Entry requirements

120 credits in science/engineering, including a basic course in mechanics, Electric Power Systems and Fluid Mechanics.

Learning outcomes

After a successfull completion of the course the student should be able to:

• describe the water flow through a power station,
• perform theoretical calculations on hydropower dams and spillway discharge,
• analyse and perform calculations on hydraulic parameters for different turbine concepts and hydraulic transients occurring in the waterways,
• describe the principles of the electrical components and perform calculations of the parameters of the electrical system,
• explain voltage and turbine regulation and how these affect the electrical grid and the mechanical system with turbine and generator,
• discuss the environmental effects of hydropower installations,
• utilise the concepts in the course to analyse similar systems,
• work together in a project related to the course contents.

Content

Hydropower history and the design of a hydropower station. Dams, spillways and waterways. Meteorology and hydrology. Applied fluid dynamics. Hydraulic losses, torque on a runner blade. Turbine and draft tube. Electrical generators, the generator on the grid. Transmission of electrical power. Hydraulic transients. Regulation and dynamics. Environment and laws. Marine current power. Pumped storage hydropower. Production planning. A large scale project (eg newbuilding / renovation of a larger power station). Laborations on surges, water hammer, generators, and hydraulic losses. A group project where a hydropower station will be modelled.

Instruction

Lectures, tutorials, study visits and project work.

Assessment

Written exam (7 credits). Written and oral presentation of laboratory work (1 credits) and project work (2 credits). The presentation of the project or laboratory work should be done in English.
