How Wind Turbines Convert Wind into Electricity

In modern times, we popularly use wind turbines to make wind a renewable energy source for our daily lives. This started long ago when humans filled sails and shaped landscapes with the help of wind. From the beginning days of human civilization, the wind has acted as both a friend and foe.

Wind turbines harness the unseen power of the wind, it convert the kinetic energy of the wind into electricity. Wind power has emerged as an alternative as the world constantly seeks to transition away from fossil fuels. Wind Power Generation offers a sustainable and environmentally friendly solution to our energy needs. India is a hub for wind manufacturing and has generated 4907.58MU in Feb 2024, which is expected to grow further.

In this article, we will look into how the electricity from wind turbines is generated and also what are the specific challenges that need to be addressed during it.

Types of wind turbines:

Before diving into the entire energy conversion process, let’s first look into the types that are generally being used in the industry. They come in various shapes and sizes, each with its unique features and advantages. However, the two primary types are:

1. Horizontal-Axis (HAWTs)

● Widely used: HAWTs are the widely used type of wind turbine in the industry due to their efficiency and reliability.

● Rotor orientation: The rotor axis of HAWTs lies horizontally, allowing the turbine to capture wind from any direction.

● Tower support: These are generally seen installed in tall towers to capture more wind.

2. Vertical-Axis (VAWTs)

● Alternative structure: Contrary to HAWTs, VAWTs have a vertical rotor axis which makes them less dependent on the wind direction.

● Types: The two common VAWT designs include the Darrieus and Savonius turbines.

● Advantages: VAWTs can be installed in tight spaces and are less likely to be harmed by certain environmental factors.

How do they help in wind power generation?

The very fundamental explanation of the working principle of a wind turbine is the wind tends to turn the propeller-like blades of a rotor, which spins a generator. As a result of the generator, electricity is produced. Wind flow and speed vary across the country and are affected by various other environmental factors.

More about wind

The next thing coming to your mind could be then what type of energy is wind. Well, the answer to this is that wind is a form of solar energy caused by these three mechanism.

● The irregular heating of the sun in the atmosphere.
● Unevenness of the earth's surface.
● The continuous spinning of the earth.

Understanding wind turbines further

It is a complex machine designed to utilize the power of the wind. It consists of several key components:

Basic Components:

● Blades: These are long aerodynamic-shaped structures that capture the wind's kinetic energy and convert it into rotational motion.

● Rotor: It is that point where the assembly of blades and a hub that rotates on a vertical axis are seen.

● Nacelle: The housing that sits at the top of the tower and contains the generator, gearbox, and other components.

● Tower: This is the ultimate structure that supports the nacelle and rotor. It elevates them to a height where they can access stronger and more consistent winds.

● Generator: The device that converts the rotational motion from the rotor into electrical energy.

Functioning of the generator

The generator is the most crucial component of a wind turbine. Generally, a synchronous generator is used, which means it produces alternating current (AC). As the rotor starts spinning, it induces a magnetic field in the generator's stator. This contact between the rotating rotor and the stationary stator generates electricity.

The generated electricity is then transmitted through cable wires to a substation, where it is transformed and distributed to the electrical grid for domestic usage.

Challenges with the wind turbine setup

While wind energy are driving the energy revolution provides numerous advantages, it also presents challenges that need to be addressed.

● Unpredictable nature: Wind is a variable natural resource, meaning its availability can fluctuate over time.

● Manual effort to store energy: Energy storage systems such as batteries, pumped hydro storage, and compressed air energy storage are used to store excess wind energy during periods of high production. The same stored energy is released during periods of low production. This is a continuous manual process that occasionally decreases efficiency.

● Noise emissions: Wind turbines are noisy, primarily due to the blades interacting with the wind
