Description

The RE12 Advanced Wind Energy system provides students with a self-contained modular system, covering the physical fundamentals of wind energy productions, covering wind power fundamentals, controlling a typical wind tunnel and different rotor types. 

Using the system students study wind turbine characteristics, turbine performance under load and turbine performance at different wind conditions. 

This is achieved by practice experimentation designed to analyse the power conversion processes at a wind turbine, characterising and rating of a typical wind turbine, investigating the influence of wind conditions and loads on turbine performance and determining optimized working conditions. 

The system is supplied with multiple rotors allowing student to investigate Savonius rotors, blade shape, blade number and operating conditions. Detailed experiments are provided allowing the student to understand the advantages and disadvantages of different rotor types ultimately proving the argument that a three-blade horizontal axis wind turbine is the most efficient design.
