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

[@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

[@saasch_baasch]

Exactly 😊

[@musicnerd72]

​@@saasch_baasch Why does it slow down to a certain speed and "coast" for several minutes then slows further to a stop quickly after that?

[@saasch_baasch]

@musicnerd72 The power is reduced gently during this time so as not to overload the power grid. When the power is then at 0 and the generator main switch is open, the system stops quickly. This behavior takes the longest with this type of turbine, with others it happens quite quickly. However, if the turbine is stopped in an emergency stop, this happens just as quickly as with the others.

[@musicnerd72]

​@saasch_baasch Makes sense. Thanks for the explanation. Your videos are beyond fascinating to watch! 👍

[@CoolAsFreya]

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

[@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. 😊

[@musicnerd72]

​@@saasch_baasch Perfect explanation! Thank you. 👍

[@baraemanuel8469]

What are rpm of generator working ?

[@notloc3463]

Usually, there is about 800 rpm in the hub. The generator bumps it up to 1800 rpm 😊

[@Schinkeldink]

btw depending on if the grid is 50hz or 60hz. here in Europe with 50hz ideal rpm is 1800 while in the USA grid with 60hz it's more around 2200rpm

[@diehardmetalhead3797]

@Schinkeldinkdude sync rpm by design is 1500rpm. 1800 rpm is super synchronous , turbine controller and converter is able to pull energy from the rotor at super synchronous speeds if it is a DFIG of course. Most of the GE turbines can stay in sync down to 999rpm.

[@diehardmetalhead3797]

Generator is variable speed. There is a converter (imagine a wall adapter but it works both ways kinda) rotor spins at different speeds depending on the gear box ratio. But even tho generator is not at sync speeds turbine controller and converter is able to sync to the grid. So it doesn’t need to run at designed sync speed.

[@diehardmetalhead3797]

Sync rpm for the generator at 50Hz is 1500rpm, at 60Hz it is 1800rpm.

[@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.

[@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]

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.

[@Cfyufugfuyug]

I love this video!! Thank you

[@burningdust]

What I don’t understand is why wind power always seems to be more maintenance intensive as compared to hydro generation.

[@Therationalnationalist]

Hydro (concentrated, monolithic) vs wind (dispersed, granular). It is easier (up to a point) to build a really big machine to satisfy a large demand, than to use lots of smaller machines. Each unit will have a base level of maintenance required to function for a long period. Even though the hydro dam will have higher maintenance requirements than an individual wind turbine, the wind farm will likely have a higher base level than the hydro dam if it has enough wind turbines.

[@astromarkus123]

What's the ratio of the gearbox and the rotational speed of the generator at nominal power?

[@HuliMAKAflip808]

[@TheYyam85ahaz]

5:18 I wonder how many times guys service those things and leave the hatch open by accident, after returning to the ground 😂

[@ptonpc]

That rising note and when you looked outside. Eeek!

[@GavCritchley]

I'm interested in how these work. So once the blades get upto the 'right' rpm, it seems a clutch engages and the generator is brought online? And then there must be some switchgear that keeps the generator output at a steady wattage/voltage? Is all that handled by the gearbox or power converter? And then getting the power down the tower...this must sound stupid I know, but the cables are fixed at the top (or perhaps not, are they on a sliding pick up?). The wind will track around, the blades/turbine follows it....does the head then power back to start its track again...and let the fixed cables unwind?

[@stevelacker358]

No clutch. If the particular turbine uses a conventional alternator: then Once the alternator gets close to synchronous speed, the output is tied to the mains at the instant the alternator and mains are in phase, and that puts the load on the turbine and adds power to the grid. There are also turbines which use asynchronous alternators that can output mains frequency over a wide range of shaft RPM, which lessens the need for precise shaft speed control. AFAIK, power is sent down the tower through a set of slip-rings.

[@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.

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

[@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.
