  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Ferrography Made Easy With The FerroCheck 2000

    The measurement and trending of abnormal ferrous wear debris in machinery lubrication oils is arguably the most significant indicator of machinery health and a key predictor of catastrophic machinery failure. There are several methods available to measure the ferrous content of lubrication oil. ...

  • Wind modelling based on wind input data conditions using Weibull distribution

    Weibull distribution can be used to model the wind speed distribution at a particular site and hence, it can help in wind resource assessment (WRA) of a site. By calculating the shape (k) and scale (c) parameters for Weibull distribution, the wind speed frequency curve for a site can be made. Once this wind speed distribution for site is determined, it can be convolved with the power curve for a ...

  • On the probabilistic distribution of wind speeds: theoretical development and comparison with data

    The probabilistic distributions of wind speed are a critical piece of information needed in the assessment of wind-energy potential, and have been conventionally described by various empirical correlations. Among the empirical correlations, the Weibull distribution has been most popular due to its ability to fit most accurately the variety of wind-speed data measured at different geographical ...

  • Parameterisation of convective PBL using surface data for the wind and stability classes

    A simple two-layer model of convective planetary boundary layer (CPBL), consisting of a Surface Layer and an Ekman layer over it and developed in accordance with the similarity theory is used to obtain the vertical profiles of the temperature, wind velocity and the turbulent exchange coefficient in CPBL from the surface wind measurements and atmospheric stability data. As input to this model the ...

  • Data–driven modelling, control, and fault detection of wind turbine systems

    In this paper, data–driven system modelling, control, and fault detection technique for wind turbine systems are researched. The developed algorithm is to recursively update system parameters using predictor–based system identification (SID) technique. Updated system parameters are used to design subspace predictive controller for wind turbine systems with constraint on pitch angle and generator ...

  • Exergy analysis of a wind turbine

    The present paper deals with a developed and improved approach for exergy analysis of the wind. Based on this model, a typical wind turbine model (Bergey Excel-S) is assumed to be installed in two cities in Iran. The results show that, with regard to the annual average wind data, if the wind turbine is installed in Tehran, by varying the cut in, rated and furling speeds from 3.1, 13.8 and 15.6 ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Weather claims and wind safety

    Anybody working in the construction industry either here in the UK or anywhere else in the world is likely to know that the weather can present us with particular hazards. While rain, ice and snow are particularly dangerous to work in, we must always be aware that the wind is also likely to make conditions unsafe, particularly for those who work at height and those who ...

  • Mapping the power of wind

    Online mapping solutions are playing a growing role in the search for wind farm locations, says Justin Saunders of eMapSite. MORE than a dozen renewable energy applications have been approved by the Scottish Government since May 2007 in what Energy Minister Jim Mather has called a “renewables surge”. This autumn’s opening of the Dalswinton and Minsca wind farms in Dumfries and Galloway is the ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Wind Surpasses Nuclear in China

    Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Drones for Wind Turbine Inspection

    Unmanned Aerial Vehicles and Inspection Services for Wind Turbines: Global Market Assessment and Forecasts By the beginning of 2015, there were nearly 270,000 individual wind turbines operating globally. The more than 800,000 blades spinning on these turbines are battered by the elements over time and gradually wear out. Deterioration can cause reduced energy ...

  • The Future Cost of Wind Power

    Chapter 1 The economics of wind power Wind power is capital intensive with most of the investment required upfront. The largest capital cost component is the turbine itself which can account for between 40% and 80% of the total capital cost of an onshore wind installation. Costs offshore are higher because of the more expensive operating environment and the greater difficulty establishing ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Compilation of wind energy assessment software and wind energy assessment in the northwest of Iran

    Development trend of wind data assessment software, Visual WIDA®, is discussed in this paper. In the beginning, theories and standards required for wind energy assessment which are used in the software are introduced and some methods provided by the writers for the calculation of the main parameters are described. Afterwards, capabilities of Visual WIDA are illustrated in detail. In this ...

  • Verification of Wind-Driven Volatilization Models

    Abstract  Mass-transfer processes of paramount importance, such as reaeration and volatilization, occur at the air–water interface. Particularly, volatilization is intensively studied because it can be a relevant removal process for toxic contaminants from flowing and standing surface waters. The paper provides a comparison among predictive equations available from literature for standing ...
