“A wind turbine is a device that converts the kinetic energy of wind into mechanical energy, which is then converted into electricity. It is a renewable energy technology commonly used to generate clean electricity from wind resources.
How a wind turbine works:
Blades: The wind turbine has large, aerodynamic blades mounted on a rotor. The blades are designed to capture the energy from the wind.
Wind Energy Conversion: When the wind blows, it exerts a force on the blades, causing them to rotate. The energy from the moving blades is transferred to the rotor.
Rotor and Shaft: The rotor is connected to a shaft, and as the rotor turns, the shaft also rotates.
Generator: The shaft is connected to a generator at the other end. Inside the generator, the rotational motion of the shaft is converted into electricity through the principle of electromagnetic induction.
Electricity Generation: The generator produces alternating current (AC) electricity, which can then be transmitted through power lines to homes, businesses, and industries for various uses.
Control System: Wind turbines are equipped with a control system that can adjust the orientation of the blades and the yaw (direction the turbine faces) to optimize the energy capture based on wind direction and speed.
Grid Integration: Wind turbines are often part of larger wind farms that are connected to the electrical grid. The electricity generated by the turbines is integrated into the grid and contributes to the overall power supply.
It’s important to note that wind turbines require consistent and sufficient wind speeds to operate efficiently. They are typically installed in locations with favourable wind conditions, such as open plains, coastal areas, or elevated terrains. Wind power is considered a clean and sustainable energy source as it produces no greenhouse gas emissions or air pollutants during operation.
