I always wanted to be in the top when it starts/stops! Thanks for making this very informative video. The sound was just amazing on that machine!
Book your seat on "virgin wind power"... where u can...sponge of money...
Omg this is channel is absolute gold! Love it.
very well made, i sure miss those days! nothing like running the machine uptower.
That is MUSIC!!!! This is the best start-up sound I've ever heard of a wind turbine spinning up. Great video: thanks for posting.
i know im asking randomly but does any of you know of a way to get back into an instagram account??
I was stupid forgot the login password. I would appreciate any tips you can offer me!
@Gerardo Ephraim I really appreciate your reply. I found the site thru google and im trying it out atm.
Seems to take quite some time so I will get back to you later with my results.
@Gerardo Ephraim it worked and I now got access to my account again. I'm so happy:D
Thank you so much, you saved my account!
@Julian Brayan happy to help =)
That's some nice power from a little bit of wind. :)
Mega interessant. Krass wie stark das Maschinenhaus bei Volllast schwankt.
Ja, ich schau mal ob ich das demnächst mal bei einer Vestas 112 aufnehmen kann, da ist das am noch extremer 😁
@@saasch_baasch Please do! :)
Please more video its so interesting
Impressive 😍 we love how it sounds
Excellent video thanks!
Does the nacelle have any brakes or is it slightly free to move? Because at 2:15 I dont know if thats the nacelle moving/rotating or just the the tower bending.
Soo cool! There's some power there isn't there!
is the pitch controlled hydraulically here? or Servo? how is power transferred to the Servos? are there any slipping rings and carbons?
Hey, the Pitch is driven by two hydraulic zylinders for each Blade. The Oilpressure is transferred from a Hydraulic Station inside the Nacelle through a slipring to a central distributor inside the Hub, which then controls each zylinder.
The flex and twisting those towers undergo from the torque force of the blades is crazy. Do you ever get a thought like "what if this tower just snaps on me rn" when you're up there? Isn't it the main reason for replacing old blades and turbines in whole because the fiberglass become brittle over time and could suffer catastrophic failure by breaking off in high winds? Just curious because I'm still contemplating about whether to go down the path as a wind technician or not. Thanks for the video!
Nice thoughts man, I will tell you a story first 😄
I was a lot younger and absolutely fearless about my job (which doesn't mean I wasn't aware of possible dangers). We were in the Bottom of a Turbine (Nordex N117 Gamma on a 100m steel Tower) and my colleague started the Turbine. Normally the Blades are pitching in, rpm is rising and then you hear the Sound of the main Generator switch, followed by the constant high frequency noise of the Converter. On this day however it was different.
So the Turbine was gaining RPM and I was walking out of the door as the main switch closes and suddenly I heard the sound of the Converter for a short period of time, but this time extremely loud. I dont know the exact details, but to put it simply: a software bug caused a total shortcut of the generator, so the generator stopped from full speed, also stopping the whole drive train, Blades included. This outburst of energy gets absorbed by the machine frame and is then guided through the Tower.
What I saw was an almost instand stop of the Turbine (way faster then an emergency Stop) and literally a wave traveling down the Tower, bending the whole 1500 ton structure like a straw of grass in the wind. I thought this is the end🙈 I started to run away. It was, if not, the most wicked experience of my life.
My colleague however was Inside the Tower, looking at the control and didn't even notice something, just that the Turbine is in alarm state. I was running for my life and he was having a little tea in there😄
The Turbine survived well and had some damage to the coupling between generator and gearbox.
Now to your question: the Blades are actually quite flexible and made to withstand the forces over time. Most catastrophic failures are due to poor manufacturing of similar faulty installations and high power lighting strikes when the lightning protection system has a problem (happens occasionally). A good Blade will last a whole 20+ years normally.
The Tower and the connection of the sections is under the heavy influence of fatigue. An average Tower and Blade is been stressed by 150-200 million perods of bending in 20 Years, which may lead to fatigue cracks in those components. This is one of the main Parts of my job, detect those Cracks and other things, that could endanger the structural stability.
