Danke. Der Einfluss der Blätter ist bei der Anlage tatsächlich erheblich. Grund hierfür ist die kurze Distanz zwischen Blatt und dem Thies 2D Ultrasonic und die Hinterkantensegmente, die dort am größten sind.
Great video, thanks. Can you explain the magnetic field strength difference between DD, and geared units and safety distances for each please. Many thanks, good sir.
Unfortunately, I am not so deep in the service topics, but as far as I know, an oil sample is taken annually and examined in the laboratory. If the oil quality is then poor, it is replaced. Often the composition or quantity of additives no longer fits or there are metallic or non-metallic impurities. The oil change itself is carried out either manually with pumping into canisters or with a special pump truck. The amount of oil depends on the type of gearbox and is usually between 150 and 900 liters. I hope this answer helps you :-)
Hey, how are you doing? I've come for more knwoledge :D. I have a question, are there any wind turbines connected to 110kV? Is the high voltage already present in the hub, i.e. is the transformer in the hub? Im talking about the todays big turbines 150 metre rotor and up. Thank you very much.
Hey Mike, no Problem :-) 110 kV is unsuitable for Turbines in many ways (higher savety distances -> bigger Nacelle, much higher costs for Trafo and control, more weight, no 110 kV Trafos in this Power range) so there are absolutely no Turbines with that Voltage. But, what is commonly done instead is the connection of several Turbines (mostly 20kV) to a nearby Transformer station (110kV), starting at approximately 30MW of capacity. The Generator on most Turbines is producing Energy at 690V, which then is fed to a Transformer ( in the Nacelle, Tower Bottom or Trafo Station outside) and converted to mostly 20kV (10 to 36kV also possible). Whereas older Turbines had their Transformer always in the Bottom, the Trend goes clearly to Nacelle Transformers, due to some cost-advantages. Vestas or Gamesa is doing it since 20 Years. If you look at big new Turbines you came across Nordex Delta 4000, GE Cypress, Enercon E-Nacelle. I can also upload some Pics, just tell me what you are interested in. Servus 😉
@@saasch_baasch thank you very much! I’m in search of a suitable site, it’s really challenging to find a place that checks all the needed criteria and when it all looks promising the locals are against it haha. So for example the 35kV high voltage goes all the way up into the nacelle right? For example in a Vestas turbine.Thanks again.
there are plans that took 7 Years for just one Turbine. In that time, the original planned Turbine is heavily outdated. Welcome to Germany 😑. The high Voltage is going through a special Cable (~100mm Diameter) directly into the Nacelle.
@@saasch_baasch oh well, try setting up a wind turbine in Czechia like me 😅. Impossible. Another person I know has a project he is working on for 12 years, he invested hundreds of thousands into grid connections and wind measuring. Environmental projects. He got a green light from locals but some lady in Büro won’t allow soil to be converted from farm land. So now he is really thinking about ditching the idea but the money will never be returned.
Ja, das kommt immer auf die durchschnittliche Partikeldichte in der Luft an. In Deutschland hält sich das on Grenzen, da gibt es besondere Peaks bei der Getreideernte und anderen trockenen Feldbearbeitungen.
Does anyone know what regulations are there / what requirements have to be met for a windturbine to have avaition lights - red / white strobes installed? i thought every turbines has a strobe light installed but to my surprise I saw two E-40 without any lights on top and just 3km away three E-53 equiped with red lights. This got me wondering if theres any law, rule or requirement for turbines to have strobe lights installed or is it just a additional option which can be chosen by the owner when built.
Depends highly on your country and local regulations. In Germany every new Turbine must have red 50cd aviation lights for night. Following a new regulation they may be turned off if there is no plane near, so called "adequate control" with radar or internet based detection of planes with transponders. In special places (near airports, military flight zones, etc.) There may be also a day strobe 20.000cd mandatory. If or what is mandatory is mainly defined by the German aviation agency and the military aviation agency. On older Turbines there may be also just red paintings instead of aviation lights due to missing regulations or lower heights of the Turbines. There may be also an exception for Turbines inside a huge windfarm which is surrounded by Turbines with aviation lights. Hope this fits your question.
so unlike a water turbine the generatot is not directly coupeld to the grid so watt kind of conveter is able to coverte the variable frecrenty output of the genarator to the fixed 50hz of the grid or do i miss somting
There is a technique of feeding ac to the field windings which allows the output frequency to be controlled independently of the generator input shaft speed.
Sehe einfach nicht richtig, oder lief die leicht gedrosselt?🧐Hat das die Anlage von selber gemacht, um den Betrieb zu optimieren, weil die Fernüberwachung kann es ja nicht sein. Der Wartungschalter is ja aktiv.
Gedrosselt war die nicht, aber ich glaube das lag einfach daran, dass nicht genügend Wind war, bzw. der Wind recht böhig war und die WEA da "herumgeregelt" hat.
