E-mail: [email protected] Abstract. An 8 MW wind turbine is described in terms of mass distribution, dimensions, power curve, thrust curve, maximum design load and tower configuration. This turbine has been described as part of the EU FP7 project LEANWIND in order to facilitate research into logistics and naval architecture efficiencies for future offshore wind installations. The design of this 8 MW reference wind turbine has been checked and validated by the design consultancy DNV-GL. This turbine description is intended to bridge the gap between the NREL 5 MW and DTU 10 MW reference turbines and thus contribute to the standardisation of research and development activities in the offshore wind energy industry. 1. Introduction The LEANWIND project is focused on the application of lean principles to the offshore wind energy industry. It is anticipated that up to 14% cost reduction can be achieved by minimising waste and introducing innovative technical solutions to this rapidly developing industry [1]. An integral component of LEANWIND is the design of wind turbine support structures and service vessels for the installation, maintenance and decommissioning of offshore wind farms. In order to progress the project, it was necessary to select a reference wind turbine; data for which would be made available to all members of the consortium. Two viable options were identified, the 5 MW reference wind turbine devised by the National Renewable Energy Laboratory (NREL) [2] and the 10 MW turbine described by the Technical University of Denmark (DTU) [3]. Feedback from the LEANWIND project’s Industry Advisory Group (IAG) and consortium members indicated the need for a wind turbine sized between the NREL and the DTU in order to ensure the commercial relevance of the project at its conclusion in November 2017. To this end, a description of the LEANWIND 8 MW reference turbine (LW) was developed based primarily on published data relating to the Vestas V164 – 8 MW turbine [4]. Where data were not available, they were derived by scaling between the NREL and DTU turbines and by using engineering judgement. The LW turbine design has been validated by DNV-GL, a leading provider of independent wind turbine engineering services, using their internal conceptual turbine design tool Turbine.Architect (TA). TA is the product of over a decade of legacy Garrad Hassan experience in turbine design and comprises a suite of tools that enable accelerated design of turbine components and cost estimation. The tool operates by numerically optimizing a baseline turbine in accordance with engineering design principals and DNV-GL experience to produce a viable turbine design. The results from TA are continuously verified against available industry data to ensure the sub-models and assumptions remain relevant. An overview of the calculation process employed by TA is provided in Figure 1. Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Received: 6 September 2018; Accepted: 26 September 2018; Published: 28 September 2018 Abstract: The representation of a wind turbine power curve by means of the cumulative distribution function of a Weibull distribution is investigated in this paper, after having observed the similarity between such a function and real WT power curves. The behavior of wind speed is generally accepted to be described by means of Weibull distributions, and this fact allows researchers to know the frequency of the different wind speeds. However, the proposal of this work consists of using these functions in a different way. The goal is to use Weibull functions for representing wind speed against wind power, and due to this, it must be clear that the interpretation is quite different. This way, the resulting functions cannot be considered as Weibull distributions, but only as Weibull functions used for the modeling of WT power curves. A comparison with simulations carried out by assuming logistic functions as power curves is presented. The reason for using logistic functions for this validation is that they are very good approximations, while the reasons for proposing the use of Weibull functions are that they are continuous, simpler than logistic functions and offer similar results.

  • Investigation of Different Airfoils on Outer Sections of Large Rotor Blades
    School of Innovation, Design and Engineering Bachelor Thesis in Aeronautical Engineering 15 credits, Basic level 300 Investigation of Different Airfoils on Outer Sections of Large Rotor Blades Authors: Torstein Hiorth Soland and Sebastian Thuné Report code: MDH.IDT.FLYG.0254.2012.GN300.15HP.Ae Sammanfattning Vindkraft står för ca 3 % av jordens produktion av elektricitet. I jakten på grönare kraft, så ligger mycket av uppmärksamheten på att få mer elektricitet från vindens kinetiska energi med hjälp av vindturbiner. Vindturbiner har använts för elektricitetsproduktion sedan 1887 och sedan dess så har turbinerna blivit signifikant större och med högre verkningsgrad. Driftsförhållandena förändras avsevärt över en rotors längd. Inre delen är oftast utsatt för mer komplexa driftsförhållanden än den yttre delen. Den yttre delen har emellertid mycket större inverkan på kraft och lastalstring. Här är efterfrågan på god aerodynamisk prestanda mycket stor. Vingprofiler för mitten/yttersektionen har undersökts för att passa till en 7.0 MW rotor med diametern 165 meter. Kriterier för bladprestanda ställdes upp och sensitivitetsanalys gjordes. Med hjälp av programmen XFLR5 (XFoil) och Qblade så sattes ett blad ihop av varierande vingprofiler som sedan testades med bladelement momentum teorin. Huvuduppgiften var att göra en simulering av rotorn med en aero-elastisk kod som gav information beträffande driftsbelastningar på rotorbladet för olika vingprofiler. Dessa resultat validerades i ett professionellt program för aeroelasticitet (Flex5) som simulerar steady state, turbulent och wind shear. De bästa vingprofilerna från denna rapportens profilkatalog är NACA 63-6XX och NACA 64-6XX. Genom att implementera dessa vingprofiler på blad design 2 och 3 så erhölls en mycket hög prestanda jämfört med stora kommersiella HAWT rotorer.

In free decay motion, viscous drag reduces the amplitude of pitch and roll fluctuation, the quasi-static mooring system overestimates the resonant amplitude values of pitch and roll. In this paper, the quasi-static mooring system is modified by introducing linear damping and quadratic damping. The dynamic response characteristics of the FHAWT modified model of the DTU 10 MW tension leg platform (TLP) were studied. Dynamic response of the blade was mainly caused by wind load, while the wave increased the blade short-term damage equivalent load. The tower base bending moment was affected by inclination of the tower and the misaligned angle bwave between wind and wave. Except the yaw motion, other degrees of freedom motions of the TLP were substantially affected by bwave. Ultimate tension of the mooring system was related to the displacement caused by pitch and roll motions, and standard deviation of the tension was significantly affected by the wave frequency response.

    Floating Offshore Wind 101 Webinar Q & A This Q&A document is based on the webinar, Floating Offshore Wind Overview. Cost and Economics Questions Answers Can you comment on the recent report that characterizes offshore wind in the We are unaware of the report being referenced, but we can say recent cost declines in Europe have been United States as too expensive? Is the industry positioned to counter that verified by NREL’s analysis of the revenue generated from negotiated power purchase agreements for assertion? the first few U.S. offshore wind projects suggest offshore wind: 1. Is no more expensive in the United States than in Europe 2. May soon be competitive in many electric markets, especially in the Northeast 3. May be able to provide additional benefits to the utility system, especially in constrained energy markets. What are the most likely financing schemes for U.S. utility-scale projects For early commercial-scale floating wind projects (e.g., those in the mid-2020s), we expect project starting construction in the mid-2020s or later without the benefit of federal tax financing arrangements that are similar to today’s financing of fixed-bottom wind projects in the United credits? Is a single-owner power purchase agreement the most likely financing States. The benefits of the fading tax credits will have to be compensated through other means to make mechanism, absent the past tax benefits for flip structures? projects bankable. These other means include lower costs or technology-specific, state-mandated power purchase agreements or offshore wind renewable energy certificates, which are known as ORECs, and they may need to be used in combination with public financing.

  • 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.
