海上風(fēng)電：葉片究竟會(huì)變多大？

Editor's Commentary

Additional coverage of composites in the wind energy market in this issue include: "Windpower 2009 Highlights"The American Wind Energy Assn.'s (Washington, D.C.) show confirmed wind energy’s status as a recession-proof market for composites, but blade manufacturers were put on notice about the need to automate. "Work in Progress: Automating wind blade manufacture"Recent technology announcements portend a new era of more efficient blade production. "Engineering insights: Challenged to engineer retrofit blades"Myriad interrelated design factors are considered in new blades for turbines originally built for high-wind regimes.


2008 was another banner year for the wind energy industry. Recent data suggest that global installation of new wind turbines last year exceeded 28,000 megawatts (MW) of rated capacity (roughly 19,000 turbines), worth approximately $48.9 billion USD (

估計(jì)碳纖維很快就要上場(chǎng)了。

尤其是在剛性驅(qū)動(dòng)的超大型葉片設(shè)計(jì)當(dāng)中

又Repower 制造，（現(xiàn)為SUZLON了）

PS：最近Repower接5MW風(fēng)機(jī)的單接了不少。看來(lái)經(jīng)過(guò)幾年的原型機(jī)運(yùn)營(yíng)，開(kāi)始獲得認(rèn)可了。

不同葉片設(shè)計(jì)及其質(zhì)量對(duì)比

LM的Super root technology 和Super blade technology 經(jīng)過(guò)幾年折騰，看來(lái)不是吹的。

碳纖維看來(lái)功不可沒(méi)。在50米以上的葉片當(dāng)中，碳纖維的部分使用和設(shè)計(jì)的改進(jìn)，可以帶來(lái)三分之一的質(zhì)量減輕！[s:7]


TPI 的創(chuàng)新概念葉片設(shè)計(jì)也是相當(dāng)?shù)睦兹恕＞尤话?0米的葉片重量拉到了10噸一下。

不知道我們什么時(shí)候能上50M 的，哎資金有限啊，市場(chǎng)有限啊！GE快點(diǎn)多接單子[s:1]

。。天哪。。。壯觀啊。。。。。。額額。。。

我看見(jiàn)2.5mw的機(jī)艙罩就覺(jué)得好大了，要是10mw的話是不是要一個(gè)車間那么大了啊。。。。長(zhǎng)見(jiàn)識(shí)了。。嘿嘿。。。

碳纖維沒(méi)那么容易用上的 [s:1] ，目前大部分碳纖維的原料聚丙烯晴纖維價(jià)格已經(jīng)是國(guó)內(nèi)的王牌玻璃纖維價(jià)格的幾倍了，而且碳纖維制造過(guò)程能耗特高，產(chǎn)品價(jià)格是玻璃纖維的十幾倍到二十幾倍，估計(jì)只有超大的葉片主要承載部分可以用，例如主梁，當(dāng)然碳玻混編更好了。 [s:1]
