Acoustic Noise Test Report for the SWIFT Wind Turbine in Boulder, CO

Description: This report summarizes the results of an acoustic noise test that the National Renewable Energy Laboratory (NREL) conducted on the SWIFT wind turbine. This test was conducted in accordance with the International Electrotechnical Commission's (IEC) standard, Wind Turbine Generator Systems Part 11: Acoustic Noise Measurement Techniques, IEC 61400-11 Ed.2.1, 2006-11. However, because the SWIFT is a small turbine, as defined by IEC, NREL used 10-second averages instead of 60-second averages and utilized binning by wind speed instead of regression analysis.

Establishment of Small Wind Regional Test Centers: Preprint

Description: The rapid growth of the small wind turbine (SWT) market is attracting numerous entrants. Small wind turbine purchasers now have many options but often lack information (such as third-party certification) to select a quality turbine. Most SWTs do not have third-party certification due to the expense and difficulty of the certification process. Until recently, the only SWT certification bodies were in Europe. In North America, testing has been limited to a small number of U.S. Department of Energy (DOE) subsidized tests conducted at the National Wind Technology Center (NWTC) under the ongoing Independent Testing Project. Within the past few years, the DOE, National Renewable Energy Lab (NREL), and some states have worked with the North American SWT industry to create a SWT certification infrastructure. The goal is to increase the number of certified turbines and gain greater consumer confidence in SWT technology. The American Wind Energy Association (AWEA) released the AWEA Small Wind Turbine Performance and Safety Standard (AWEA Standard 9.1 - 2009) in December 2009. The Small Wind Certification Council (SWCC), a North American certification body, began accepting applications for certification to the AWEA standard in February 2010. To reduce certification testing costs, DOE/NREL is providing financial and technical assistance for an initial round of tests at four SWT test sites which were selected via a competitive solicitation. The four organizations selected are Windward Engineering (Utah), The Alternative Energy Institute at West Texas A&M (Texas), a consortium consisting of Kansas State University and Colby Community College (Kansas), and Intertek (New York). Each organization will test two small wind turbines as part of their respective subcontract with DOE/NREL. The testing results will be made publically available. The goal is to establish a lower-cost U.S. small wind testing capability that will lead to increased SWT certification.

Certification testing at the National Wind Technology Center

Description: The International Electrotechnical Commission is developing a new standard that defines power performance measurement techniques. The standard will provide the basis for international recognition of a wind turbine`s performance primarily for certification, but also for qualification for tax and investment incentives, and for contracts. According to the standard, the power performance characteristics are defined by a measured power curve and by projections of annual energy production for a range of wind conditions. The National Wind Technology Center (NWTC) has adopted these power performance measurement techniques. This paper reviews the results of the NWTC`s first test conducted under the new protocol on the Atlantic Orient Corporation`s AOC 15/50 wind turbine at the NWTC. The test required collecting sufficient data to establish a statistically significant database over a range of wind speeds and conditions. From the data, the power curve was calculated. Then the results from a site calibration procedure determined the flow distortion between winds measured at the turbine location and those measured at the meteorological tower. Finally, this paper discusses the uncertainty analysis that was performed in accordance with the standard. Use of these procedures resulted in the definition of the AOC 15/50`s power curve within about 3 kW.

Expanding Small Wind Turbine Certification Testing - Establishment of Regional Test Centers (Poster)

Description: Presented at the WINDPOWER 2010 Conference & Exhibition, 23-26 May 2010, Dallas, Texas. The rapid growth of the small wind turbine (SWT) market is attracting numerous entrants. Small wind turbine purchasers now have many options but often lack information (such as third-party certification) to select a quality turbine. Most SWTs do not have third-party certification due to the expense and difficulty of the certification process. Until recently, the only SWT certification bodies were in Europe. In North America, testing has been limited to U.S. Department of Energy (DOE) subsidized tests conducted at the National Wind Technology Center (NWTC) under the ongoing Independent Testing Project. The goal is to increase the number of certified turbines and gain greater consumer confidence in SWT technology. To reduce certification testing costs, DOE/NREL is assisting in establishing a network of Regional Test Centers (RTCs) to conduct SWT third-party certification testing. To jump-start these RTCs, DOE/NREL is providing financial and technical assistance for an initial round of tests. The goal is to establish a lower-cost U.S. small wind testing capability that will lead to increased SWT certification. This poster describes the project, describes how it fits within broader SWT certification activities, and provides current status.

Small Wind Turbine Testing Results from the National Renewable Energy Laboratory: Preprint

Description: In 2008, the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) began testing small wind turbines (SWTs) through the Independent Testing project. Using competitive solicitation, five SWTs were selected for testing at the National Wind Technology Center (NWTC). NREL's NWTC is accredited by the American Association of Laboratory Accreditation (A2LA) to conduct duration, power performance, safety and function, power quality, and noise tests to International Electrotechnical Commission (IEC) standards. Results of the tests conducted on each of the SWTs are or will be available to the public on the NREL website. The results could be used by their manufacturers in the certification of the turbines or state agencies to decide which turbines are eligible for state incentives.
