  • 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. ...

  • Finite element analysis of turbine generator rotor winding shorted turns

    Abstract Online magnetic flux monitoring via permanently installed air-gap flux probes is a well- established technology to determine the presence of shorted turns in a turbine generator rotor winding. Flux measurements are normally performed using flux probes installed in the machine air gap (on a stator wedge) and connected to portable or permanently installed instruments. In this ...

  • 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 ...


  • 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 ...


  • Innovation risk slows offshore wind foundation development

    As offshore wind technology develops ever more gigantic machines further from shore into deeper waters, it is common wisdom that new foundation technologies are needed. But are they? Monopile, and some jacket foundations, still dominate the offshore wind market in commercial operation. Prototype floating foundations are performing well in demo or pilot projects, but scaling up is only ...

  • Integrated solar and wind energy powers oil recovery system

    Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...

  • Continuous, Centralized Monitoring Drives O&M Optimization

    In a survey conducted by Wind Energy Update this year, 80% of wind turbine owners indicated they take either a predictive or preventative approach to maintenance. Furthermore, 77% indicated that they deploy Condition Monitoring Systems (CMS). “If you can leverage data to increase plant performance by even 1%, you are looking at significant impacts to your revenue”, EDF’s ...

  • Wind power has increased by 175 MW in Spain in 2013, the lowest rate of growth in 16 years

    The wind sector installed 175 MW in Spain in 2013, up 0.77% on a year-by-year basis. This is the lowest growth rate in the sector since 1997, the year in which it was regulated for the first time in the Electrical Sector Law. On December 31st total accumulated power in the sector stood at 22,959 MW according to data compiled by the Spanish Wind Energy Association (AEE). This installed power is ...

  • Automating oil particle analysis

    Run up to 25 samples at one time The major issue for premature failure in wind turbine gearboxes is bearing failure, which leads to gearbox failure. A wind turbine gearbox will not survive if the oil is ...

  • Spares storage can halve downtimes, cut purchase prices

    The advanced purchase and storage of spare-parts can halve the number of downtime days for a typical wind farm and costs can be controlled by buying in bulk and sourcing from a wider market base including refurbished products, Derck van Ommeren, head of sales for the Dutch spares provider WindTurbineSpareParts.com, told Wind Energy Update. It may not be cost effective to keep a full set of spare ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

  • UE: risk of shortage for 8 rare earth metals

    In a report published on November 4th, the European Joint Research Centre (JRC) has warned of the "risk of shortage" in 2020-2030 of eight strategic metals used in low carbon energy technologies identified in the European SET Plan adopted in 2008. This report continues the work done in a previous study of the JRC from 2011. It is also based on the scenarios presented in 2011 in the roadmap of ...

  • Urban sustainability issues — Resource-efficient cities: good practice

    Our current pattern of resource use is leading to the depletion and, consequently, scarcity of natural resources (1), the degradation of ecosystems and volatile and increasing prices of natural resources. On a planet with finite resources, the challenge is to find a way of delivering greater value and more services with fewer inputs (EC, 2011a). Resources are defined as raw materials, such as ...

  • Can we bury the carbon dioxide problem?

    Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled ...
