Testrun and Tour through Windturbine GE 3.6MW 137m at high Windspeeds

Here we have a nice member of the 3MW Plattform from GE.
Diameter: 137m
Power: 3600 kW
Hubheight: 131m
Windspeed at Testrun: 10-13m/s

[@Max_Jaeger]

Very nice. If we just simplify for a second, that the turbine is operating at it's peak power from 2:30 until "Turbine Stop" is pressed at 5:40 we'll get 3 minutes and 10 seconds of "full" operation. Seems very little right? But during that short amount of time it generated approx. 190kWh, that's enough to power a normal 4 person household (≈9kWh/day) for 21 days or allows you to travel 1055km (643,6mi) in an normally sized electric car (18kWh/100km , 295Wh/mi). And all of that just by harnessing the power of the wind for a measly 190 seconds, ain't that beautiful? Best electric regards, Max Jäger

Soooooooo Cooool . Die GE 3.6 steht bei mir in der Nähe 3 Mal.

[@SalvoZ06]

Excuse my ignorance .... but do they need a button to start? Don't they move with the force of the wind?

[@saasch_baasch]

Don't hesitate 😄. The start button is not comparable to the ones in a car or a rocket. The start here is comparable to the following situation: you are standing with your bike up on a hill, brakes pulled.... then as you push the start button you release the Brake and start to accelerate down the hill, without any kick. (Just an analogy...) What really happens there is that the Blades can turn (pitch). Before you press start the Blades are in a feathering position, which means that there are no forces to turn the Rotor. As you push start the Blades pitch in so that there is a resulting wind-force that accelerate the Turbine without any useage of the Generator, that gets pulled just like the whole drive train. After reaching a certain rpm the inverter is kicking in, resulting in a Torque in the Generator which is directed against the direction of the acceleration of the Rotor. This "braking" energy (comparable to the recuperation in an electric vehicle) is then fed into the Grid. As I said, as you push start, the only thing that is pulling power out of the Grid is the pitch drive that turns the Blades... which then in combination with enough wind results in an acceleration of the whole Rotor and Drivetrain. 😊

[@CoolAsFreya]

Wow what a sound! Interesting that you can activate the turbine from up top, I assume hearing protection is required!!

Great video, some running commentary on all of the equipment and parts would have been useful, even if it it was added after being shot.

[@baraemanuel8469]

What are rpm of generator working ?

[@NUENG_4.1_27]

4:34 is 2048

[@NUENG_4.1_27]

4:34 00:04:34

[@UCCLdIk6R5ECGtaGm7oqO-TQ]

So I guess these are a variable frequency system (inverter?) or do they sync to grid? I was expecting to hear it cut-in at some point but didn't hear anything notable.

[@saasch_baasch]

This type of Turbine has a partial Power Converter in the Bottom of the Tower. Also the Powerswitch is at the bottom, so the only Thing you hear at Grid connection is a smooth screech from the Generator. Most modern Turbines have full /direct power Converters, which are allowing the Turbine to have a wide band of rotational speed and adapt to every Windspeed with a maximum efficiency.

[@zebgraves4562]

The high pitch ringing at 3:26 is when it’s connecting to the grid, you’ll feel the tower “load down” as it increases the torque on the generator. There’s a series of IGBTs separated by a DC link that simulates a variable frequency on the rotor side of the generator but always produces at grid frequency on the stator side.

[@eventhorizon7374]

No brake is applied on forced stop, only blade feather?

[@familieanderson2292]

I’d love to work on one of these one day

[@dpranjko]

I work on them and we are always looking for people 😅

[@ruanjiayang]

If we install some intelligent cameras (with AI algorithms embedded) to monitor and inspect the turbines, which location/locations is/are your best suggested one? considering the pretty limited space within the nacelle. What are the most critical things to monitor?

[@saasch_baasch]

Uh, what a difficult question. First of all, there are already various systems that monitor the condition of the plant continuously and cost-efficiently. If you use cameras, you often need very high-resolution sensors with high contrast, for example for ice detection (position best at the back of the nacelle). One problem here is the contamination of the lens (but there are solutions for this). It is just as difficult inside, because you would have to look inside the gearbox or generator. Many parameters cannot be read out with a camera sensor. There is an interesting technology called motion amplification, which amplifies the movement of subpixels and can thus detect tiny movements. But so far this is not possible on the wind turbine, because everything is really moving and you don't have a still reference. AI is successfully used, for example, for bird detection (position at the base of the tower, viewing direction above). As long as a camera does not outperform an existing system in reliability, accuracy and cost-effectiveness, it is unlikely to happen. One must always remember that energy must be produced as cheaply as possible.

