A supplier of ultracapacitors has introduced a 160V ultracapacitor module to provide energy storage and power delivery for wind turbine pitch control, short-term uninterrupted power supply (UPS) and renewable energy systems. Primarily targeted at pitch control systems for 1.5 to 3 MW wind turbines, the 5.1 kg, 160V module provides a turnkey solution to simplify [...]
The American Council On Renewable Energy (ACORE) released the 2012 edition of its report, Renewable Energy in the 50 States, as an interactive, online resource. Compiling updated financial data, resource potentials, market and policy information in one easily-accessed, online format, the report is intended to be an executive summary for all who are interested in [...]
The VJ-Advance sports an ultra-compact, portable video borescope with 360-degree camera articulation, and medical-grade 640 x 480 image resolution. Ideal for wind-turbine inspections, the borescope can come with insertion tubes ranging from 1.5 to 5.0-m in length and 3.9 or 6.9-mm dia. It features joystick-controlled four-way articulation and can capture on-board images, video, and audio. [...]
Wind turbine manufacturer, REpower Systems SE (www.repower.de), has commissioned its tallest wind turbine to date. Located in Bavaria at the Winnberg site, the turbine has a power rating of 3.2MW, a rotor dia. of 114m, and it sits on a 143-m concrete and steel hybrid tower. Rotor tips will reach to a height of 200m. [...]
A Tunisian-based wind energy company specializing in R&D has developed a radical way to capture the wind power. The Saphonian, an unusual zero-blade design, offers a clean, efficient, and cost-effective way to produce wind energy, says Saphon Energy (www.saphonenergy.com). This concept removes the rotating devices (blades and hub) and replaces them with a non-traditional body [...]
Independent U.S.-based wind energy project developer, First Wind (www.firstwind.com), will soon contribute to the renewable energy market and more in Washington state with the completion of the Palouse Wind Farm. Located in Whitman County, the 105MW project has the capacity to power up to 30,000 homes and over a $1 million each year in revenue [...]
Major gearbox component failures entail the largest of wind turbine repair costs. Failures such as overheating and contact fatigue cause turbine downtime and result in a loss of revenue. O&M costs can significantly increase over a turbine’s lifecycle. For example, costs are 10 to 15% of production costs and grow to 20 to 35% later [...]
A supplier of megawatt-class permanent magnet generator and full-power converter packages for wind power and other renewable energy applications, says it has been chosen by the Global Cleantech Cluster Association (GCCA) as the 2012 Later Stage Award Global Best of Wind winner. The 2012 Global Top 10 award reflects The Switch’s cleantech success and market [...]
The most volatile timeframe for something “bad” to happen in a project’s lifecycle is during construction, which makes securing proper builder’s risk coverage extremely important. Builder’s risk coverage is protection for equipment and materials that will become part of a final project up to the Commercial Operation Date (COD). Such coverage includes turbines, foundation, transmission, [...]
Proficy SmartSignal Shield 4.0, software for wind power and other industries, helps large equipment operators detect equipment problems early and avoid surprise equipment failure, thereby increasing productivity while minimizing costs. The software provides early warning of impending equipment problems, diagnostic guidance, and prioritized actionable intelligence. The software is said to let users move from reactive [...]
With a broad measurement range of -40° to 1076°F (-40° to 580°C), the new 12:1 Wide Range Infrared Thermometer (IRT657) is well suited for testing and troubleshooting a wide variety of systems and components. This precision point-and-shoot, gun-style infrared thermometer accurately and easily measures surface temperatures—including hot, cold or inaccessible equipment—from a safe distance. The [...]
