TURBINE HYDRAULICS AND TESTING
OPTIONAL (4h)
The Turbine hydraulics option is an add-on to the Turbine basics course, it is required that the Turbine basics course be completed before the Hydraulics course can be taken.
The objectives of this course are to provide an introduction to the hydraulic aspects of turbines. Completion of this course option will provide participants with a better understanding of how the mechanical components of the turbine interact with the water flowing through the unit. Furthermore, the course will provide background on the model testing of turbines, which will allow students to better understand how and why model tests are carried out and what the objectives, limitations, and requirements are for these types of tests. The course breakdown is as follows:

The course breakdown is as follows:
- Turbine losses (1h)
- Breakdown of hydraulic losses in different unit types;
- Mitigation measures.
- Draft tube rope (0.5h)
- Physics of rope creation;
- Mitigation through aeration.
- Overpressures (1h)
- Relation between overpressure and overspeed;
- Potential mitigations and trade-offs.
- Model testing (1.5h)
- Definition of a model test;
- Requirements for model test accuracy;
- Validations obtained through testing;
- Cost and length of a model test;
- Economics of model testing.
- Alternatives to model testing.
MECHANICAL COMPONENTS
OPTIONAL (4h)
The Mechanical components option is an add-on to the Turbine basics course, it is required that the Turbine basics course be completed before the components course can be taken.
The Mechanical components course is a walk-through of the main mechanical components of a turbine. Each component will be described and explanations will be provided as to its function, inner workings (if applicable), interaction with other components and its potential variations from one unit to another.
The following base components are covered:
Any specific components not mentioned in the base components can also be covered at the client’s request.
