What is a wind turbine & how does it work?

A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year.

What is a wind turbine used for?

Smaller wind turbines are used for applications such as battery charging and remote devices such as traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid.

How are wind turbines classified?

Wind turbines are classified by the wind speed they are designed for, from class I to class III, with A to C referring to the turbulence intensity of the wind. Conservation of mass requires that the mass of air entering and exiting a turbine must be equal.

Where can wind turbines be built?

Wind turbines can be built on land or offshore in large bodies of water like oceans and lakes. The U.S. Department of Energy is currently funding projects to facilitate offshore wind deployment in U.S. waters. Modern wind turbines can be categorized by where they are installed and how they are connected to the grid:

Spherical wind blade power generation

FAQS about Wind power generator principle

How does a wind turbine generator work?

The fundamental principle behind wind turbine generators is relatively simple and consists of four primary steps. First, when the wind blows, it applies a force to the turbine blades. This force makes the blades rotate around a rotor, which is connected to the main shaft.

How does a wind turbine turn mechanical power into electricity?

This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.

The fundamental principle behind wind turbine generators is relatively simple and consists of four primary steps. First, when the wind blows, it applies a force to the turbine blades.

How much power does a wind turbine produce?

Most large turbines produce their maximum power at wind speeds around 15 meters per second (33 mph). Considering steady wind speeds, it's the diameter of the rotor that determines how much energy a turbine can generate.

Why do wind turbines produce more power than fixed speed generators?

In theory, some wind turbine generators may be used to compensate the low power factor caused by neighboring consumers. In economic terms, variable speed wind turbine can pro‐duce 8-15% more power than fixed speed counterparts .

What type of generator is used in a wind turbine?

For medium and large wind turbines (WTs), the doubly-fed induction generator (DFIG) is currently the dominant technology while permanent-magnet (PM), switched reluctance (SR) and high temperature superconducting (HTS) gener‐ators are all extensively researched and developed over the years.
