leXsolar-Wind Large 2.0

This system provides you with all the answers you need concerning the basics of using wind energy. With the help of curriculum-based trials, 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. For the qualitative trials, the expansion "Measurements without Measuring Tools" is required.

Experiements:

Dependence of the wind power plant on wind speed:

Hands-on experience with light bulb (only with the expansion "Measurements without Measuring Tools")

By measuring the voltage at the generator

By determining the power output of the generator using a constant

resistance (For the quantitative determination of the wind speed, the

expansion "wind speedometer" is required. Otherwise the wind speed

can only be determined using given calibration curves)

Variation of the generated voltage produced by changing the load:

With resistance

With the load's buzzer, engine and light bulb (only with the expansion "Measurements without Measuring Tools")

Analysis of wind speed in front of and behind the rotor (only possible with the expansion: Wind Speedometer)

While idle

With the load generator

Effincency determination of a wind power plant

Saving energy

Energy conversion and use of wind energy:

Studying the conversion of energy kinetic energy rotational

energy electrical energy radiation energy by the LED

Studying different energy conversions with the buzzer, engine and

light bulb (only with the expansion "Measurements without Measuring Tools"

Analysis of different rotor types

Other application tests

These additional, interesting experiments are included in the curricula but only have an indirect correlation to the subject of wind energy:
