Wind Energy Essay

The parts are high speed generator, three stage gearbox, rotor and three blades. The top of the tower has the gearbox is fitted. The two sides of gearbox are one side is blade and other end has generator. The direction of wind flow has turned nacelle setup by the yaw drive system. The wind velocity energy, brake system and hydraulic unit are controlled by the electronic control unit. The yaw drive system is placed in that the vertically downward to the energy base plate. The rotor blades are energy two or more in number and are made of Glass-fibre reinforced plastic or Epoxy resin laminated wood. It also includes structures wind Aluminum Copper for lightning protection and steel for the connection to wind hub. The hub in turn transfers the energy to the low speed shaft. Blade designs operate on either the principle of drag or lift. Essay the drag design, the wind pushes the blades out of the way.

Essay blades can be rotated by using either drag force or lift force. Drag powered wind turbines are characterized by slower rotational speeds and high energy capabilities. Blades come in many shapes and sizes, and there essay continuing research into which design of wind is best.

It turns out that the optimal design really depends on the application, or where and how the blade will be used. This is the ratio between the speed of the wind and the speed the blade tip. Fiberglass rotor blades represent the most vulnerable components of a wind turbine. Lightning, Vibrations or contact with the tower can result in major damage to the blades.

Design errors and manufacturing defects can also cause problems in the rotor blades during its operation time. For example, blades energy develop cracks at the edges, near the hub or at the tips. The possibility of the bolts breaking due to overload also cannot be ruled out. Brakes are used to stop the rotation of rotor shaft in case of power overload or system failure. The High speed shaft is equipped with an emergency mechanical disc brake, which is used in case of failure of the aerodynamic brake, wind when the turbine essay being serviced.

The low energy shaft of the wind turbine connects the rotor hub to energy gearbox. The low speed shaft wind at relatively slow speed of energy 19 to 40 revolutions per minute and transfers the rotational energy from the hub to the gear box. The essay contains pipes for the hydraulics system to enable the aerodynamic brakes to operate. The power transmission system increases the speed and transfers the rotation energy to the high speed shaft, which rotates about 50 times faster than the low-speed shaft. The generator converts the rotating motion of gear box shaft into electricity at medium voltage hundreds essay volts by the principle of Electro magnetism.

Inside this component, coils of wire are rotated in a magnetic field to produce electricity. The most commonly used generator in wind essay are induction generators or asynchronous generators. Modern wind turbine generators are installed on tubular towers large turbines uses tubular tower. The tower thickness is 12mm plate. It has made energy of cast iron high grade material.

A wind turbine works the opposite of a fan. Instead wind using electricity to make essay, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Wind turbines, like windmills, are usually mounted on a tower to capture the most energy. Wind turbines operate on a simple principle.

The energy in the essay turns two or three propeller-like blades around a rotor. Energy rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are essay on a tower to capture the most energy. At feet 30 meters or more above ground, they can energy advantage of faster and less turbulent wind. A blade acts much like an airplane wing.
