AWS Truepower Releases Major Upgrade to openWind® Enterprise Wind Project Design and Optimization Software

New edition addresses challenges of complex sites, accepts remote-sensing data, and expands environmental analysis capabilities

ALBANY, N.Y., Jan. 14, 2014 /PRNewswire/ -- AWS Truepower, LLC, an international leader in renewable energy consulting and information services, announced a major upgrade to its openWind Enterprise wind project design and optimization software. Among other features, the new edition incorporates the latest IEC recommendations on effects of turbulence and shear on turbine output; the ability to use wind profiles to 200 m from sodar, lidar, and tall towers; and expanded environmental analysis including time-series modeling of shadow flicker and improved noise modeling and reporting.

"The new software enables the analyst to apply adjustments to turbine output for unusual or extreme turbulence and shear based on the latest IEC-recommended methods," explains Nick Robinson, Director of openWind at AWS Truepower and the lead developer. "Now, for each time step, the software calculates the rotor equivalent wind speed and turbulence adjustment based on multi-height wind profiles such as you might get from a lidar, sodar, or tall tower."

"Just as important," Robinson continues, "the framework we've built provides room for user flexibility and a staging point for continued improvements – for instance, incorporating time-varying thermal stability in wake loss calculations."

"This upgrade is aimed squarely at handling complex sites with very large turbines – just the type of situation our Enterprise customers are increasingly facing," said Michael Brower, Chief Technical Officer at AWS Truepower. "I think our customers will be delighted with the new capabilities, many of which respond to their urgent requests in dealing with real-world projects," Brower concluded.
