  • Spin Doctors: How GE’s Service-Savvy Approach Squeezes the best from a fleet of 900 Wind Turbines

    Over 150 years ago, a budding English economist named William Stanley Jevons warned that a policy of energy efficiency might not be sufficient to conserve Britain’s dwindling coal reserves. His argument, now known as the Jevons paradox, was simple: Squeeze more energy from less coal, and people will just want more coal. ...

  • Wind turbines cause rising number of bird and bat fatalities

    Wind power is one of the cleanest and safest methods of generating renewable energy. Due to the steady increase in price of nonrenewable sources, wind turbine use has increased 25% in the past decade.i While its growth has helped reduce carbon emissions and pollution, this green source of energy comes at a cost: these massive blades, slicing the air at close to 200 miles per hour, serve as ...

  • 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. ...

  • Power curve measured and verified – Case Study

    In 2010 RSE SpA (Energy System Research Inc.) within a Program Agreement with the Italian Ministry of Economic Development started a measurement campaign on a Libellula wind plant installed in Tuscany. The campaign lasted 1 ½ years and during this time RSE measured the turbine’s power curve following the requirements of the relevant IEC Standard ...

  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...

  • Helplessly exposed to nature? How lightning storms can be measured

    Each day, there occur about 1,000 thunderstorms with 4-10 million lightning bolts worldwide. In average, 700 people per year are hit by such light discharges, of which 75% of the hits result in long-term damages. Between three and seven cases end fatal. The risk is particularly high in the open field and is fortunately decreasing. The reason for this is that we stay more often inside in cars and ...

  • Small Wind Turbines tested: “Fortis Montana best performance”

    The market for commercial wind turbines is maturing even as they get bigger and bigger, but the market for small wind turbines is quite young, with some people comparing it to the car industry early in the 19th century. Although some manufacturers have been in the business for over two decades, most suppliers are from this millennium. And that shows. As in most immature markets, there are ...

  • 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 ...

  • Reducing avian collisions with wind turbines

    Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

  • Terminal characteristics of type 1 wind generating systems with magnetic saturation

    This paper proposes a simple method of incorporating magnetic saturation in determining terminal characteristics of a type 1 wind generating system employing a squirrel–cage induction generator. In determining the terminal characteristics, the generator is represented by its traditional per–phase equivalent circuit as well as two–axis model. In both cases, the magnetic saturation is carefully ...

  • The Real Cost Associated With Neodymium Wind Turbines

    According to a research organized by a group of UK scientists, it is predicated that 15% of the country’s energy requirements in the year 2020 are expected to come from renewable energy sources. They have also considered about the wind farms that are popping in every corner of the country to come into this conclusion. These reports have created several contradictions among people as well. ...
