The wind industry presents specific challenges when dealing with tool operator injuries. Because of remote locations and hazardous working conditions, it can often take hours for help to arrive once an injury occurs. Safety needs to be considered in every aspect of the job. Hand Injuries: costly in many ways Hand injuries, in particular, can be not only devastating to a worker, but also costly to a project budget. Worker compensation claims for hand injuries average around $7,500 per injury. The Bureau of Labor Statistics cites that approximately 110,000 hand injuries result in lost time. Hand injuries send more than 1,000,000 workers to the emergency room each year. The construction industry requires the tightening of approximately 30,000 bolts per year, so if not done properly, the chance for hand and finger injuries is significant. In the construction industry alone, the annual cost of hand cuts and punctures is around $400 million. When dealing with wind tower construction and maintenance specifically, these injuries most often include bruises, cuts, abrasions, punctures, fractures, and even amputations.

对于太阳能行业来说,2020年将是值得铭记的一年。在实现2019年的强劲扩张后,由于新冠疫情的持续蔓延,太阳能行业在2020年出现了一些不确定因素。 若干趋势会一直延续到2020年及2020年以后,其中之一便是业界对基于LED的模拟器能够满足其计量需求越来越有信心。LED闪光器在2019年轰动一时,许多公司都对这项技术充满信心,许多项目的生产线末端安装了基于LED的模拟器。WAVELABS是一家总部位于德国萨克森州的制造企业,主要生产Sinus-220 LED IV型电池测试器等产品。据该公司报告,与2018年相比,其销售额增长了7倍。 LED太阳光模拟器在近几年才被市场广泛接受。此前,自工业太阳能电池制造伊始,脉冲(AC)和连续(DC)氙灯便一直是效率测定的标准光源。由于固态照明技术的突破式发展,基于LED的光源已被证明是一种更好的测量方法。主要原因在于LED能够将各种颜色结合在一起,从而更加准确、可靠地匹配太阳光谱。本文旨在揭示氙灯模拟器和LED模拟器的优缺点,以及在选择模拟器光源时需要考虑的因素。另外,本文还将阐述一些表明基于LED的技术在太阳能计量领域具有强劲趋势的其他因素。 氙光的优缺点 氙灯最突出的缺点是其与标准光谱之间存在较大偏差(如图1所示),这主要是由波长大于750nm(纳米)的氙光波峰造成的。氙光谱的偏差远远超出A级设备的允许公差,从而导致了效率测定的不准确。

链式碱抛系统,作为SCHMID集团的一个重要研发成果,通过利用碱溶液(KOH)替代较难处理的硝酸(HNO3)来进行刻蚀,获得优异的边缘隔离和抛光效果,是目前市场上唯一无需使用硝酸的链式刻蚀设备。 目前行业常用酸刻蚀工艺对硅片进行边缘隔离和抛光,根据不同工艺要求,利用氢氟酸和硝酸(HF/HNO3)混合药液对硅片进行腐蚀,腐蚀深度为2-7µm。在整个工艺过程中,硝酸将硅氧化成二氧化硅(SiO2),同时产生大量的氮氧化物气体(NOx)。根据相关的环境法规,这些废气必须经过净化处理。HF/HNO3酸刻蚀工艺不仅化学品成本更高,而且废液、废气处理成本也很大。因此,SCHMID研发并采用KOH溶液来进行刻蚀,大大降低了化学品耗量和成本以及相应的处理成本。同时,这也更加满足日益严格的环境要求。 基于40多年丰富的湿法工艺经验,链式碱抛系统结合了SCHMID量产多年的链式碱单晶制绒机台和其他久经验证的湿法设备的优点,将多个工艺步骤集成到一个模块化的设备中。一方面将扩散工序生成的背面发射极与前表面发射极隔离;另一方面去除硅片表面的磷硅玻璃(PSG)。

