What is the main purpose of a wind turbine?

Wind turbines harness the wind—a clean, free, and widely available renewable energy source—to generate electric power.

What benefits do wind turbines have?

Advantages of Wind Power It’s a clean fuel source. Wind energy doesn’t pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don’t produce atmospheric emissions that cause acid rain or greenhouse gasses. Wind energy is a domestic source of energy.

What is the purpose of using an electric generator in the wind energy farm?

Wind power generation means getting the electrical energy by converting wind energy into rotating energy of the blades and converting that rotating energy into electrical energy by the generator. Wind energy increases with the cube of the wind speed, therefore WTGs should be installed in the higher wind speed area.

What are the uses of wind energy?

Wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems. Wind first hits a turbine’s blades, causing them to rotate and turn the turbine connected to them.

What are advantages and disadvantages of wind energy?

Pros and cons of wind energy

Pros of wind energy	Cons of wind energy
Renewable & clean source of energy	Intermittent
Low operating costs	Noise and visual pollution
Efficient use of land space	Some adverse environmental impact

How does a windmill work step by step?

Windmills produce electricity through a series of steps. It starts with wind turning the blades. Then, the blades turn the rotor; the rotor turns the shaft; the shaft spins the generator; and the generator produces electricity.

What are the applications of wind energy?

Application of Wind Energy:

• The wind energy is used to propel the sailboats in river and seas to transport men and materials from one place to another.
• Wind energy is used to run pumps to draw water from the grounds through wind mills.

What is the purpose of wind turbines in power plants?

It’s quite simple – their purpose is to convert the abundant kinetic energy that exists in wind, to electrical energy that we can use to power everything in our lives that operates on electricity. To do so, they take an intermediate step and convert the kinetic energy in the wind to mechanical energy (spinning the turbine).

What are the advantages of downwind wind turbines?

Downwind WT have the rotor on the flow-side as shown in Fig.1.11 (b). It may be built without a yaw mechanism if the nacelle has a streamlined body that will make it follow the wind. ■Rotor can be more flexible: Blades can bend at high speeds, taking load off the tower.

How does wind affect the spin of a wind turbine?

When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.

How do yaw motors work on wind turbines?

The yaw motors power the yaw drive, which rotates the nacelle on upwind turbines to keep them facing the wind when the wind direction changes. Most turbines have three blades which are made mostly of fiberglass. When wind flows across the blade, the air pressure on one side of the blade decreases.
