CONTROL OF STEPPER MOTOR IN WIND TURBINES FOR OPTIMUM POWER GENERATION

Abstract

Renewable energy is a very important topic to study to find new sources of energy to produce electricity. The main advantages of renewable energy are available, clean, low cost and continuous energy. This project investigates wind energy system in general form, which is a part of renewable energy. The aim of this thesis is to design a maximum power point tracking for wind turbine. This study concentrates in control of turbine blades throw control in position of the blades to face the wind and take the maximum energy from it. The control in position of blades done by microcontroller, stepper motor and appropriate speed sensor. In this study we will use optical sensor to enter the wind speed to the microcontroller which direct the stepper motor in the appropriate angle. Wind turbine blades was installed in the top of the stepper motor, by moving the stepper motor to the appropriate angle the blades also move to the appropriate position.
