The key components of a wind turbine include the blades, rotor, generator, and power transmission system. The blades are designed to capture the kinetic energy of the wind, causing them to rotate. As the blades spin, they turn the rotor connected to the main shaft.

The rotor, in turn, spins the generator, which converts the mechanical energy into electrical energy. This process involves electromagnetic induction, where the movement of the rotor within a magnetic field produces an electric current. The generator is a crucial component that transforms the rotational energy into usable electricity, which can then be transmitted through power lines for distribution.

The power transmission system within a wind turbine is responsible for regulating the speed of the rotor and ensuring that the generated electricity matches the required frequency for grid connection. By adjusting the rotation speed of the rotor, the turbine can optimize energy production based on wind conditions, maximizing efficiency and output.
