A 8051 based wind
turbine model consist of a moving rotor assembly consisting of a DC motor including the blades for
converting wind energy to low speed rotational energy. The generator component
includes the electrical generator, the control electronics, and most likely a gearbox
(e.g. planetary gearbox, adjustable-speed drive or continuously variable
transmission) component for converting the low speed incoming rotation to high
speed rotation suitable for generating electricity.
The whole generator system is mounted on a stepper motor configuration which
enables the system to move 180 ͦ towards
left and 180 ͦ towards right direction. This
enables the system to move 360 ͦ and
choose the direction of the wind anytime. This eliminates the dependency of
wind turbine on the direction of wind.
The system is connected with a controlling keypad to move the stepper motor in desired
direction. At the base of the turbine tower is a energy storing system made of resistors and capacitors to store
the AC voltage produced during the rotation of turbine blades. The capacitor stores the fluctuating
voltage and converts it into constant voltage supply to drive LED or other kind
of load.
An LCD is
provided along with keypad to display the condition of wind speed depending on
the speed of the moving blades. The LCD also displays the degree at which the
turbine system mounted on stepper motor is moving.
The system is connected with an Atmel 89S52 microcontroller which
controls and manages the working of whole assembly including stepper motor,
keypad and LCD display.
Key features of this project are:
Ø
A DC motor is used to generate the power from
moving wind.
Ø
Capability of turbine to rotate in 360 ͦ direction to choose the optimum direction
of flowing wind.
Ø
Controlling of system using a keypad present at
the base of the tower.
Ø

mechanism and stepper motor controlling mechanism.
Ø
The microcontroller and LCD works on a +5V
supply.
