  • 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 ...


  • 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 ...

  • 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 ...

  • Rising offshore plant capacities lead to greater data-based O&M gains

    The growing size of offshore wind farms provides greater scope for data optimisation during Operations and Maintenance, while software solutions can also help mitigate risk during the development phase, Marcus Ihle, Senior Consultant at Outsmart, said. Further gains could be made if operators share more data from their growing databases with other plant owners, Ihle said. The ...

  • 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 ...

  • Mapping the climate change industry-an ethical corporation special report

    Climate change has gone from being a marginal issue to being at the forefront of business leaders’ minds. The scientific evidence has been growing for years and 2007’s IPCC reports appear to have settled the debate about whether man-made climate change is happening. However, the issue’s move to the centre stage has come about thanks to a range of disparate events, including hurricanes Rita and ...

  • Underwater Robots Perfect for Power Production

    Underwater exploration, fish farms, dive jobs, marine research, municipal and commercial water utilities are obvious industries for the utilization of Deep Trekker mini-ROVs and pipe crawlers. However another industry that has seen remarkable success integrating underwater inspection robots is energy production. Diverse methods of creating energy provide a number of applications which benefit ...

  • 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 ...

  • PULSE smart start – a user’s experience

    Measuring on a Grounded Aeroplane   In the early days of PULSE, a team from Brüel & Kjær had the opportunity of performing a ground test on a Boeing 767. The left engine of the aeroplane had undergone a scheduled overhaul. The engine was reassembled and verified in a test cell. Everything seemed fine. The engine was mounted on the aeroplane and the aeroplane was ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • 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 ...
