Students are expected to have completed
All first and second year subjects. Among them, Electrical Power Engineering Fundamentals is of utmost importance. Furthermore, it is desirable to have followed "Electric Power Generation" in the first term of the third year.
Competences and skills that will be acquired and learning results. Further information on this link
Students who successfully complete this course will be able: - to summarize the history of modern wind turbines justifying the current technology development. Moreover, students should employ the exact components terminology for the most common applications including, large onshore and offshore schemes as well as small wind turbines. - to compute the basic wind measurement statistics and understand the resource assessment process. - to understand and use the fundamental physics equations that allow to convert wind energy into mechanical and electrical energy. - to describe all wind turbines types and justify their main characteristics. Moreover, students should understand the main mathematical models for the most relevant types, with special emphasis on the different control strategies. - to identify the main wind turbine manufacturers, as well as to properly analyse and compare their technical specifications. - to understand the main impact from high penetration levels of wind energy, and the main aspects of the grid codes developed to mitigate them. - to understand results from dedicated software packages that model wind turbines for economic assessment or power systems analysis. - develop the capacity to work in a team and promote creative team interaction to encourage contribution from all members so as to deliver specific engineering projects and assignments
