In the normal small scale wind turbine
system, there is no braking mechanism attached to it and upon subjected to high
speed wind, the wind turbine may become damage and it also poses a safety issue
to anyone standing near to it. Also, in the existing system, the voltage
produced is dependant on the wind speed and therefore it will fluctuate.
On the other hand, this innovative system
integrates a braking mechanism to the existing wind turbine (retrofitable) and
is able to regulate the voltage produced and maintain a stable voltage across
the batteries regardless of the wind speed. By using the regenerative braking
system, the excess energy generated during high velocity winds will be absorbed
by the dumping loads as to slow down the generator to a much safer level
without having to completely stall the generator. The wind generator rotation
will be automatically slowed down when the loads increased.
Due to its retrofitable feature, this
innovative system has the potential to become an add-value feature to the
existing small scale wind turbine generator worldwide particularly in countries
like Netherlands, Japan, Korea and even in Malaysia.
