Shiga Univ. sets up wind turbine generator on campus

The School of Engineering at the University of Shiga Prefecture in Hikone City, Shiga Prefecture, has installed a wind turbine generator for research and experiments on campus. The school has started studying its usefulness by combining it with a hybrid power system that is conjugated with a single-crystalline silicon solar cell, also kept on campus.
The wind turbine generator features a power generator drum with a permanent magnet implanted in it. It also has three rotor blades fastened by bolts. The rotor blade measures 5.1 meters in diameter and 15 meters in height. It weighs 190 kilograms and its output is 5 kilowatts. It starts rotating when the wind speed reaches 3 meters per second.
When the speed of the wind exceeds 14 meters per second, the rotor axis is shifted out of the wind direction to control the rotor speed and continue generating electric power. It is designed to withstand the wind speed of 60 meters per second.
Wind turbine generators are generally set up on shorelines exposed to strong winds. The university is situated in an inland area noted for having strong winds. Thus, expectations are placed on the university for yielding results.
