Institute for Advanced Composites Manufacturing Innovation—Inaugural Members Meeting

Sandia Wind Department technical staff members Josh Paquette and Brian Naughton attended the inaugural members meeting for the newly formed Institute for Advanced Composites Manufacturing Innovation (IACMI) in Knoxville, Tennessee. A few hundred attendees from the composites industry, academic institutions, and government agencies gathered to learn about opportunities to participate in the newest National Network for [...]

SWiFT Facility Prepared for More-Efficient Operations & Advanced Turbine-Turbine Wake-Interaction-Control Research

The SWiFT facility comprises three heavily instrumented and modified variable-speed, variable-pitch Vestas V27 turbines and two 60 m anemometer towers, with the first two turbines spaced three diameters apart, perpendicular to the prevailing oncoming wind, and the third turbine five diameters downwind (the turbines form a three, five-, six-rotor-diameter-length triangle). Two turbines are funded [...]

Version 24 of the Composite Materials Database Now Available for Download

Montana State University researchers have added acoustic emission and digital image correlation instrumentation to enhance the data collection capabilities of the substructure test fixture. Wind-turbine blade growth continues to have the largest impact on energy capture and levelized cost of energy (LCOE) reduction. While the 40–45 meter blade is today’s mainstream segment, it [...]

New Small Business Voucher Pilot Opens

The highly anticipated Department of Energy (DOE) Small Business Vouchers (SBV) pilot opens for business today. Through the pilot, small businesses can apply to access the Department’s world-class facilities and an enterprise of more than 10,000 leading scientists and engineers at the National Renewable Energy Laboratory and Lawrence Berkeley, Oak Ridge, Pacific Northwest, and Sandia national laboratories. [...]

Sandia Wake-Imaging System Successfully Deployed at Scaled Wind Farm Technology Facility

The Sandia Wake-Imaging System (SWIS) was deployed for a full-scale field demonstration at the Sandia Scaled Wind Farm Technology (SWiFT) facility in Lubbock, Texas, in July. This successful field demonstration was a culmination of over 3 years of technical development; more than a year of safety, environmental, and regulatory approvals; and the efforts of 20 [...]

Sandia’s Energy Program Wins Two Federal Laboratory Consortium 2015 Awards

Sandia’s Energy Program has won two awards from the Federal Laboratory Consortium for Technology Transfer’s (FLC’s) Far West Region for its work to develop and commercialize innovative technologies. The FLC is a nationwide network of ~300 federal laboratories and centers that provides a forum to develop strategies and opportunities for linking laboratory mission technologies and [...]

Government-Industry Radar/Airspace Listening Session at WindPower2015

Representatives from the federal agencies participating in the Wind Turbine Radar Interference Mitigation (WTRIM) Working Group held a special Government-Industry Radar/Airspace Listening Session at the American Wind Energy Association AWEA WindPower 2015 event in Orlando, Florida. The event was well attended by more than 50 persons (other than the panel members). The panel consisted of [...]

Upcoming Release of the University of Minnesota’s Virtual Wind Simulator

Large-eddy simulation (LES) of wind farms with wind-turbine parameterization is emerging as a powerful tool for improving existing wind farm performance and lowering maintenance costs—and assessing the potential sites for installing wind farms. Sandia is working with the University of Minnesota (UMN) St. Anthony Falls Laboratory to document and prepare UMN’s offshore version of the [...]

Sandia Wind-Turbine Blade Flaw Detection Experiments in Denmark

Wind-turbine blades pose a unique set of inspection challenges: from very thick and attentive spar-cap structures to porous bond lines, varying core material, and a multitude of manufacturing defects of interest. The need for viable, accurate, nondestructive inspection (NDI) technology becomes more important as the cost per blade—and lost revenue from downtime—grows. Under its Blade [...]

Structural Health Monitoring and Prognostics Management for Offshore Wind Plants

Offshore wind energy could potentially play a significant role in helping the nation establish a diversified energy-generation portfolio composed of clean, renewable resources. A current obstacle to offshore wind energy is that most projections put offshore wind farm operations and maintenance (O&M) costs between 2 to 5 times the current average O&M costs for onshore [...]
