Jucker說(shuō)：“風(fēng)力發(fā)電項(xiàng)目采用ABB各個(gè)部門(mén)的產(chǎn)品和系統(tǒng)，甚至機(jī)器人技術(shù)也得到了應(yīng)用，機(jī)器人用于噴涂大型風(fēng)力機(jī)的葉輪葉片，

迅速發(fā)展
Jucker表示在過(guò)去兩年內(nèi)風(fēng)力發(fā)電部門(mén)發(fā)展迅速，這對(duì)ABB來(lái)說(shuō)是一個(gè)重要的契機(jī)，這將帶來(lái)更大的項(xiàng)目，鞏固ABB的行業(yè)地位。
他表示：“公共政策對(duì)潔凈能資源要求非常高，但是這項(xiàng)技術(shù)也是非常先進(jìn)的，現(xiàn)在每千瓦小時(shí)的發(fā)電成本比20世紀(jì)80年代降低了80％?！?

歐洲占世界風(fēng)力發(fā)電市場(chǎng)的69％，引領(lǐng)世界前沿，但需要繼續(xù)滿足歐盟到2020年20％的可再生能源目標(biāo)。
12％的解決方案
歐盟可再生能源政策官員Beatriz Yordi Aguirre在研討會(huì)上表示風(fēng)力發(fā)電目前滿足歐洲3％的電力需求，但是未來(lái)可以為歐洲提供12％的電力需求，其中1/3的電力是來(lái)自海上風(fēng)力發(fā)電項(xiàng)目。
她表示，歐盟投資用于可再生能源項(xiàng)目的23億五千萬(wàn)美元中12億美元用于風(fēng)力發(fā)電，并補(bǔ)充道，在歐洲投資銀行和其他銀行還將投資相當(dāng)大的一部分資金到可再生能源項(xiàng)目。

[COLOR=#708090]ABB Captures the power of wind
2007-05-14 - Wind, water and sunlight not only make a delightful afternoon, but are clean sources of renewable power generation and sustainable growth. ABB is finding reliable, cost-effective ways to harness the power that is locked in nature.
ABB recently hosted a seminar for wind energy customers in Milan, Italy to explore ways of using today‘s technology to reliably generate emission-free power.
"The Wind Power seminar is a perfect opportunity to present ABB‘s vast offerings to the wind power industry, and to give ABB´s perspective looking ahead," said Claus Madsen, the man in charge of ABB‘s Wind Power Segment.
Opening a morning customer session was the head of ABB‘s Power Products division, Bernhard Jucker.
Wind-generated power projects use products and systems from every ABB division, Jucker said. Even robotics plays a role - ABB paint robots are being used to spray the giant windmill rotor blades.
ABB is in fact one of the world‘s largest independent suppliers of internal components, controls and grid connections for wind generated power projects. Since the 1980‘s, the company has delivered more than 15,000 wind turbine generators.
The product mix for wind turbines includes generators, converters, transformers, switchgear, low voltage products, motors and cables. For wind parks, ABB offers systems studies, substations, grid connections, control systems like MicroSCADA, underground and underwater transmission systems like HVDC Light, plus service and maintenance plans.
Tremendous growth
Jucker said the sector has undergone tremendous growth in the last two years and represents a major opportunity for ABB, as bigger projects appear and the industry consolidates.
"There is high demand driven by public policy mandating cleaner energy sources," he said. "But the technology has also advanced; generation costs per kilowatt hour （KWh） are now 80 percent lower than they were in the 1980s."
There is tremendous interest in wind power projects using the latest technology to create reliable power that is immune to the wild price fluctuations of fossil fuels.
Europe leads the way with 69 percent of global installed wind generation capacity. But that will have to increase to meet the European Union‘s 20 percent renewable energy target in the European energy mix by 2020.
The 12 percent solution
EU renewable energy policy officer, Beatriz Yordi Aguirre, told the meeting that wind power is meeting three percent of Europe‘s energy needs right now, but could potentially deliver 12 percent, and that one-third of that could come from offshore wind projects.
Of the $2.35 billion earmarked for renewable energy projects by the EU, $1.2 billion will go to wind power, she said. There is also significant funding for renewable energy programs available through the European Investment Bank and elsewhere, she added.
A variety of renewable energy solutions from ABB were outlined in a series of short presentations.
High Voltage Direct Current （HVDC） research manager, Gunnar Asplund, explored the HVDC solution to the problem of transporting power generated far from the consumers who will actually use it, which is one of the challenges of offshore wind generation installations.
"Long distance HVDC transmission systems are ABB‘s specialty," Asplund said, including cost-efficient （and invisible） underground transmission solutions like HVDC Light.
Power transmission specialist, Lars Stendius, offered ABB solutions like to import and integrate wind-generated power into the grid, and to increase power transmission capacity.
Move offshore, double capacity
Most of Europe‘s installed wind generation capacity is currently land based. "If it were better placed offshore, you could satisfy double the consumption - six percent - with what is currently installed," he said.
Other presentations explored ABB innovations in generators and power converters, meeting grid code compliance requirements, and creating communications networks in wind installations. Afternoon sessions focused on specific ABB wind power components and systems, including machines and motors, drives, transformers, power electronics, controls, breakers and switches, substations, compact substations and grid systems.
Meanwhile, at the EWEC product fair in Milan ABB presented wind energy products like the new ACS800 liquid cooled wind turbine drive converter. This compact, enclosed unit is ideal for offshore installations. It features stable operation in harsh environments and advanced technology that reduces power current distortions that can arise from wind generation, delivering cleaner power from the turbine to the grid.
Also on display from ABB Medium Voltage is the new 36 kilovolt （kV） SF6 gas-insulated compact switchgear, designed to protect the turbine‘s internal network. ABB in Norway has just signed an order with Vestas, the market leader in wind turbine applications, to supply switchgear to a wind project in Spain.
The switchgear design comprises modular cubicles to permit free access through the wind tower door, which is essential. It can be dismounted inside the tower, and the modular cubicles replaced, as they are smaller than the width of the tower door.
For Vestas, ABB developed a special solution to satisfy a customer request for minimal site intervention: the switchgear was mounted in the factory with special mechanical features to strengthen the busbar and modular connection, and was fully pretested, mechanically and electrically.[/COLOR]
