The runaway speed of a water turbine is its speed at full flow, and no shaft load. The turbine will be designed to survive the mechanical forces of this speed. The manufacturer will supply the runaway speed rating.
wind pushes on the blades of the wind turbine which pass on this motion to the generator to produce electricity. The energy and the speed of a wind turbine depend on the blade pitch control which depends on the angel of the blade chord to the plane of rotation. The blade pitch determines the speed of the turbine which also depends on the wind speed. Energy is directly proportional to the speed of the turbine. Therefore, the energy produced by a turbine depends on both the wind speed and the blade pitch angle. By: Amin Elsersawi
They're as close as the build method will allow them to be. And they have to be pretty darn close, as any imbalance at something that big spinning at speed can cause serious vibrations which might actually damage the wind turbine.
usually an wind turbine consists of large gears at its shaft point which produces slow speed to high speed to run the generator coupled to it
There are a few things on the backs of Wind Turbines: 1) Anemometers - wind speed sensors that help the turbine fine tune its blade pitch to be most efficient. 2) Wind Vanes - wind direction sensors that keep the turbine lined up with the wind, or turn it away from the wind when the gusts are too strong and can damage the turbine. 3) Visibility Lighting - red and white lights to meet requirements of aviation authorities for visibility.
warm up speed of turbine,andthe minimum speed of turbine before loading is called idle speed.
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.

SPEED OF TURBINE IS DEPEND ON THE WATER PRESSUR(7BAR)
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind 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.
self sustaining speed is output of a turbine= input into compressor
Where is the turbine speed sensor on a 2001kia rio with automatic transmission
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.
yup you can completely total your car which sucks and you have to pay for any damage that may occur
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.
Critical speed means where natural frequency is equal to system frequency.