When they made the controller I don’t think they had an idea that thousands of people would be gazing at it through their cellphone and computer screens 🙃 It’s also in the nacelle far above the ground so the physical audience is quite limited and it’s probably hot as hell in there the summer, so simplicity and robustness is a must. (As an aside in the winter it’s probably quite annoying since LCDs don’t like the cold. I’d also assume this is just for a quick reference and more in depth information can be had via some form of PC communications.)
@mysock351C I realize all that. I've spent 45 years in the power industry working on everything from 130 year-old hydroelectric plants to solar and wind. It's just the contrast of massive slate panels with intricate clock like electromechanical relays and meters with a 2" LCD screen. I'm an old man!
@ The old victorian era stuff is a bit misleading by today’s standards as much of that was built as part of various vanity projects to showcase the progress of technology and the heralding of a new era. It’s photogenic because it’s meant to be. Same with industrial steam engines of that era. Absolute works of art. In an ideal world it would be great if stuff was still made like that as it has a character and life of its own. But sometimes the motives behind it were often arguably as self-serving as modern green energy. Problem with these is the blades and gear trains in them only last about 20 years or so as they are out in the elements. The blades will erode and the bearings and gears will pit out. After that it gets dumped in some pristine forest out of sight. I’d almost be more angry if they put a big fancy TFT in there. It’s just gonna get scrapped. That’s the problem with free energy: It’s located in remote, inhospitable places for technology. It doesn’t live inside a nice, large reactor hall or industrial facility. All this stuff has a short lifespan, so we should at least appreciate it doesn’t have some no name controller from BigDongBang Electronics Co. in Shenzhen China.
@ Now the flip side of what you bring up was the old grain supply in town that became a hardware store. _Its_ electrical system was more typical of what I might expect. The electrical board was literally a board with fuse holders and ancient breakers screwed to it. All the wiring was bare #12 AWG copper on vitreous insulators, even running down to the light switches! Made it interesting to go in as a kid. Dare was always to reach up and touch them. They were live at 120V and you’d get a wallop out of them. In the late 80’s the township finally made them replace it all if my memory serves me correct. They decided that the potential for electrocutions and three alarm fires outweighed its significance as a historical landmark. No more zaps, sadly.
@@andyfeimsternfei8408The electromechanical equivalent is analogous. Those types are not only obsolete, but potentially the “cheap” versions anyway. But I’d like to see a mechanical system do a fast Fourier transform.
Another great video. I'v no enercon experience but I feel ready for some troubleshooting now 🛠️😋 you have good wind speeds. How long does it take to do test ?Id try to stay away from generator windings when turbine in full power. Was there a fault on turbine ? I wonder did you fix 🤠😋
Thanks :-) The test before start takes several minutes and is dependent on Windspeed. I also keep a distance to the Generator and HSS during testruns, but on these types of Turbines it's different. The magnetic field strengths are also acceptable in this distance. On this Turbine we just did a regular inspection😊
Yes these are direct drive so safer to work in. Which is your favourite type of turbine to work in ? Do you travel for your job much ? You go offshore ?
I travel a lot, I mean a lot like "I don't travel in my vacations since 8 Years despite I am easily able to" 😄 I was offered several times to go offshore, but I declined until now. Every Turbine do have its own advantages and disadvantages when it's about servicing and of cause direct driven Turbines do have less parts so they might be easier to service, but this isn't the case for several reasons 😄 all modern Turbines are easier to service due to much more space and more ergonomics. Personally I like the Vensys Turbines very much, their whole machine design is unique and well engineered, with great serviceability as well 😉
So 18 RPM is about 1.88 rad/s
2.3 MW / 1.88 rad/s = 1.22 MNm or about 124.5 tonnes-meter
Holy crap!
3:55 that’s no a generator…. That’s the weapon of the Death Star starting up😂
Sehr schön von dir auch mal wieder was zu sehen. Krass wie man an Windrichtung und Geschwindigkeit sieht, wann ein Blatt vor dem Messgerät steht.

Hello, nice machine, for me enercon is the best, for simplest mechanical drive.....
More expensive but I hope more reliables....
Good job 👍
Very interesting
Always interesting!
Thanks for a new video!!! 🤗

Fantastisch
Frage doch mal einen Betreiber in deiner Nähe, ob du bei einer Betreiberbegehung mal dabei sein darfst. Wenn du Glück hast klappt das 😏
How often is the oil changed in the gearbox of geared turbines like Vestas…? How much oil is it?
Unfortunately, I am not so deep in the service topics, but as far as I know, an oil sample is taken annually and examined in the laboratory. If the oil quality is then poor, it is replaced.

Use a small curent to control the genarator output

You would think a 2MW+ turbine would have something more than a cheap LCD display!
