Mitsubishi joins Siemens, General Electric and Gamesa in their plans to opening new UK wind turbine factories following the announcement of £60m funding.
Does Wind Turbine Blade Length Really Matter?
Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the aerodynamic performance of the blade to the wind speed and the size of the blades. To calculate the amount of energy...
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 with wind and weather sensors, which record data for at least one year to help characterize long-term wind conditions. In...
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. Framework conditions More than 200,000 wind turbines were installed in the last few years associated with the worldwide...
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 ameasurement campaign on a Libellula wind plantinstalled 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 (EN 61400-12-1 – EN 61400-2). The results of this study have proven that themeasured power curvecorresponds to the theoretical curve given by Aria. The...
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 in Scotland, Denmark, and the United States invented the first wind turbines that generated electricity. Many technologic...
