Wind Power

Types of Wind Turbines

• A rotor that consists of 2 or 3 blades attached to a hub.

• A generator that produces electricity in the form of alternating current.

• Control and Protection system that optimizes performance and keeps the machinery operating with safe limits.

• The tower that raises the rotor off the ground.

Four Main Components Of Wind Turbines

Parts To a Wind Turbine

• Long tall towers with propellers on the top about 40 to 80 meters up in the air.

• The propellers spin around from the wind. Which turns a turbine, which creates electricity that can power many homes.

• The propellers on top are usually the same size or half the size of the height of the tower.

How is Power Produced?

• Free and efficient.• Does not release any harmful pollutants or

gases.• One of the cheapest forms of energy available

today.• Wind is a never ending resource.

Pros

• Can get damaged or completely destroyed when hit by a heavy storm.

• On an average make a sound of about 50-60 decibel.

• Production of electricity would not always remain consistent.

• rotating blades of the turbines have proved fatal for bird.

Cons

Pros and Cons

Size of Wind Turbines

• A typical turbine with a 600 kW electrical generator will typically have a rotor diameter of some 44 meters (144 ft.).

• Wind power is the fastest growing form of alternative energy.

• 40% of all generation capacity added to the electric grid came from wind energy.

• Electric utilities are adding Wind to their establishments more and more everyday.
