- 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
