A variable speed wind turbine power control
TLDR
In this article, a simple control scheme is proposed that allows an induction motor to run a wind turbine at its maximum power coefficient, using a standard V/Hz converter and controlling the frequency to achieve the desired power at a given turbine speed.Abstract:
To optimize the power in a wind turbine, the speed of the turbine should be able to vary with the wind speed. A simple control scheme is proposed that will allow an induction motor to run a turbine at its maximum power coefficient. The control uses a standard V/Hz converter and controls the frequency to achieve the desired power at a given turbine speed.read more
