Wind Turbine shuts down in Storm

This is the Repower MM92, rated power: 2000kW, rotor diameter: 92.5m, hub height: 100m. These turbines usually shut down at about 25 m/s or 55 mph, this is the maximum operational limit The time span in the video is about 2 hours while the wind speed went up from about 18 m/s to 30 m/s. When the wind was gusting up to 30 m/s the rotor blades were pitched out of the wind.

Why don't they spin it away parallel to the wind direction?

On a pitch controlled wind turbine the turbine's electronic controller checks the power output of the turbine several times per second. When the power output becomes too high, it sends an order to the blade pitch mechanism which immediately pitches (turns) the rotor blades slightly out of the wind. Conversely, the blades are turned back into the wind whenever the wind drops again.

The rotor blades thus have to be able to turn around their longitudinal axis (to pitch)

At last someone that knows how the industry works. Prices will drop once money starts flowing in.

@johnairlines8 It shows. No, they do not shut them down if there 'is enough power', they shut them down when there is too much wind.

ANd i would report the fact your wind turbine is going that fast. they arent supposed to. it could mean the brakes in the turbine have failed, in which case i would be looking for a new home.

@titytit The wind turbine in my town spins all the time. Going fast enough to explode. They shut them down if there is enough power. Quit asking other people for their oppinions on Wind Turbines and research it. You do realise your fighting with an 12 year old ;)

@johnairlines8 you do know that most of the time, wind turbines arent actually spinning?

They shut them down if the wind speed is faster than a heavy breeze......

god forbide, a storm comes through.....

wind power is a waste of time. If we develop nuclear power far enough, we could have reactors that run for hundreds, if not thousands of years, only needing tiny amounts of fuel to continually produce massive amounts of power.

DOnt be stupid and beliee the media and AGW alarmists.

@TJDeadkid oh and 4) use fusion, whose waste, depending on the fusion process, can be water and/or helium and/or Ozone, msot of which can be cracked easily in a fission reactor (for even more power) and reused as many times as you want.

@titytit And wind never stops blowing ;) don't be stupid

[titytit]

@TJDeadkid there are plenty of ways to deal with waste:

1) Use Fission waste in a hybrid reactor or Fusion reactor (both of which could be used to eradicate 99% of the radiation).

2) Use the radiation-absorbing fungus found at Chernobyl to absorb the radiation.

3) Use Thorium, whose waste has very little, if any radiation and the radiatio it does have dissipates in a few years (as it isnt radioactive naturally, we need to prime it, which means very little to no radiation to worry about).

@johnairlines8 and? it was still one of the largest earthquakes in the last 40 years to hit japan. my point is still valid.

[johnairlines8]

@titytit It was a 9.0 Dumbass. 9.5 was in Chile. Before you say another stupid word you need to research and go fuck your stupid hillbilly white trash ass

[TJDeadkid]

@titytit where are they putting all the waste?

[titytit]

@johnairlines8 interesting fact: 12 large fusion reactors could power the WHOLE EASTERN SEABOARD OF THE USA.

Japan has over 140 million people, and only 2-3 dozen fission reactors. How many wind farms do you think Japan would need to supply the same amount of power they get from 36 nuclear reactors?
