Adaptive Torque Control of Low Power Horizontal Axis Wind Turbine using Matlab-Simulink

Abstract

The proposed model was build with an aim to maintain constant output torque at a set-point irrespective of varying Wind speed. First a Wind turbine emulator for a Low Power Horizontal Axis Wind turbine using DC Motor was build in Matlab /Simulink then the strategy control was achieved by using Pitch angle control technique which comprises of an Integral controller and a switch .The output torque of the Wind turbine was fed to DC motor whose armature current was controlled by using a PI Controller.The Simulated result demonstrated a constant DC motor speed, armaturé Current ,armature Voltage at all permissible wind speed of the wind turbine. The developed system can be used to build a Wind Power Generation System.
