Function and Applications

Description:

This system provides you with all the answers you need concerning the basics of using wind energy. With the help of curriculum-based experiments, it discusses different topics which are necessary for understanding the functions of wind power plants. The study of how wind speed, wind direction or rotor type influences the power output are only some examples of possible experiments. Both qualitative experiments for students from age of 11 to 13 and complete quantitative trials for physics lessons until the age of 19 are described in detail.

Experiments:

• Influence of the wind speed on a wind turbine
• Start-up wind speed at a wind turbine
• Comparison of the start-up wind speed of a Savonius and a three-blade rotor
• Change the turbine voltage by connecting a consumer
• Examine the wind speed behind the rotor
• Energy balance sheet at a wind turbine
• Calculating the efficiency of a wind turbine
• Storing electric energy
• Energy conversion in a wind turbine
• Examine color wheels using a wind turbine
• Comparison of a Savonius rotor and a three-blade rotor
• Comparison of two, three and four-blade rotors
• Characteristic curves of a wind turbine
• Influence of the wind direction
• Influence of the rotor blade pitch
• Influence of the rotor blade pitch on the start up speed of a wind turbine
• Influence of the blade shape