撰稿人:Shuli Goodman,LF Energy 执行董事 近年来,随着智能设备、新硬件以及支持通信和数据交换的软件解决方案的推出,能源网发生了巨大变化。虽然该等变化标志着可再生能源被广泛采用这一积极趋势,但公用事业公司仍在努力分析和提高电网效率。 尽管设备互联性和产生能源的新方法均在增加,但由于流程过时,运营商仍不得不制定非标准解决方案来应对挑战。对于不同的供应商控制系统和设备,标准的实施情况通常有所不同,并且,访问电网数据需要几种不同的设备,而每个设备都可能涉及不同的流程。 此外,我们过去一直采用的是单一方向供电,以防止运营商小范围控制负载。当供需不匹配时,这会导致效率下降。随着电池、太阳能电池板、风力涡轮机和无线解决方案等更多设备的出现,供需关系变得更加不可预测。当前基础设施不仅限制了能源相关的信息通信,还限制了跨电网自动多向智能的创建。往后,这种复杂性只会有增无减,而我们将需要使用人工智能和自动化来促成微秒间隔的交易,以保持安全和平衡。 若无法通过双向电网提取有关能源使用情况的电网数据,公用事业公司就无法对变化作出实时响应。随着天气依赖型可再生能源的需求不断增加,我们需要找到一种电网数据访问和分配方式来更精确地响应能源需求。Grid eXchange Fabric (GXF) 是一个工业物联网 (IoT) 平台,最初由荷兰能源运营商 Alliander 作为“开放式智能电网协议”推出,其后于 2 月初归入 LF Energy。该平台实现了通信并消除了基线障碍 ,使得电网运营商可以安全地监控和访问数据。

The CompositeLoop project is a feasibility study that proposes short term solutions in Flanders, Belgium for the valorisation of large thermoset end-of-life GFRP (glass fiber reinforced plastics) structures such as wind turbine blades, boats and yachts, profiles, silos. The study is based on literature review and input captured during three interactive workshops with stakeholders over the entire decommissioning to waste valorisation value chain. It identifies promising local short-term scenario’s, with the purpose of initiating synergies within the value chain, allowing further technical and commercial development of recycling solutions as a next phase. 1 Large GFRP structures with fast-growing waste volumes Wind energy is the strongest renewable energy source currently in Europe and it will only increase because to reach the EU goals of 32% renewable energy by 2030, significant increase in wind power capacity is required. Wind turbines are being built since 1980s and boomed around 90s and 00s. They have 20-25 years of lifetime. Thinking about the development in wind energy in the last 40 years, it is understandable that every year more wind turbines are reaching their end of life. In 2018 alone, total of 421MW of wind power was decommissioned where 14MW was from offshore wind plants1.

WindEurope Offshore 2019 is where the journey begins. Taking place on 26th to 28th November, the Copenhagen event will gather the entire offshore wind industry as it prepares to scale up to meet the Paris Agreement. PES brings you a comprehensive preview to this key event. Offshore wind is set to play a major role in the world’s energy mix, according to a new report from the International Energy Agency (IEA). In its ‘Offshore Wind Outlook 2019’, the IEA predicts that global offshore capacity may rise 15-fold by 2040. In the wake of this announcement by the IEA, Europe’s largest offshore wind conference and exhibition will take place in Copenhagen’s Bella Center. WindEurope Offshore 2019 will attract more than 9,000 visitors and playing host to over 400 exhibitors. With offshore wind staking a claim to ever more of the globe’s energy mix, the decision to host this event in Copenhagen was easy. Unlocking the full potential of European offshore wind will require vision and commitment, and Denmark is setting an ambitious example for other countries to follow. Across Europe, Denmark has the highest share of wind energy in its electricity demand – 41% last year – and is home to many of

The UK power cut that occurred on Friday 9th August at 4.54pm affected many across the country. At first, speculation that followed the events suggested the fault could have been due to wind generation reducing owing to reduced wind speed. In fact, the issue was the amount of generation that tripped, not the technologies involved. Just before the teatime peak, the Little Barford gas generator tripped whilst exporting about 660MW. Two minutes later, the Hornsea offshore wind farm tripped, removing another 800MW or so from the supply side. The combined loss of around 1,440MW dropped the grid frequency to 48.8Hz, which was measured by one of our Energy Routers stationed at a customer site. This level of frequency is well below the statutory limits imposed on National Grid. The generation loss was above the level that National Grid plans for in a largest single loss, which is currently 1200MW from Sizewell B. Early information suggests the outages were entirely coincidental and unrelated issues. At very low frequency levels, there is automatic load disconnection to protect the system and help to restore frequency to normal levels. The system was operating normally at a grid level within around 15 minutes. Had the
