- 3. INTRODUCTION A "wind farm" is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage power collection system. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage transmission system. A large wind farm may consist of a few dozen to several hundred individual wind turbines, and cover an extended area of hundreds of square miles (square kilometres), but the land between the turbines may be used for agricultural or other purposes.

- 6. Near shore Air borne
- 7. ON-SHORE WIND FARM It Converts kinetic energy-mechanical energy- electrical energy. Wind turbines operate on a simple principle i.e The energy in the wind turns three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy. At 30 meters or more above ground, they can take advantage of faster and less turbulent wind. Early turbines were small by today's standards, with capacities of 20-30 kW each. Since then, they have increased greatly in size delivering up to 7 MW.
- 8. OFF-SHORE WIND FARM Off shore wind farms is also called as floating wind parks. Floating wind parks are wind farms that site several floating wind turbines closely together to take advantage of common infrastructure such as power transmission facilities. A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity.
- 9. TYPES OF WIND TURBINES Most common industrial design today. HAWT have the main rotor shaft and generator at the top of a tower and must be pointed into the wind. HAWT, where wind velocities are high. Able to increase height of tower to harness higher wind velocities at higher altitudes.Horizontal Axis Wind Turbine Design Horizontal Axis Wind Turbine
- 10. Vertical Axis Wind Turbine Design VAWT have the main rotor shaft arranged vertically .The generator and gear box placed near the ground. Utilizes wind flow in all directions (360°). Constructed on buildings to avoid ground level turbulence. Vertical Axis Wind Turbine

- 16. CONCLUSION Nowadays, wind energy is developing rapidly all around the world. There are many options of wind power generation and collection system configuration. Wind energy has matured to a level of development where it is ready to become a generally accepted utility generation technology ,a brief discussion of this development is presented.
