| Course contents : | In the context of sustainable development, concepts linked to promoting available hydraulic energy are explained from a technical, economic and environmental point of view.
The course deals with the description, dimensioning and management of hydroelectric power stations, focusing on the concept of hydrology, fluid mechanics, hydrodynamics of water courses and supply and drainage mechanisms.
The economic justification for production is examined and compared to other sources of energy. In particular, the problem of financial viability and development in the medium to long term is studied.
After describing the various types of installation (high, medium and low head), consideration is given to the choice of sites and evaluation of the available potential. The following concepts will then be studied :
Quality control and homogenisation of pluviometric data. Maximisation of information on flow using probabilistic models. Statistical analysis of annual and monthly flows. Classification of flow curves in a water course.
- Reminder of useful concepts in permanent and non-permanent free surface flow analysis and under pressure.
- The power of a water course, load loss, energy recuperation
- Productivity, installed flow, management method (annual, seasonal, daily)
- Accumulation devices, water intake, loading and discharge processes,
- History and operating principles of turbines: energetic assessment, Francis turbine, Pelton turbine, Kaplan turbine, bulb groups, typical curves
- Concepts of pumps and volumetric machines
- Air-chamber devices (surge tank...)
- Cavitation
- Technical-economic analysis of stations in the context of encouraging renewable energy. Social and environmental impacts. Planning and carrying out work.
The course will also include a practice piece of work on a hydroelectric development, choice of flow equipment, economic analysis, impact analysis, structural dimensioning.
The theory courses will be illustrated by a description of concrete studies and creations, completed by a visit to the Laboratoire de Construction Hydraulique where large-scale hydroelectric projects which are currently at the model development stage will be explained. A field trip to notable installations is also planned. |

| Course objective : | The main objective of this course is to tackle in a critical manner the ways in which available hydroelectric energy is used within the context of current sustainable development. This will be done using the subjects covered during the Civil Engineering Constructions course.
As well as lectures and practical sessions, these objectives will be met through lab and site visits. |
|
| Prerequisites : | Basic Hydrology course (basic grasp of hydrostatics and hydrodynamics in rivers and under pressure), basic grasp of fluid mechanics. |
|
| Organization : | Lectures and practical sessions (either in tutorial sessions or not).
The course takes place on Tuesday mornings in the first semester. Between 1330 and 1530, elements linked to hydraulic machines will be tackled (Prof. Leonard). Between 1600 and 1800, the course will deal with other aspects of hydroelectric development (Prof. Pirotton and Dr. Erpicum).
1-day field trip to visit notable installations and the scale models at the Laboratoire de Constructions Hydrauliques. |
