In the five EU member states Belgium, Denmark, Germany, Great Britain and the Netherlands, 32 companies from all sectors of the business area of offshore wind energy were investigated. Companies from the fields of Planning and Development, Foundation Technology and Tower Construction, Mechanical Engineering and Plant Construction, Fibre Composite Technology, Electrical Engineering and Network Connection, Assembly and Logistics fields were represented, as were companies which focus on service, maintenance and repairs and maritime construction and consulting. Expert interviews with managers and employees directly on-site have increased the requirement for further training and qualifications in multinational groups as well as in small and medium size enterprises, so that all plant sizes are represented accordingly in the analysis.1 To begin with, this study presents a profile of the status of wind energy use in the five European partner states and shows the particular challenges presented by offshore wind energy use with regard to new technologies and the qualification of employees. An evaluation of the expert interviews shows a wide range of new qualification requirements, some of which are cross- sector and others sector-specific. New requirements with regard to employee qualifications in the areas of project management, national and international law, quality assurance, occupational safety and health care, technical English and English for negotiations as well as offshore training arise in almost all sectors of the value added chain. In addition, sector-specific qualification requirements have been demonstrated which concern the areas of engineering training, welding and fibre composite technology as well as additional mechatronic knowledge for assembly and service employees. Preferred types of further education were also enquired about, as was experience in cooperation with research institutes and competence centres. Finally, the detailed analysis of the transnational cooperation of companies in the whole European market also revealed deficits which can be attributed to a lack of comparability and transferability of national professional qualifications, certificates and standards and which repeatedly lead to cost-intensive friction in cross-border cooperation. Therefore, the creation of comparable European training and qualification standards would be one factor leading to an improvement in cooperation. 1 The Project EQUIB carried out in 2003 an investigation on qualification requirements with focus on onshore windenergy industry in Germany (Hammer, Gerlinde; Röhrig, Rolf: Qualifikationsbedarfe im Windenergiesektor, Bremen/Bremerhaven 02/2004) This study was supported by the cities Bremen, Bremerhaven, Cuxhaven, the district of Cuxhaven and the Windenergie-Agentur Bremerhaven/Bremen e.V. 22/09/2005 5 Qualification Requirement Analysis Offshore Wind Energy Industry Final Report A Qualification Requirement Analysis for Offshore Wind En- ergy Use: Aims and Methods of the Analysis Following the enormous growth of the wind energy sector in recent years, the area potential for onshore plants in many areas has been almost exhausted.

  • Wind Power: Energy of the Future It’S Worth Thinking About
    Wind power: energy of the future It’s worth thinking about. »Energy appears to me to be the first and unique virtue of man.« Wilhelm von Humboldt 2 3 »With methods from the past, there will be no future.« Dr. Bodo Wilkens Wind power on the increase »Environmental protection is an opportunity and not a burden we have to carry.« Helmut Sihler When will the oil run out? Even if experts cannot agree on an exact date, one thing is certain: the era of fossil fuels is coming to an end. In the long term we depend on renewable sources of energy. This is an irrefutable fact, which has culminated in a growing ecological awareness in industry as well as in politics: whereas renewable sources of energy accounted for 4.2 percent of the total consumption of electricity in 1996, the year 2006 registered a proportion of 12 per- cent. And by 2020 this is to be pushed up to 30 percent. The growth of recent years has largely been due to the use of wind power. The speed of technical development over the past 15 years has brought a 20-fold rise in efficiency and right now wind power is the most economical regenerat- ive form there is to produce electricity. In this respect, Germany leads the world: since 1991 more than 19.460 wind power plants have been installed with a wind power capacity of 22.247 MW*. And there is more still planned for the future: away from the coastline, the offshore plants out at sea will secure future electricity supplies.

  • CHAPTER 6 Design and Development of Megawatt Wind Turbines
    CHAPTER 6 Design and development of megawatt wind turbines Lawrence D. Willey General Electric Energy Wind, USA. Electric power generation is the single most important factor in the prosperity of modern man. Yet, increasing concerns over carbon emissions from burning fossil fuels have brought large-scale renewable energy technologies to the forefront of technological development. Framework for the successful design and develop- ment of large wind turbines (WTs) addresses the world’s power generation needs. The motivation for this work, the broad framework for success, the best approach for product design, various techniques and special considerations, and develop- ment aspects are presented. Horizontal axis WTs operating inland or in near-shore applications are specifi cally addressed. 1 Introduction Supplies of fossil fuels are inadequate to meet the growing need for more power generation, which is driven by increasing demand for electricity [ 1, 2 ]. The hori- zontal axis wind turbine (HAWT) is one of the most economical forms of modern power generation. HAWTs have numerous benefi ts: they conserve dwindling fos- sil fuel resources, reduce harmful emissions, and support a sustainable electric energy infrastructure for posterity. Large wind turbines (WTs) are an engineering challenge; they must endure some of the largest numbers of fatigue cycles for structures while meeting size and cost constraints [49]. New WTs must maximize reliability, availability, maintenance, and serviceability (RAMS) while having the lowest cost of energy (CoE) and highest net present value (NPV) for a customer and an original equipment manufacturer (OEM) [50]. One of the biggest motiva- tions for accelerating technological development of WTs is in support for the U.S.

