New report highlights key composite testing trends for more reliable and lower cost wind blade designs

Sandia National Laboratories recently published "Analysis of SNL/MSU/DOE Fatigue Database Trends for Wind Turbine Blade Materials, 2010-2015" by researchers at Montana State University (MSU), a long-time academic research partner. Since 1989, Sandia has collaborated with MSU to test and report key data and trends related to fiber-reinforced polymers (composites) and other materials used to construct wind turbine [...]

National Rotor Testbed aerodynamic design complete

The aerodynamic design of the National Rotor Testbed (NRT) blade has been completed (see example, above). The goal of the NRT rotor is to replicate the wake characteristics of a utility-scale rotor at the Scaled Wind Farm Technology (SWiFT) test site. This will allow researchers at Sandia and other labs to collect high-fidelity wake measurements and validate and calibrate wind turbine [...]

Wind Energy Technologies Department hosts Wakebench annual meeting

The Sandia National Laboratories Wind Energy Technologies Department is hosting the next Wakebench annual meeting (IEA Wind Task 31) at the Hotel Andaluz in downtown Albuquerque, NM, March 16-17, 2016. The meeting will include a review of wind plant and turbine model validation and verification activities in Europe and the U.S., a discussion about how to unify these [...]

A new day: SWiFT reaches rotor mounting milestone

Sandia National Laboratories has reached a major milestone by successfully re-mounting a rotor on one of its SWiFT wind turbines, a heavily modified Vestas V27, at the SWiFT facility on January 20, 2016. Wind engineers at SWiFT have been preparing for this event since 2014 when one of the turbines over sped and failed. Since [...]

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 [...]
