How strong is the wind when turning the generator fan

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. When wind flows across the blade, the air pressure on one side of the blade decreases.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

A wind turbine works like a fan but in reverse: instead of using electricity to make wind like a fan, wind turbines use wind to make electricity. The wind turns the turbine's blades, which spin a shaft connected to a generator to make electricity.

Wind (moving air that contains kinetic energy) blows toward the turbine's rotor blades. The rotors spin around, capturing some of the kinetic energy from the wind, and turning the central drive shaft that supports them. Although the outer edges of the rotor blades move very fast, the central axle (drive shaft) they're connected to turns quite .

Wind turbine power output is variable due to the fluctuation in wind speed; however, when coupled with an energy storage device, wind power can provide a steady power output. Wind turbines, called variable-speed turbines, can be equipped with control features that regulate the power at high wind velocities.

6 FAQs about [How strong is the wind when turning the generator fan ]

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.

Do wind turbines have cooling fans?

Wind turbines that are used for power generation have numerous applications for cooling fans. Although fans are fundamentally selected on the basis of volumetric air flow, static pressure and size, numerous other factors must be considered for wind turbine applications.

How does a wind generator work?

A wind generator then converts the mechanical energy to electricity1. The generator is equipped with fan blades and placed at the top of a tall tower. The tower is tall so that high wind velocities can be easily harnessed without being affected by turbulence caused by obstacles on the ground, such as trees, hills, and buildings.

Do wind turbines have to be upwind to generate electricity?

VAWTs do not have to be upwind to generate electricity. Vertical-axis wind turbines can be much smaller than their horizontal counterparts. Standing only five meters (15 feet) tall, these VAWTs can be installed on the roofs of buildings. Turbines cannot operate at every wind speed. If winds are too strong, they can be damaged.

Why is wind power variable?

What happens if a wind turbine is too strong?

If winds are too strong, they can be damaged. Therefore, the turbine has an automatic controller that turns on when winds are blowing at prime speed for generating electricity. This speed is usually 13 to 90 kilometers per hour (eight to 55 miles per hour). If the winds become stronger than that, the controller turns the turbine off.
