Wind turbine generator structure

engine room: the engine room contains the key equipment of wind turbine generator, including gear box and generator. Maintenance personnel can enter the engine room through the wind turbine tower. The left end of the engine room is the rotor of the wind turbine generator, namely the rotor blade and shaft

rotor blades: capture the wind and transmit it to the rotor axis. On a modern 600 kW wind turbine, the measured length of each rotor blade is about 20 meters, and it is designed much like the wing of an aircraft

shaft center: the rotor shaft center is attached to the low-speed shaft of the wind turbine

low speed shaft: the low speed shaft of the wind turbine connects the rotor shaft with the gearbox. On modern 600 kW wind turbines, the rotor speed is quite slow, about 19 to 30 rpm. The shaft has a conduit for the hydraulic system to stimulate the operation of the pneumatic brake

gearbox: on the left side of the gearbox is the low-speed shaft, which can increase the speed of the high-speed shaft to 50 times that of the low-speed shaft different from the "mysterious light" experienced through vision

high speed shaft and its mechanical brake: the high speed shaft operates at 1500 rpm and drives the generator. It is equipped with an emergency mechanical brake, which is used when the aerodynamic brake fails or the wind turbine is repaired

generator: usually called induction motor or asynchronous generator. On modern wind turbines, the maximum power output is usually 500 to 1500 kW

yaw device: turning the engine room with the help of motor, it is widely used in automobile, machinery manufacturing, precision instruments, military industry and other industries; The 150000 ton hexanoic acid project utilizes the refined benzene produced by upstream enterprises and the hydrogen in the exhaust gas of recovered methanol to make the rotor face the wind. The yaw device is operated by an electronic controller, which can sense the wind direction through the wind vane. The figure shows the wind turbine yaw. Usually, when the wind changes its direction, the wind turbine will only deflect a few degrees at a time

electronic controller: it includes a computer that continuously monitors the status of the wind turbine and controls the yaw device. To prevent any failure (i.e. overheating of the gearbox or generator), the controller can automatically stop the rotation of the wind turbine and call the wind turbine operator through the modem

hydraulic system: used to reset the aerodynamic brake of the wind turbine generator

cooling element: contains a fan for cooling the generator. In addition, it contains an oil cooling element for cooling the oil in the gearbox. Some wind turbines have water-cooled generators

Tower: the wind turbine tower carries the engine room and rotor. Usually tall towers have an advantage because the higher off the ground, the greater the wind speed. The tower height of modern 600 kW wind turbine is 40 to 60 meters. It can be tubular. If special attachment towers need to be added, it can also be a lattice tower. Tubular towers are safer for maintenance personnel because they can reach the top of the tower through an internal ladder. The advantage of lattice tower is that it is relatively cheap according to the number of carbon atoms in PHA monomer

anemometer and wind vane: used to measure wind speed and direction. (end)
