The main components of a horizontal-axis wind turbine include the blades, pitch system, nacelle control cabinet, generator, gearbox, braking system, and tower.
The blades are the units that capture wind energy, converting the kinetic energy of the air into the mechanical energy of the rotating rotor. The pitch system adjusts the blade pitch angle, ensuring the blades remain in the optimal state for energy capture across varying wind speeds. The nacelle control cabinet serves as the central hub for signal monitoring and control. The generator converts the mechanical energy from the rotating rotor into electrical energy. The gearbox transmits power from the rotor to the generator, enabling it to achieve the required rotational speed. The braking system applies the brake to the turbine in response to commands. The tower acts as the support structure for the nacelle and also serves as an access route for maintenance.
The power generation equipment component industry encompasses an entire upstream and downstream supply chain; its development is influenced by factors such as overall operational performance, technological capabilities, and market competition.
