2007-05-14――风,水和阳光不仅带来令人愉快的午后,也是可再生发电和可持续发展的洁净能源,ABB找到了一种可靠而经济的发电方法,这种方法蕴藏在自然界中。 最近,ABB在米兰,意大利为风能客户举行了一场研讨会,寻找一种运用当今的科技生产无排放污染的电力。 “风力发电研讨会是展现ABB的在风力发电行业多种方案产品,以及ABB展望未来美好前景的良好契机,” ABB风力发电部门经理Claus Madsen表示。 ABB电力产品部门总裁Bernhard Jucker拉开了早晨客户研讨会的帷幕。 [align=center] (左)ABB研发经理Gunnar Asplund,探究远距离电力传输――风力发电设备的一项挑战。(右)ABB风力发电部门经理Claus Madsen拉开客户研讨会帷幕[/align] Jucker说:“风力发电项目采用ABB各个部门的产品和系统,甚至机器人技术也得到了应用,机器人用于喷涂大型风力机的叶轮叶片, 实质上,ABB是全球最大的风力发电项目内部元件,控制和电网连接独立供应商,自20世纪80年代以来,该公司已经运送了15000多台风力涡轮发电机。 [align=center] (左)客户仔细观看ABB的ACS800液体冷却风轮机变频器。(右)ABB在EWEC风力发电技术贸易展会上[/align] 风力机的产品组合包括发电机,转炉,变压器,开关柜,低压产品,马达和电缆。ABB为风电场提供系统研究,变电站,电网连接,控制系统(如MicroSCADA),地下传输系统和水下传输系统(如轻型直流输电),以及服务计划和维修计划。 迅速发展 Jucker表示在过去两年内风力发电部门发展迅速,这对ABB来说是一个重要的契机,这将带来更大的项目,巩固ABB的行业地位。 他表示:“公共政策对洁净能资源要求非常高,但是这项技术也是非常先进的,现在每千瓦小时的发电成本比20世纪80年代降低了80%。” 风力发电项目中有无穷的乐趣,运用最近的技术生产可靠的电力,避免用价格猛涨的石化燃料发电。 欧洲占世界风力发电市场的69%,引领世界前沿,但需要继续满足欧盟到2020年20%的可再生能源目标。 12%的解决方案 欧盟可再生能源政策官员Beatriz Yordi Aguirre在研讨会上表示风力发电目前满足欧洲3%的电力需求,但是未来可以为欧洲提供12%的电力需求,其中1/3的电力是来自海上风力发电项目。 她表示,欧盟投资用于可再生能源项目的23亿五千万美元中12亿美元用于风力发电,并补充道,在欧洲投资银行和其他银行还将投资相当大的一部分资金到可再生能源项目。 在一个简短的陈述中还展出了ABB的多种可再生能源方案。 [align=center] 展会上:(左)领先的涡轮制造商Vestas表示,风力或许是免费的,但是运用风力发电却需要大量技术和资本投资。(右)剖面图向客户展示了巨大风轮机内部的工作状况.[/align] 高压直流(HVDC)研发部经理Gunnar Asplund探究了向实际使用电力的消费者远距离传输电力的HVDC解决方案,这个方案将是海上风力发电安装的挑战之一。 Asplund说:“远距离高压直流传输系统是ABB的专长,包括经济的(隐性)地下传输方案,如(如轻型直流输电)。 电力传输专家Lars Stendius为ABB提供了各种方案,如将风力发电运用到电网,以及提高电力传输能力。 远离海岸,双倍容量 目前欧洲的大部分风力发电厂都在陆地,如果在海上,则发电能量会提高一倍,即6%。他说。 展出的ABB的发电机和整流器产品系列的其他创新产品满足电网规程要求,并为风能安装装配通信网络。下午的会议集中关注ABB特殊的风力发电元件和系统,包括机械,马达,变压器,电力电子,控制器,断路器,开关设备,变电站,紧凑型变电站以及电网系统。 同时,在米兰召开的EWEC产品展会上,ABB展出了风能产品,如新型ACS800液体冷却风轮机变频器。这个紧凑密封的组件是海上风力发电厂的最佳选择,具有恶劣环境中稳定运行的特性,技术先进,降低动力电流畸变,风力发电可以产生动力电流畸变,风轮机为电网传输洁净电能。 展出的ABB的中压产品是新型的36kV SF6紧凑型空气绝缘开关柜,设计用于保护涡轮内部网络。ABB挪威公司不久前与Vestas,风轮机应用的市场领袖,签署了一份合同,为其西班牙的风力发电项目提供开关柜。 开关柜设计包括模块柜,以使自由进入风塔门,这是基本的设计要求,因为开关柜比风塔的门小,开关柜也可安装在风塔内部,去掉模块柜。 Vestas开发了一个特殊方案,满足客户最小现场干涉的要求:开关柜安装到有特殊机械特性的工厂中,以加强母线和模块间的连接,开关柜经过完全机械和电子预期测试。 original text: [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]
