| Summary | This course gives students a technical understanding of fixed and floating wind turbines, tidal energy converters, and wave energy converters. From an understanding of the physics (aero, hydro, structural and dynamic), students will be able to evaluate the performance of devices and be able to compare the relative effectiveness of different designs. The course will answer questions including why most wind turbines are 3 bladed lifting aerofoils, why wave devices like resonance (except in storms), and how to anchor a tidal turbine to a rocky seabed. The modelling section will introduce appropriate tools introducing: the dynamic modelling of wave energy converters; blade element modelling of wind turbines; this will extend this to consider tidal turbines. The course makes use of the NREL software packages WEC-SIM and OpenFAST and gives the building blocks of use of these tools in later modules. |
| Course description |
History of wind energy devices. Overview of modern wind turbine sub-systems. Horizontal and vertical axis turbines. Concepts of tip speed ratio and coefficient curves. Pitch and speed control for power and thrust control.
Introduction to wave energy, including a quick recap on the resource, a description of the major Wave Energy Converter (WEC) concepts that have been proposed to date, and a quick explanation of different Power Take-Off (PTO) systems. Introduction to the frequency-domain and time-domain modelling of wave energy converters, including the derivation and solution of the equations of motion for a simple heaving buoy WEC. Description of the optimal (complex-conjugate) control of a WEC as well as other control strategies. Workshops on the modelling of two different WEC devices using the WEC-Sim software.
Fluid dynamics theory for wind and tidal turbines. Application to tidal turbine design. Understanding choice of aerofoil including lift, drag, chord and twist and consequences for coefficients of power thrust and torque. Modification of OpenFAST for use in tidal turbines. Examples using the software. Design study of a river turbine (including mooring calculations) and multiple use cases.

Learning Outcomes
On completion of this course, the student will be able to:
- Apply knowledge of the design requirements for wind or tidal turbine rotors including using methods for calculating loads and performance.
- Perform basic frequency-domain and time-domain modelling of Wave Energy Converters (WECs), as well as understand optimal control strategies applied to WECs.
- Explain how a modern wind turbine operates to maximise energy capture and reduce loads.
- Understand suitable software tools for the aerodynamic/ hydrodynamic modelling of wind, wave and tidal devices.