[@ruanjiayang]

@@saasch_baasch Yes I understand, that is why I aim to R&D camera solutions that more or less minimizes man-hour climbing towers. Furthermore, do you think in-nacelle sound/voice collectors (detect abnormal noises of gearbox or generators, converters) are usable?

[@saasch_baasch]

Acoustic and acceleration sensors (CMS Systems) are widely used in Turbines. Due to their low costs and reliability, some Turbines do have dozens of them.

[@martsevoy]

I heard GE combine the most specific features of the Vestas and Enercon concepts. As far as I can see from this nacelle, it's true.

[@saasch_baasch]

Yes, that is at least partly true. GE uses an electric pitch similar to Enercon (or Nordex and many others) and a gearbox drive train, as do many other manufacturers. But the biggest difference to all the others is that GE uses partial converters for the onshore turbines, while all the others have full converters.

[@martsevoy]

@@saasch_baasch At the same time, both the converter and the transformer are located at the bottom, which is also part of the Enercon philosophy.

[@martsevoy]

@@saasch_baasch partial converters? does this mean that generator is doubly fed induction generator? like Siemens Gamesa?

[@MrCharizardTCG]

@@martsevoyyes

[@Socalfishingkids]

They put the oil cooler on the bottom of the 3x or is it gone?

[@saasch_baasch]

The oil cooler is located at the very rear of the nacelle and is force-ventilated.

[@nicholadstoap6944]

So when u press stop the blades are feathered?

[@saasch_baasch]

Exactly 😊

[@GavinFreedomLover]

I shared your channel on my channel hopefully you get some more subs, peace!!!

[@zefrimohd2619]

How many turns for the generator equivalent to one turn of the outside blade?

[@saasch_baasch]

I don't know the exact ratio, but is must be between 100 and 120 Generator rpm per Rotor rpm. This is why they use a huge planetary gear as first and second Gearbox stage. The Torque on the Generator at rated Power is 23000 Nm, on the Rotor shaft approximately 2,8 MNm

[@mattlovelace91]

Isn’t it 1:90-91ish? That’s the ratio from low speed to high speed shaft at least.

[@heliosex7238]

wonder what would happen if you hit emergency stop

[@Sven745]

There is a brake disc on the high speed shaft. When you press emergency button, the brake is applied. Turbine swings like hell and that's it. Been there done that, but from the bottom.

[@Cherrylinh1710]

you give me document ?

[@lebronaldo]

Ich fordere eine GE 4.2-137, die den E138 EP3 E2 und V136 4.2 Aufträge abnimmt

[@martsevoy]

is there an electric pitch?

[@saasch_baasch]

Yes, the Pitch is regulated by an electric motor, attached to a very high ratio gearbox, which then turns the whole blade via a gearing on the blade bearing. I will upload a video soon wher you can see the different types of pitch

[@steventaylor6294]

What is that secondary shaft for?

[@saasch_baasch]

You mean the smaller one between Gearbox and Generator? This is the feed through shaft, and the thing you see on the end of it is the slip ring. This setup serves the purpose of delivering electric or in some cases also hydraulic energy to the Hub. This shaft can be find on all Gearbox Turbines and is naturally always located at the center and along the Rotor axis.

[@steventaylor6294]

@@saasch_baasch yes, the slow turning one. Looks like it synchronises loading profile

delta 4k wird schwer. NX hat sich da etwas pingelig, du darfst nur gewisse anlagenteile zeigen. Mache momentan Wartung auf 9x Delta 3600. Ist tatsächlich vom sehen und vom hören her weniger los als auf einer Gamma.

@@ThePerle1997 da hast du recht, die ist zumindest Subjektiv ein Stück leiser. Die transparente Kupplungsverkleidung und gesamte Ergonomie und Begehungsfreundlichkeit finde ich sehr gelungen, besonders im Vergleich zur Gamma. Aber die Belüftung der D4000 mit dem kleinen Lüfter über der Kranluke ist recht dürftig. Mit der "Hochspannungsheizung" neben dem Geno ist der Aufenthalt im Maschinenhaus in den warmen Monaten fast unerträglich. Da müsste man dringend für mehr Luftbewegung sorgen 😉 LG
