世界風(fēng)電發(fā)展趨勢

國際上目前最大的風(fēng)電葉片是多大的？有沒有人關(guān)注呢。

重量偏差超過設(shè)計重量的1%。

就應(yīng)該坐下來想想究竟出了什么問題了。

對于5800公斤的葉片，有700公斤的偏差，那就是重大問題了。

國內(nèi)很多企業(yè)的葉片超重很多呢
.......

[s:8]這個問題應(yīng)該好多廠家都存在的，幾乎都有超重的，配重的時候就把重的配一堆了，銘牌上重量照樣不變，哈哈

laney

四舍五入嘛！ [s:2]  [s:2]  [s:2]
重量：17740kg（LM資料顯示：該數(shù)據(jù)只是preliminary data）
做出來超重也正常的

國內(nèi)很多企業(yè)的葉片超重很多呢
比如：設(shè)計重量5800kg，實際有6.5T左右，這個~這個~就不好說了~ [s:7]

laney錯了，是61.5m，17.7T,哈哈，我是專門挑刺兒的

10MW的有存在的可能性否？

6M瓦的出來了。由Enercon，Repower出的。Repower用的是LM的葉片，仍然是61.5米長，Enercon用自己做的葉片，葉片很有特色。

REpower assembles 6-MW offshore turbine

REpower Systems AG (Hamburg, Germany) announced on Dec. 19 that it has completed the assembly of the first three REpower 6M turbines in Bremerhaven. The wind turbines, which each have a rated output of 6 MW, are expected to be erected at the Westre civic wind farm on the German-Danish border. There, they will undergo a comprehensive testing program and checks for certification according to the DIBT classification.

The new offshore wind turbine technology is based on the successful 5M range. Since the dimensions correspond exactly to those of the REpower 5M, the REpower 6M can later be used in all the projects planned for this turbine type. In future, series production will take place in the wind energy company’s new assembly hall in Bremerhaven, which is designed to produce and directly ship more than 80 nacelles and hubs per year. The hall tests for the three 6M turbines were recently completed there successfully. At the beginning of 2009, the turbines are to be erected at the Westre civic wind farm, owned by Grenzstrom Vindtved GmbH & Co. KG, in which 200 limited partners from the communities of Westre, Ellhöft and the Danish town of Lydersholm have holdings.  

Speaking about the progress of the project, the REpower CEO Per Hornung Pedersen, said, “With the first installation of the REpower 6M, which is due to take place shortly, we are once again proving our leading technological position in the field of multi-megawatt turbines. We expect that the Offshore division will continue to grow in importance and that the future of wind energy in Europe will be found to a large extent on the open seas.”  

At the beginning of next year, REpower is also expected to sign a framework agreement with RWE Innogy GmbH, which has already been announced. Pedersen said: “The negotiations are already very advanced and we are confident that we will soon be able to conclude the contract for 250 offshore wind turbines of the 5M and 6M types.”