But despite a whole bunch of deadly or heavy dangers on a Windturbine, this job is one of the safer jobs in the industry, according to statistics. The Rule is simple, stick to the savety measures and keep your eyes open to unexpected hazards and you will be very save.
If you want to do a job in the wind industry, I can highly recommend, it's a nice working environment if you are a little adventurous want to see new places and meet a lot of different people.
@@saasch_baasch Omg gnarly story for sure, glad you both stayed safe!! Thanks for sharing! I probably would've needed a little break from running those turbines if that was me who experienced such a thing😅sure hope they got that bug fixed. Thanks for that info. I find what you do very interesting and find myself binge watching your videos at night sometimes😂keep up the good work!!
great video thanks
Some of the shaking in the video seems to be in tune with 1/3 of the rotor speed. Is this because of an interaction between the tower and the blades?
Nice question! The Vibrations of the Tower due to a bypassing Blade is especially at newer Turbines not noticeable by Humans, but with a vibration long term FFT transformation it is measurable. This effect is extremely reduced by a tilt of both, Rotorblades and shaft angle, which lead to a high distance between the Blades and Tower.
The effect you see in the Video is caused by the following effect: the Camera is downwind behind the Rotor, so it is facing the same "linear flow - turbulent flow - linear flow" at each bypassing Blade. Especially at high winds, these changes apply a highly impulsive force to all Objects inside this Stream and near to the Blade. This causes a light shift of the Lens inside the Cam, which is controlled by an electromagnet. The induced Movement of the Camera is faster than the inertia of this Focus mechanism of my Cam, at each Blade passing by, which causes this shaking, despite the anti shake is activated. To be seen extremely in my Clip with the E40 at full Power.
@@saasch_baasch Thanks for such detailed answer!
I've heard this referred to as 'tower shock'.
Small turbine. I'm not sure I like the clamshell design, it means you get soaking wet from the rain when you need to work on it.
well, but in the Summer it is like Holiday ;)
This was very cool!
Just shows how much movement there is in these turbines? What sort of weight would the nacelle be with the blades?
The Nacelle weights about 82 Tons, the Rotor (hub and Blades) about 62 Tons. The Tower is 100m high and has approximately 200 Tons. If you are interested in a record weight, then take a look into Enercon E126 7.6M Specs: "The weight of the foundation of the turbine tower is about 2,500 t, the tower itself 2,800 t, the machine housing 128 t, the generator 220 t, the rotor (including the blade) 364 t. The total weight is 6,012 tonnes exactly." 😊
The Movement itself depends strongly on the type an height of the Tower and on Windspeed and Gust. The most Movement appears on most Turbine when you stop them. By far the most extreme Movement I experienced in an early Vestas V112 with the 120m Steel Tower, where the Nacelle can reach an Amplitude of more than 2 Meters, so more then 4 Meters overall Movement. You have to hold yourself well then 😁
@@saasch_baasch The tower is 2800t? Whaaat? Heavier than the foundation?
@@82NeXus actually true, because the Tower is made completely out of ferroconcrete, and not as usual Steel or Hybrid (approximately half ferroconcrete, half Steel).
Stupid question but how can rpm increase after grid connection? Doesn't it have to keep 50 hz on the generator?
Good question😄 your Assumption is totally right for directly grid connected Turbines. Newer ones do have a partial or full converter. The last ones do have a rectifier, followed by an inverter for the whole Power. So the Rotor RPM is decoupled to the Grid frequency and can maintain optimum adaption to the Wind situation.
@@saasch_baasch oh that is interesting. I'm guessing it takes a small efficiency penalty but now you can adapt faster to both power changes and work in a more effecient regime for the turbine it self. Thanks
What are the two sensors (in the central part of image) used for ?
These are aviation lights. There are always two of them at a certain distance apart so that an aircraft can see at least one at each rotor position.
