Project Summary

Our project is Design and development of wind turbine based power generation system,basically in this project we able to degisn and develope wind energry. As we know that wind energy is a source of renewable energy. It does not contaminate, it is inexhaustible and reduces the use of fossil fuels, which are the origin of greenhouse gasses that cause global warming. Wind energy, the world's fastest growing energy source, is a clean and renewable source of energy. In todays world wind is one of the cheapest and cleanest energy source.Wind energy (or wind power) refers to the process of creating electricity using the wind, or air flows that occur naturally in the earth’s atmosphere.Around 2 billion people are living their lives without electricity a similar number remain dependent on fuels such as animal dung, crop residues, wood, and charcoal to cook their daily meals.We are looking for a solution that is environmentally friendly, reliable, economically feasible and cost effective. there are two key parameters of wind  are 

1.speed

 2.Direction

Anemometry is the process of measuring wind speed atheExpected hub height of wind turbine. The sensors used for Wind speed measurement is called anemometer.A device mounted on a vertical shaft which is free to rotate and changes in direction with the wind is called Wind Direction Measurement- Wind Vane.  Our project is hardware based Implementation of wind turbine system that is connected to the distribution system through transmission system.This project focuses the wind power and its potential that can be harnessed in the future to meet the current energy demand.  Its help to Increased efficiency and smooth operation is obtained by using power electronic circuitries like thyristor and converters.

Project Objectives

We have 5 main objective of our project Design and development of wind turbine based power generation system 

1.Harnessing wind to produce Power by using control systems to obtain the maximum output from the wind by tracking its direction and direct the wind turbine to it. 
2.Power supply in Remote/Raw Weather Areas
3.Eco Friendly Production of electricity with longer sustainibility of power generation system

Project Implementation Method

Our project is to design and implement a small-scale model of the actual size of an industrial wind turbine to produce electrical energy to use it in hoses and farms. Also, we have used control systems to obtain the maximum power from the wind by tracking its direction and directs the wind turbine to it.

It consist of rotor blades which rotate around a horizontal hub. The hub is connected to a gearbox and generator, which are located inside the nacelle. The nacelle houses the electrical components and is mounted at the top of the tower. In a grid-tied configuration the electricity from the generator is routed to an inverter which converts the electricity from direct current (DC) to the alternating current (AC) that electrical grids use.

System operation of wind turbine is when the rotor begins to rotate (spin) after the wind speed reaches, the battery charging commences at a slightly higher speed, depending on the battery state of charge. Then when the battery is fully charged, the charge controller disconnects the turbine from the battery. The turbine will produces a three phase alternating current (AC) that varies in voltage and frequency as the wind speed varies. Next ,the controller (regulator) rectifies this AC into the direct current (DC) required for battery charging and controls the energy supplied to the batteries to avoid overcharging.

In the wind turbine systems, the turbine is allowed to rotate at different speeds with the varying wind speed. It is usually desired to ensure optimum power transfer. The actual speed of rotation is determined by the torque versus speed characteristics of both the turbine and the generator. In the operating mode, major control means are inevitably placed on the electrical side. Obviously, the control of electrical systems is easy to implement, more reliable and less costly than the control of mechanical systems. In addition, synchronous machines may be used in variable shaft speed. In this case, operation of the system at the most efficient working condition is possible.

Technical Details of Final Deliverable

A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical

Energy. If the mechanical energy is then converted to electricity, the machine is called a wind

generator, wind turbine, wind power unit (WPU), wind energy converter (WEC), or aero generator.

Wind turbines can be separated into two types based by the axis in which the turbine rotates.

Turbines that rotate around a horizontal axis are more common. Vertical-axis turbines are less frequently used.

Wind Turbines have the main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind. Most have a gearbox, which turns the slow rotation of the blades into a quicker rotation that is more suitable to drive an electrical generator.Since a tower produces turbulence behind it, the turbine is usually pointed upwind of the tower.Turbine blades are made stiff to prevent the blades from being pushed into the tower by high winds. Additionally, the blades are placed a considerable distance in front of the tower and are sometimes tilted up a small amount.Downwind machines have been built, despite the problem of turbulence, because they don't need an additional mechanism for keeping them in line with the wind, and because in high winds the blades can be allowed to bend which reduces their swept area and thus their wind resistance.

Since cyclic (that is repetitive) turbulence may lead to fatigue failures most turbines are upwind machines.

• Wind speed

The amount of energy in the wind varies with the cube of the wind speed, in other words, if the wind speed doubles, there is eight times more energy in the wind .

). Small changes in wind speed have a large impact on the amount of power available in the wind.

• Density of the air

The more dense the air, the more energy received by the turbine. Air density varies with elevation and temperature. Air is less dense at higher elevations than at sea level, and warm air is less dense than cold air. All else being equal, turbines will produce more power at lower elevations and in locations with cooler average temperatures.

• Swept area of the turbine

The larger the swept area (the size of the area through which the rotor spins), the more power the turbine can capture from the wind. Since swept area is , where r = radius of the rotor, a small increase in blade length results in a larger increase in the power available to the turbine.
