock, turbine and generator parameters. Interspersed through the day will be worked design examples and case studies to reveal various practical challenges and choices. The approach is to actively develop a view of both the “big picture” in a hydro design along with an appreciation of how the details contribute to a successful project.
Day 3 – The Challenge and Opportunity of 21st Century Hydro (All) – a guided SWOT analysis
Day 3 is organized around a set of case studies of the best and the worst of recent hydro design experiences:
•Turbine operating diagrams and optimization
•Aging from transient events - start, stop, change load, etc
•BC Site C Clean Energy Project: “S” Shape flow at Inlet structure
•Other “S” Shape cases: Niagara Falls ON, Grand Coulee US , etc.
•Richard B. Russell Power Plant operating modes
•The Sayano-Shushenskaya Disaster in Russia in 2009 (76 dead)
• Similar accidents as of 1962: US, USSSR, Sweden, Yugoslavia etc.
•Extension in quick aging zones; accelerated age: Iron Gates 1, etc.
•Janpeg, Iron Gates 2, etc.: accelerated age
•Three Gorges Turbines Cavitation
The day focuses on achieving excellence in operation, maintenance and design and, as a counter weight to overly-optimistic expectations, a summary of the kinds of things that can happen when things go wrong.
The day is educationally constructed around a vigorous and lively SWOT analysis of hydro: that is, looking at hydro’s strengths and weaknesses leading to an analysis of opportunities and threats. This day will present published and documented examples of systems that worked well as well as those that didn’t; the goal is to expose and elucidate those critical elements in the design and construction process that contributed to success and failure.
The course will share the experience of the instructors with the goal of assisting owners, authorities and designers to better design and operate their systems at optimum conditions: with up to 10% more profit and cleaner energy production, even while providing spinning reserve to help prevent blackouts, and by simultaneously reducing risk of accidents and breakdowns. We will consider the Strengths, Weaknesses, Opportunities and Threats (a SWOT analysis) associated with modern hydroelectric plant design and operation. Learn More >
About the Course Instructors
Tihomir 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. 2006 Tim has joined Ontario Power Generation as a Senior Plant Engineer with Asset Management Department of Niagara Plant Group.