@@saasch_baasch I thought they are anemometers
The anemometer and wind vane are at the very back on a kind of spoiler or mast. But you are not so wrong with your assumption, there are ultrasonic anemometers that look almost exactly like this, except that they are smaller 😉
Thanks for sharing this very useful video, but i have a question is that why before grid connection the power is negative, is it because we give the power from inverter to the rotating electrical machine in order to control the wind turbine with the MPPT ?
Hi Hamza, I answered this question earlier. This Turbine is not able to take power from the Converter into the Generator, this isn't even necessary for all Windturbines. Shortly before Grid connection the acceleration potential with the Power of Wind is huge.
This negative Power (shortly before Grid connection) is coming from the Precharching of the Converter to connect Smoothly with maximum control of RPM and other variables.
@@saasch_baasch Thanks for answering, the generator is it Permanent Magnet or Doubly Fed Induction Generator ?
Proof me wrong, but It's a short circuit asynchronous Type with full Converter.
I think wind turbines need to go bigger, much bigger if possible. Vestas has recently announced a 15MW offshore turbine. But what about 150MW!? D'you think it's possible?
There was some research done in USA a few years ago where they explored the idea of a 50MW turbine. It had the nacelle pointing into the wind so the wind blows on the other side of the blades and had blades that hinged away from the nacelle in high wind, following the wind like palm trees do (which can withstand hurricanes). That reduced the requirement for structural strength for the enormous blades.
I guess though the real question is how do you extract the most power from a given area of land? Do bigger turbines actually get you more power? Because presumably they're spaced wider apart?
Subbed :-)
The Trend goes clearly to higher, more powerful Turbines with larger Rotors. GE's 12 MW Haliade and Vestas 15 MW Turbines are already insanely powerful Turbines. Basically if you double the Diameter of the Blades you have 4 Times the yield (by squaring the Generator too). So if we take the Vestas MHI as Base with 15 MW and 235 m Diameter, then you need a Rotordiameter of approximately 750 m to feed a 150 MW Generator. In addition the Tower have to be about 400 m high. If this will be possible one day or if this will be more economic than a few smaller Turbines I really don't know. Maybe you ask "engineering with Rosie" here in YT, she has much more theoretical knowledge than me 😊.
The concept with the Blades behind the Tower (Lee-Turbine) and hinging Blades is interesting, but there will be also an Issue with the Tower and the insanely high bending Forces at a Hubheight of 400 m. Is there a Prototype? Please let me know.
If you wanna have more Power out of a certain piece of Land, than is is clearly evident that one big Turbine is better than a few smaller ones. This is due to the Fact that newer Turbines use areas in a greater height , similar to skyscrapers in a city. This is called Repowering, if you replace many Turbines with less bigger ones at the same Area and getting much more yield.
Yeah..it makes a lot of wind😁
is the negative power readout accurate? does it take 80KW to start a turbine? i've never really thought about it before, but it would make sense that you'd have to give something that big a small push start to get it going.
The negative Power readout is accurate indeed. The Rotor and the connected Drivetrain (Gearbox - Generaror) are accelerating only by the Lift that is produced from the Blades. The minor negative Power is coming mainly from the Lights in the whole Turbine, Control, Hydraulics and other auxiliary Systems. The sharp increase in negative Power at Grid Connection comes from the Precharching of the Converter and / or from the reactive Power compensation System. In other types of Turbines, there is also the excitation for the Generator, which also consumes higher Amounts of Energy. The overall Power (auxiliary consumption and Power Output) you call gross Power. The Power exported to the grid is net Power, which is then the rated Power, in this case 2300KW. By the Way, some Turbines are capable of producing more then 1MW over the Rated Power to intercept strong gusts at high winds😉
@@saasch_baasch wow really? What turbines can do that? Well also where I live we have reserved how much power can be delivered to grid so I suppose we would be charged for this?
@@Mike-kr5dn i have seen Vestas V80/90 with peak power of 3300kW for example. But this Power is just for very short periods of time. The Power reservation or Power Limitation is common, especially at newly build Turbines and lagging grid expansion or if the local Grid is on the Limit generally. This Power excursions are not charged as far as I know, due to there rarity and shortness.
