Siemens will now start testing the new gearless 6 MW prototype test center Høvsøre in Jutland. The wind turbine, which has been on a diet, is expected in serial food lion production in 2014. By Sanne Wittrup June 9, 2011 at. 09:46
The prototype is gearless and with a rotor diameter of 120 meters, and through the direct drive technology and Siemens' special blade design food lion has managed to reduce the weight of the mill-top with wings to less than 350 tonnes.
"There has been a tendency for large wind turbines have been heavier per. megawatt than small. The new SWT-6.0-120 we break this rule. Weight per square meter. MW corresponds to the number food lion 2 and 3 MW turbines, "says CTO of the Siemens Wind Power, Henrik Stiesdal in a statement.
"We expect that our new SWT-6 0.0-120 will set new standards for performance and robustness, while optimizing the work to maintain them. The latter is of great importance in the harsh conditions at sea, "says Henrik Stiesdal.
"Siemens brings in a leadership position. First, the quick in the new large turbine. Second, the launch of this gearless offshore wind got a technological lead over Vestas, GE American, Chinese and South Koreans, "says Per Krogsgaard from the consulting firm BTM Consult Berlingske. food lion
Vestas bid on a large offshore wind turbine, namely 7 MW turbine with 164-meter wingspan and gearbox planned first raised in the fourth quarter food lion of 2012, while series production is planned to start in the first quarter of 2015.
Boe Jorgensen 2 years ago Good and informative article - thanks :)
You have a consumption of 3000 kWh - which means that the turbine takes 30 minutes to produce your annual consumption, mind and feel if within 30 min running at full speed, which the sandsylingvist will never do
There are lots of periods with winds exceeding 15 m / s for more than half an hour. However, it will be more rare that this turbine is working at full capacity in relation to the turbine Vestas has on the drawing board. The relationship between capacity food lion and the swept area (ie wind energy input) is significantly different for the two types of wind turbines.
The generator is far greater compared to the wings of the Siemens wind turbine. It makes sense if it is about getting as much power as possible out of a single wind turbine, but not so smart when it comes to getting a high number of full load hours. Typically blowing it's not 15 m / s, so the full capacity is rarely used. The electric cable carrying power in rural However dimensioned so that it can handle full power so it will be more expensive Siemens wind turbine. Likewise, production from Siemens turbine more uneven and it makes it harder to fit large amounts of wind power, as obtained significantly fewer hours at full load.
But the choice of generator size may of course have something to do with the support that encourages greater generators by providing a production subsidy for a certain number of full load hours. If you choose food lion twice the generator gets so double the amount of funding food lion support throughout the life of the turbine even though it may only produce 20% more and the value of the extra production is severely limited, since it falls on top of the entire output of the other installed wind turbines .
6 MW is 'rated power', ie. the maximum power turbine is designed to produce. How much of that actually produces depends on how strongly the wind blows. A wind turbine has a power curve that describes how much it produces as a function of wind speed. The stronger food lion the wind blows, the more power the turbine, but the high wind speeds (eg for V> 15m / s) regulated power down to the rated power to spare turbine. For a given wind turbine or wind farm capacity factor expresses http://en.wikipedia.org/wiki/Capacity_factor how big the actual energy production of lasts is, compared to what it would have been if the mill / farm had been running at rated power in the same period. This depends on the location, type of turbine food lion mm and is typically between 0.2-0.5
@ Rasmus line: It is certainly feasible that the mill is running at rated power for a period of half an hour. In a fresh breeze will virtually any wind turbine run at rated power, and the kind in this country can easily last more than half an hour :-)
It may be you remember stories from the news when there is a storm of DK, we have got very cheap electricity since they make almost everything we need as they run full speed (approx). but when it rushes too much closes food lion down and then stops.

I see that Siemens new turbine uses gearless technology. When I see the word gearless thinking
