The electrical power produced by a vertical axis wind turbine / Intan Nazirah Roslan

This project was a study about a relationship of the speed of wind for the vertical
axis wind turbine with voltage output, power output and its current output as their
result. The study was using a GES-200 Wind Energy Trainer machine of a vertical
axis wind turbine equipment. A vertical axis wind turbine (VAWT) has a
perpendicular axis to the wind and vertical to the ground. The shaft rotor of the
wind turbine was vertical and the main component that is generator in (GES-28002)
was located below the blades. VAWTs can capture winds from any direction, they
do not depend on the direction of the wind thus it can produce the power easily. The
study featured of a speed of wind variable and the design of the vertical axis wind
turbine itself. Next, the GES-200 Wind Energy Trainer was used for characterise
the voltage and current characteristic curve that has been obtained by using wind
speed and the wind generators. By using the machine, the power produced has been
calculated from the voltage output and current output produced. The apparatus used
in the study was, wind energy baseplate (GES-28001) wind generator (blower),
vertical axis wind turbine (GES-28002), anemometer (GES-28004) for the speed of
wind measurement, wind energy module (GES-23001) for voltmeter and ammeter
reader and lastly was a power supply. As the result, it was found that at the highest
wind speed in Malaysia was 2.1 ms-I, the voltage output was 0.15 volts, the power
output was 0.0318 watt and for the current output was 212.0 mA. Next for the
lowest speed was 1.6 ms-1 thus resulting in 0.12 Volts as the voltage, 0.01109 watt
as the power output and 92.40 mA as current output. Furthermore, this project also
used a meteorology data of the wind speed data in Malaysia from 2012 to 2013 as
wind based for analysed and evaluated the measured of the wind data.
Recommendation was made to further study and improved the performance of the
vertical axis wind turbine.
