Wind turbines are typically designed to slow down or shut off completely when wind speeds exceed a certain threshold, usually around 25-55 mph, to prevent damage. This is often determined by the turbine manufacturer based on the turbine's design and capacity to withstand high winds.

What is Runaway Speed of hydraulic Turbine and how it is calculated?
The runaway speed of a hydraulic turbine is the maximum speed at which the turbine can rotate without the aid of any load or braking system. It is calculated based on the turbine's design characteristics, such as the operating head and specific speed, and can be estimated using empirical formulas or through simulation software. Exceeding the runaway speed can lead to mechanical damage or failure of the turbine.
What is speed ratio of turbines?
The speed ratio of turbines refers to the ratio of the rotational speed of the turbine rotor to the rotational speed of the turbine shaft. This ratio is important for defining the mechanical performance and efficiency of the turbine.
What does the turbine blade do to the speed of the wind?
nothing wind turbines make the energy
What does a turbine blade do to the speed of wind?
A turbine blade slows down the speed of wind as it passes through, converting the kinetic energy of the wind into rotational energy to drive the turbine. The amount of speed reduction depends on the design and size of the turbine blade.
Stall control wind turbine?
Stall control in wind turbines involves adjusting the angle of the turbine blades to maintain optimal performance. When wind speeds increase, the blades are pitched to "stall" or reduce their lift, preventing damage and providing a safeguard in high winds. This control method helps to regulate the turbine's speed and prevent potential overload.

What is idle speed of turbine?
warm up speed of turbine,andthe minimum speed of turbine before loading is called idle speed.
Which device controls the speed of the turbine shaft?
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
What is speed ratio of turbines?
The speed ratio of turbines refers to the ratio of the rotational speed of the turbine rotor to the rotational speed of the turbine shaft. This ratio is important for defining the mechanical performance and efficiency of the turbine.
What is critical speed of turbine?
SPEED OF TURBINE IS DEPEND ON THE WATER PRESSUR(7BAR)
Why is the runaway speed of a hydraulic turbine always kept twice its normal speed?
The runaway speed of a hydraulic turbine is the speed at which the turbine coupled to the generator runs at the maximum possible speed due to loss of load and this happens until the shut off valves completely closes the discharge from the penstock. the runaway speed of the turbine is determined by the turbine designer and is influenced by the maximum discharge of water from the penstock, the combined inertia of the turbine runner and the generator and the flywheel. this factor can vary from 1.5 up to 3 times the nominal speed of the turbine and is determined by the turbine designer considering all the load parameters.
What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor

Generator is moving 3000 RPM on 320Mw powerif full load rejected and any protection is not activate generator work as a motor what are damage possible?
depends on many things, including the type of prime mover (what is powering generator?). Presuming a steam turbine (or possibly combustion turbine though that's large for a single CT-gen) at that size and speed. "Rejection" of load is a term often misused. I'll presume correct use in this case, meaning that the generator remains connected to the grid, but for some reason has stopped producing power. If on the other hand what was meant was the generator was disconnected from the grid, it will not "motor". Upon rejection of load with no change in prime mover, the turbine would increase speed to a point where turbine over-speed protection would trip the prime mover to the turbine (fuel or steam), perhaps depending on design there may be some pre-emergency turbine controls to help reduce or control speed to below the trip point (perhaps about 110%, again depending on design). but if there is no controls that operate (including on turbine) turbine-generator unit may speed to point of damage (even destruction) as the centrifugal force of the higher speed exceeds design characteristics of the unit. Back to original question... If the generator rejected load due to loss of its field current, or either an open or short circuit in the generator, it likely will not motor. However, if the generator remains wholly intact and connected to the grid (meaning the reason for rejecting load is the loss or reduction of the prime mover to the driving turbine), the generator will motor. Possible generator damage could occur due to heating or pole piece shifting, depending on how sudden the change of phase angle (power flow) occurred. More likely, is (steam) turbine damage caused by overheating, most often starting with the lower pressure area blading. It is not uncommon to "motor" hydro electric generators operating either as a pump, or as a synchronous condenser for voltage or VAR control. But hydro-turbine-generators operate much slower RPM, with larger mass and damage is not incurred.
Where is the turbine shaft speed sensor on a 1996 Ford Ranger?
This engine has no turbine or turbo. Although the 1996 Ford Ranger does not have a turbine or turbo, it does have a turbine shaft speed (TSS) sensor. It is located inside the automatic transmission.
