What is the differeance between upwind and downwind turbines?
An Upwind turbine faces into the wind with the turbine blades in front of the Nacelle* while a Downwind turbine has blades to the rear of the Nacelle and faces away from the wind. Up-wind turbines are by far and away the most common, but down-wind turbines (usually two-bladed) are also used in certain situations.In very strong winds the turbine blades of a wind turbine generator flex under enormous forces. With a down-wind turbine the blades flex AWAY from the mast which prevents them from crashing into it. Up-wind turbines need to be designed so that the blades are positioned at a good distance from the mast, and they must also be engineered to be inflexible (which costs more money). In addition, when the blades of a down-wind turbine bend it reduces the stresses on the mast as wind energy is lost in bending the blades. Finally, down-wind turbines do not need a tail (or motorised yaw mechanism) to align them with wind as the turbine blades perform this task (although this can also be a serious disadvantage in large down-wind turbines if wires carrying huge currents are getting twisted).Down-wind turbines on the other hand are generally noisier (additional aerodynamic noise), and the blades are subject to more forces than those of up-wind turbines. Another serious disadvantage of a down-wind turbine is wind shadow behind the mast causing a drop in power each time a blade passed behind the mast.*Nacelle = is located at the top of the mast and contains the rotor and generator, and sometimes a gearbox. Basically it is everything except the turbine blades, tail, and mast.
What is turbine rated speed and What is maximum speed rise of steam turbine?
Turbine rated speed varies mainaly on the factors of Generating frequency and means of coupling to generator (viz trough a gear box or directly coupled and no.poles in generator). For exmple a 50hz generting frequency and a bi-pole genarator the turbine speed is 3000RPM. The allowed speed rise also depends on turbine design and generator operational range. Generaly the speed rise is restricted to Maximum of 10% of the rated speed.
What are the two types of brakes on a wind turbine?
The controller and mechanical brakes.
What is a turbine barring gear?
When a large turbine rotor stops it will still be hot and will tend to bend in the middle if left to cool normally. To prevent this the barring gear will turn the rotor slightly at given intervals during the cool down period.
Do yaw bearings teeth point outward or indward on a wind turbine?
yes
How does a wind turbine operate?
The Wind Turbine Generator (WTG) is broadly divided into three parts. • Tower • Nacelle • Rotor The tower of wind turbine generator supports the nacelle and the rotor. The nacelle contains the key components of the wind turbine, including the gear box, the electrical generator, control panels etc. The rotor blades convert the kinetic energy of the wind to electrical energy through gear box and generator. The hub of the rotor is attached to the gear box. The gear box has a low speed shaft for its input. The high-speed shaft of gear box rotates at approximately 1500 revolutions per minute (RPM) to drive the electrical generator system. The heart of the wind turbine is its controller, which is responsible for the operation of the whole turbine. The embedded software in the controller monitors the various inputs and other condition and controls/actuates the outputs accordingly.
How do you calculate rpm of a wind turbine?
You can calculate the rotation speed (rpm) of a wind turbine by dividing the rotational speed of the generator (usually given in revolutions per minute, or rpm) by the gear ratio of the turbine. The gear ratio is the ratio of the number of teeth on the turbine's gear to the number of teeth on the generator's gear. This formula allows you to determine the turbine's rpm based on the generator's rpm and the gear ratio.
What are the five parts of the wind turbine?
Tower, blades, nacelle (casing around the inside parts of the turbine), hub (the front of the nacelle/looks like the centre of the blades), gear box transmission (not needed or included in all wind turbines), generator (to turn the electricty from kinetic to electrical).
How is electric city produced by wind?
due to the flow of wind, the wind turbine rotates, which will be coupled to the shaft of the alternator(generator) through gear mechanism
How is wind energy utilised?
wind turbines are placed to make use of wind energy, in the wind turbine an alternator having large gear mechanism is fixed , when the wind blows, the turbine moves, which in turn forces the gears to rotate, which in turn moves the alternator to generate electricity.
Do wind turbines have to face the wind?
Yes, wind turbines are designed to face the wind in order to capture the maximum amount of energy. This orientation allows the blades to rotate and generate electricity efficiently. It also helps to ensure the structural stability and longevity of the turbine.
What does a wind turbine make?
A wind turbine makes wind for scientific study.
What does wind turbine help?
a wind turbine generates electricity for or use
What does Wind Turbine mean?
A wind turbine is like a giant fan that produces energy from the wind
What analogy is used to describe the gear system of a wind turbine?
A common analogy used to describe the gear system of a wind turbine is comparing it to the gears on a bicycle. Just like the gears on a bike help adjust the speed and efficiency of pedaling, the gear system in a wind turbine helps optimize the speed of the rotor blades based on wind conditions to generate more electricity efficiently.
How is wind created in a wind turbine?
wind is not created by the turbine but wind that passes through the turbine causes it to turn, and the faster the turbine spins the more energy is created that can be turned into electricity and other resources. Hope This Helps :)
What is another name for a wind tower?
Another name for a windmill is the wind turbine
