摘 要：This test was conducted as part of the U.S. Department of Energy's (DOE) Independent Testing project. The project was established to help reduce the barriers of wind energy expansion by providing independent testing results for small turbines. Several turbines where selected for testing at the National Wind Technology Center (NWTC) as a part of the Small Wind Turbine Independent Testing project. Duration testing was one of up to five tests that could be performed on the turbines. Other tests included power performance, safety and function, noise, and power quality. Cascade Engineering, of Grand Rapids, Michigan, distributor of the Renewable Devices SWIFT turbine in North America, was the recipient of the DOE grant and provided the turbine for testing. The test equipment included a grid-connected SWIFT wind turbine mounted on a 13.7 meter (45-ft) free standing monopole. The system was installed by the NWTC Site Operations group with guidance and assistance from Cascade Engineering.
