WIND POWER

WHY WIND POWER?

A wind turbine is a device that converts the kinetic energy from the wind into mechanical energy, which is then converted into electricity through a generator.

They are designed to harness the power of the wind and contribute to clean, sustainable electricity generation. Here’s an overview of wind turbines:

HOW IT WORKS

WIND TURBINES

BLADE
ROTATION

The rotating blades are connected to a central hub, which is part of the rotor. The rotor’s rotation is driven by the wind, and the speed of rotation depends on the wind speed and the design of the turbine.

GENERATOR

The main shaft is connected to a generator located inside the nacelle. The generator converts the rotational mechanical energy into electrical energy through electromagnetic induction. In most wind turbines, an asynchronous (or induction) generator is used, which produces alternating current (AC).

ELECTRICAL
OUTPUT

The electrical energy generated by the generator is initially in the form of alternating current (AC), which is then transformed to a higher voltage level using a transformer within the nacelle. The transformed electricity is then transmitted to a substation via power cables within the tower.

WIND
CAPTURE

Wind turbines are strategically placed in locations with consistent and strong winds. As the wind blows, it flows over the turbine’s blades, creating a difference in air pressure between the windward (front) and leeward (back) sides of the blades. This pressure difference causes the blades to move, similar to an airplane wing, but in a circular motion.

MECHANICAL
ENERGY

As the rotor spins, it transfers mechanical energy to the main shaft. The main shaft is connected to the rotor and extends down into the nacelle, the housing at the top of the tower.

CONTROL
SYSTEMS

The wind turbine is equipped with control systems that monitor various parameters, such as wind speed and direction, rotor speed, and power output. These control systems adjust the orientation of the turbine (using the yaw system) and the pitch of the blades to optimise energy capture and ensure safe operation.

GRID
INTEGRATION

In most cases, the electricity generated by the wind turbine is transmitted to the grid network, where it can be distributed to homes, businesses, and other consumers.

BENEFITS OF

WIND TURBINES

Clean Energy

Wind turbines produce clean, renewable energy without emitting greenhouse gases or air pollutants during operation.

Reduced Carbon Footprint

Wind energy helps reduce reliance on fossil fuels and contributes to the reduction of carbon emissions.

Energy Independence

Wind turbines diversify the energy mix, reducing dependence on imported fossil fuels.

Job Creation

Wind turbine manufacturing, installation, maintenance, and operations create jobs in various sectors.

Scalability

Wind turbines can be scaled to match energy demand, making them suitable for various applications, from residential use to large-scale wind farms.

Low Operating Costs

Once installed, wind turbines have relatively low operating and maintenance costs compared to traditional fossil fuel power plants.
