Maximum Output Power Tracking of Wind Turbine Using Intelligent Control
Abstract: The Output power of
wind turbine is determined by wind speed. The Output power can be adjusted by
controlling the generator speed and pitch angle of wind turbine. When the wind
speed below the wind turbine rated, the output power of generator can be
maximized by controlling the generator speed at point of maximum power
coefficient. When the wind speed above the wind turbine rated, output power of
wind turbine will exceed the power generators rated. In this condition, the
output power of wind turbine needs to be regulated to conform to the generator
power rate. Output power of wind turbine can be regulated by adjusting the
pitch angle of wind turbine. In this paper is developed the control strategies
based intelligent control for controlling the generator speed and pitch angle
of wind turbine, so the maximum output
power tracking (MOPT) of wind turbine can be obtained at any wind speed
variations. Generator speed is controlled using PI Fuzzy Logic Controller
(PI-FLC) based Direct Field Oriented Control (DFOC). Pitch angle of wind
turbine is controlled using Elman Recurrent Neural Network (RENN). The
simulation results with Matlab Simulink shows that the both controller was
successfully regulates the output power when the wind speed above the wind
turbine rated and the output power can be maximum when the wind speed below the
wind turbine rated.