@@saasch_baasch Thanks for the info. I suppose you work as a service technician. I know that there are different servicing schemes. What is the typical servicing you do? How often do you fill up grease containers?
@@Mike-kr5dn the Greasing intervals are mainly between 1/2 and 1 Jear. Depending on different schemes and intervals at different manufacturers, the Servicemen do greasing, torque control of Bolts, change Air and oil filters, cleanup in many different Areas, diagnostics of Bearings Alignments and Oil Quality, electrical Measurements, general repairs, change of worn parts, eg. Brake pads, and some more.
The schemes are called eg. Main Service, grease service, electrical service, 400h Service (after commissioning), 4 Jears Service, wind dependent Service and more, quite depending on manufacturer.
I am not working as a Service technician, so my tasks are different 😉
the rated power is 2300 KW, here we can see a second of 2309 KW and the wind speed reach to 9m/s, if the wind speed reach to more than 12m/s, the rated power will be increased to how much? is it works ok?
Nicely observed... this behavior is totally normal, the reason is simple: Wind is more or less gusty, these gusts may be pretty fast and strong. The reaction of the Turbine to this gusts is delayed due to its inertia. Some of the excess energy is spread by the bending of the Blades and a slightly increasing rpm. What's left then is discharged with short power boosts which are within the designed electrical and mechanical limits (a discharge in power resistors is also used in some Turbines). The maximum power Boost is varying a lot on different Turbines but is usually 3 to 10% of the rated Power. On one Turbine type it may reach up to 50% of the rated Power! (1MW Boost in extreme wind conditions)
@@saasch_baasch Thank you very much for your fast and detailed reply.

Schade, dass die ATS135m SWT92 nur einmal gebaut wurde in Grevenbroich
wooooow
Is that the motor kicking in feathering the blades out?
I don't know exactly what you mean, but the Pitch at this Turbine is done with Hydraulics, so the hydraulic power unit is starting to provide the Pressure for Pitching all Blades ti feathering position.
how much electricity this device consumes?
It generates electricity
@@felixbeutin8105 yes when it's windy but what about when it's not windy
@@jyynidepends on what systems are active. with the turbine completely off it will consume nothing. starting obviously takes energy
Engine jet
I sound of jet engine
What does "Power" mean?
Servus Bepi, mit Power ist Leistung gemeint. Vergleichbar mit der Motorleistung eines Autos. Da steht zum Beispiel 80kW (108 ps), die der Motor bei Vollgas und einer bestimmten Drehzahl leisten kann. Bei dieser Anlage sind es 2300 kW, die bei entsprechendem Wind in das Netz eingespeist werden. kW (Leistung) ist nicht zu verwechseln mit kWh (Energie/Arbeit).
LG, Seppi
@@saasch_baasch Das ist aber nicht die eingespeiste Leistung oder? Wofür braucht man dann die Angabe?
Ich weiß leider nicht ganz genau was du meinst. Also es gibt die Nennleistung (hier 2300kW), das ist die maximale Leistung, die die Anlage in das Netz einspeisen kann. Ist der Wind geringer, ist es natürlich weniger. Nennleistung und tatsächliche aktuelle Leistung sind beides wichtige Angaben, die sowohl bei der Planung als auch im Betrieb von zentraler Bedeutung sind.
@@saasch_baasch Naja ganz rechts steht ja "GEN" was vermutlich die generierte Leistung ist. Nennleistung sollte ja auch am Typenschild stehen.
Power = momentan an das Netz abgegebene Leistung
Winds = Windgeschwindigkeit in m/s
Geno = generatordrehzahl
:-)
bad design to need a diesel engine to get it started

Up is soo noisy bit far away is not noisy and the movement is scary
Especially the actual Turbines are looking very calm and slow turning, but from Inside it's always as crazy as in other kinds of powerful Machines.
