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. -

The Next Generation of AEP Boost. Senvion Turbine Control Upgrade 2.0
The next generation of AEP boost. Senvion Turbine Control Upgrade 2.0. Five high-performance features increasing on average 1.8% AEP. Siemens Gamesa Renewable Energy Service is continuously developing a series of performance enhancing hardware and software technologies to help producers achieve even greater gains for their Senvion wind turbines. The new Turbine Control Upgrade 2.0 offers greater performance by increasing the Annual Energy Production (AEP) of the Senvion wind turbines by 1.8% on average*. This is possible due to further optimization of two proven features provided within the previous version of the Turbine Control Upgrade and the addition of three newly developed features. Based on the analysis of operational data, Siemens Gamesa Renewable Energy Service is able to deliver control algorithm solutions to provide yield gains. The Turbine Control Upgrade 2.0 is a bundle of performance-enhancing software products, derived from our data analysis activities. It has the following optimized and newly added features: n Smart Start n Dynamic Yaw n Adaptive Rotor Speed n Parameter Tuning n Soft Cut-Out The combination of these five high-performance features can increase the AEP of your wind farm by 1.8% on average*. New features and greater performance. The ‘Smart Start’ feature applies a self-learning algorithm which optimizes the Benefits of Senvion Turbine start-up procedure of the wind turbine to increase the energy production in the lower Control Upgrade 2.0: partial load area. The algorithm is lowering the start-up wind speed in small steps n Particularly effective for after each successful start of the turbine. -

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. -

EUR Kastrup Airport The Middelgrunden Wind Farm is situated a few kilometres away from the centre of Copenhagen. The offshore turbines are connected by cable to the transformer at the Amager power plant 3.5 km away. Kongedybet Hollænderdybet Middelgrunden Saltholm Flak 2 From Idea to Reality The idea of the Middelgrunden wind project was born in a group of visionary people in Copenhagen already in 1993. However it took seven years and a lot of work before the first cooperatively owned offshore wind farm became a reality. Today the 40 MW wind farm with twenty modern 2 MW wind turbines developed by the Middelgrunden Wind Turbine Cooperative and Copenhagen Energy Wind is producing electricity for more than 40,000 households in Copenhagen. In 1996 the local association Copenhagen Environment and Energy Office took the initiative of forming a working group for placing turbines on the Middelgrunden shoal and a proposal with 27 turbines was presented to the public. At that time the Danish Energy Authority had mapped the Middelgrunden shoal as a potential site for wind development, but it was not given high priority by the civil servants and the power utility. -
Stochastic Dynamic Response Analysis of a 10 MW Tension Leg Platform Floating Horizontal Axis Wind Turbine

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. -
