Method of generating power using wind energy to produce electricity

The principle of wind power is converting mechanical energy generated as blades rotate into electric energy via a generator

Tower	A structure supporting a Wind Power Generator
Blade	Convert wind energy into rotational kinetic energy
Hub System	Connect a principal axis with blades
Shaft, Main shaft	Transfer the rotational kinetic energy of the blade to the generator or speed accelerator
Gearbox	Convert low-speed rotation of the main axis to high-speed rotation for power generation
Generator	Converting the mechanical energy delivered from the speed accelerator to electrical energy
Yawing System	Nacelle rotation to align the blade to wind direction
Pitch system	Adjust blade angle in accordance with to wind speed
Brake	Braking device
Control System	Setting and operating to enable unattended operation of Wind Power Generator
Monitoring System	Remote control and ground-based determination of system status

>> Horizontal Axis Wind Turbine
- Wind Turbine installed parallel to the ground where the rotating axis is in the direction of the wind
- The structure is simple and installation is easy
- Yawing device is required that rotates the nacelle 360 degrees to fit in the front of the blade in the wind direction

>> Vertical Axis Wind Turbine
- Wind Turbine installed perpendicular to the ground where the rotating axis is in the wind direction
- Yawing device is not required because it is not influenced by wind direction