  • IEA Wind Technology Collaboration Programme
    IEA Wind Technology Collaboration Programme 2017 Annual Report A MESSAGE FROM THE CHAIR Wind energy continued its strong forward momentum during the past term, with many countries setting records in cost reduction, deployment, and grid integration. In 2017, new records were set for hourly, daily, and annual wind–generated electricity, as well as share of energy from wind. For example, Portugal covered 110% of national consumption with wind-generated electricity during three hours while China’s wind energy production increased 26% to 305.7 TWh. In Denmark, wind achieved a 43% share of the energy mix—the largest share of any IEA Wind TCP member countries. From 2010-2017, land-based wind energy auction prices dropped an average of 25%, and levelized cost of energy (LCOE) fell by 21%. In fact, the average, globally-weighted LCOE for land-based wind was 60 USD/ MWh in 2017, second only to hydropower among renewable generation sources. As a result, new countries are adopting wind energy. Offshore wind energy costs have also significantly decreased during the last few years. In Germany and the Netherlands, offshore bids were awarded at a zero premium, while a Contract for Differences auction round in the United Kingdom included two offshore wind farms with record strike prices as low as 76 USD/MWh. On top of the previous achievements, repowering and life extension of wind farms are creating new opportunities in mature markets. However, other challenges still need to be addressed. Wind energy continues to suffer from long permitting procedures, which may hinder deployment in many countries. The rate of wind energy deployment is also uncertain after 2020 due to lack of policies; for example, only eight out of the 28 EU member states have wind power policies in place beyond 2020.

  • Expectation and Review of Control Strategy of Wind Turbines Yaw System Jiatong Song School of North China Electric Power University,Baoding,071000,China
    5th International Conference on Environment, Materials, Chemistry and Power Electronics (EMCPE 2016) Expectation and Review of Control Strategy of Wind Turbines Yaw System Jiatong Song School of North China Electric Power University,Baoding,071000,China. [email protected] Keywords: Wind power generation system,yaw system,yaw control strategy,stable operation. Abstract. In recent years China's wind power industry has developed rapidly. Yaw system is an important part of the wind power generation system. Its effectiveness not only affects the wind energy capture efficiency of the system, but also related to the safe operation of the wind power system. In this article, the working principle of the yaw system is described. And the current research status of control mode in China is commented. The function of the yaw system can be divided into two aspects, one is tracing wind accurately, the other is automatic untwisting. Research indicates that, using some new control strategy, such as hill-climbing control(HCC) algorithm, PLC algorithm, fuzzy control, static neural network and many kinds of other algorithm applied to the yaw system, can enhance the stability and robust of yaw system, and increase mechanical life of yaw system. However the technology for automatic untwisting has been ignored, researching new control strategy that can trace wind precisely and achieve automatic twisting is worthy of attention. Determine whether untwisting or not and complete action through the parameters in the algorithm above can improve the economy and stability of yaw system, create great value. 1 Introduction Wind power is a clean energy,It has many advantages such as inexhaustible, renewable and environmentally friendly.

  • Aeroelastic Simulation of Wind Turbine Dynamics
    Aeroelastic Simulation of Wind Turbine Dynamics by Anders Ahlstr¨om April 2005 Doctoral Thesis from Royal Institute of Technology Department of Mechanics SE-100 44 Stockholm, Sweden Akademisk avhandling som med tillst˚and av Kungliga Tekniska h¨ogskolan i Stock- holm framl¨agges till offentlig granskning f¨or avl¨aggande av teknologie doktorsexamen fredagen den 8:e april 2005 kl 10.00 i sal M3, Kungliga Tekniska h¨ogskolan, Valhalla- v¨agen 79, Stockholm. c Anders Ahlstr¨om 2005 Abstract The work in this thesis deals with the development of an aeroelastic simulation tool for horizontal axis wind turbine applications. Horizontal axis wind turbines can experience significant time varying aerodynamic loads, potentially causing adverse effects on structures, mechanical components, and power production. The needs for computational and experimental procedures for investigating aeroelastic stability and dynamic response have increased as wind turbines become lighter and more flexible. A finite element model for simulation of the dynamic response of horizontal axis wind turbines has been developed. The developed model uses the commercial finite element system MSC.Marc, focused on nonlinear design and analysis, to predict the structural response. The aerodynamic model, used to transform the wind flow field to loads on the blades, is a Blade-Element/Momentum model. The aerody- namic code is developed by The Swedish Defence Research Agency (FOI, previously named FFA) and is a state-of-the-art code incorporating a number of extensions to the Blade-Element/Momentum formulation. The software SOSIS-W, developed by Teknikgruppen AB was used to generate wind time series for modelling different wind conditions.
