Nordex has chosen the direct drive route, for maximum reliability. The company therefore takes the opposite view to that of Vestas, which has opted for a geared drive for the same reason. The Nordex view is that failures in a direct-drive system's electrical components may happen more often but that repairing heavyweight mechanical components causes more lost days overall, especially in the case of a gearbox breakdown which most often involves bringing out a jack-up vessel.
'Our point of view is that with the direct-drive you have mechanically fewer components, which means fewer components to fail,' says Thomas Karst, chief executive of the newly-formed Nordex Offshore GmbH. 'If you look at the statistics, the gearbox still represents a large proportion of the problems that arise.'
'Out at sea in particular, we must do everything we can to optimise the technical reliability of the turbine. With cost structures differing to those in the onshore market, we are able to implement a more complex drive system, namely a direct drive,' says Thomas Richterich. To partner the direct drive train Nordex has opted for a permanent magnet generator coupled with a full power converter, the whole designed to harness wind speeds of around 10 m/s, and substantially lighter than formerly used. Nordex is engineering this drive design in conjunction with experienced suppliers and is therefore placing its reliance in proven technology.
Nordex has not yet settled on any maker for the PMG for the new machine, but says it is currently working with various suppliers to deliver the entire generator-converter system as it further develops the turbine design. Only system suppliers able to deliver the entire generator/converter system and who are already market leaders in this area, says Nordex, are being considered.
Phanta-semper wird aber langsam Zeit auf einen Riesenauftrag von 500-1000 MW für heute, wird langweilig hier................du alter basher++++++++hahahahahahahahahahaha da lachen ja die Hühner
........... CEO AEDB, Mr. Arif Alauddin narrating the steps required for development of the wind power project, said that a lot of grid code was required to be changed for evacuation of power to national grid which was changed for the first time in the history Pakistan. He appreciated NEPRA for quick processing of FFC case in shortest possible time, and NORDEX for not only supplying turbines but also being EPC Contractor of the project. Only a few years ago, the wind energy sector of Pakistan had little attraction to the investors and suppliers. ..........
danke für die guten news der erneuten nordexaufträge von insgesammt 500-1000 MW++++++ haben schon dieses jahr 9000-10000 MW von dir gemeldeten Aufträge für Nordex...........ich danke dir für die guten Nordexaufträge, jetzt müsste es aber mal rauf gehen auf 19,5 €......................du alter basher (((((PHANTASMOGoRIA alias SEMPER AUGUSTUS))))) hahahahahahahahahahahahahahahaha .
..leider wird nun wieder alles vollgespamt...schade semper und auch thesame..habt ihr das wirklich nötig.
fakt ist das vestas gerade verprügelt wird und sich bei nordex erst zeigt wohin der weitere weg geht.
von den gemeldeten aufträgen sieht es nunmal bei nordex besser aus im moment. auch die personaldecke gestaltet sich günstiger und nordex hat schon letztes jahr mit einem kostenoptimierungsprogramm angefangen ( soll nach aussage richterrich 15% bringen)....bei vestas wird gerade erst damit gestartet.
habe mich geirrt sind doch schon 10000-15000 MW die du für dieses Jahr gemeldet hast für Nordex, damit wäre Nordex für die kommenden 5-7 Jahre zu 100% ausgelastet, nicht schlecht...............du alter basher (((((morgoria-semper))))) aufgepasst Semper ,denn die MODS lesen mit......................hohohohohohohohoho .
