Leading Edge Erosion Phase II Wind Tunnel Test Begins

Wind tunnel testing is commencing for the second phase of the leading edge erosion project, which is a collaboration between Texas A&M, UC Davis, and Sandia. During the 2012 fiscal year, Sandia, through its Blade Reliability Collaborative, partnered with a wind turbine operator and associated wind turbine manufacturer to study the effects of blade erosion [...]

Texas Tech University mobile doppler radars provide unique wind measurements to multi-instrument DOE Field Campaign

Over the past few years, Texas Tech University researchers have been collecting and analyzing dual-Doppler wind speed and direction data from operating wind plants using their unique Ka-band (TTUKa) mobile Doppler radars. Researchers have documented features of complex flow including turbine wakes, turbine-to-turbine interaction, wind speed ramps, and small-scale gust/lull features called "streaks." Their valuable [...]

Wind Plant Optimization: SWiFT Restart Technical Review Committee

The SWiFT Facility passed a critical milestone towards a complete restart of operations with the approval to re-mount rotors and complete the commissioning. The SWiFT Restart Technical Review Committee granted the approval when they met at the SWiFT Facility in Lubbock, TX, on November 12-13, 2015 (see Figure 1, below). The committee included members from [...]

New CREW Database Receives First Set of Data

The CREW public benchmark represents analysis of US wind fleet performance based on aggregated fleet reliability data. Sandia’s Continuous Reliability Enhancement for Wind (CREW) project has received its first large set of data, which reassessed its data-collection efforts to target wind-farm owner/operators that have in-house reliability data collection tools. After a lengthy negotiation [...]

Aerodynamic Wind-Turbine Blade Design for the National Rotor Testbed

The NRT blade shape as viewed from the tip and at an elevation angle of 30° above the suction surface. Sandia has designed a new wind-turbine blade for the National Rotor Testbed (NRT) project and for future experiments at the Scaled Wind Farm Technology (SWiFT) facility with a specific focus on scaled wakes. [...]

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 [...]

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 [...]
