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.
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 😉
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.
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.
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 :-)
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.
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.
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.
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.
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!
Fantastisch
Frage doch mal einen Betreiber in deiner Nähe, ob du bei einer Betreiberbegehung mal dabei sein darfst. Wenn du Glück hast klappt das 😏
Great video, thanks.

Always interesting!

Very interesting
Die maschine sieht echt sehr sauber aus. Hier in Spanien sammelt sich eine menge staub auf allen flechen.

Geil ey
15 m/s ist schon gefährlich da oben aber geiles Video.
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. Often the composition or quantity of additives no longer fits or there are metallic or non-metallic impurities.

just don't press the AZ5 button!
i love seeing the wind turbine control consoles.
