Boeing, under contract to the Electric Power Research Institute (EPRI), has completed a test and analysis program on the Mod-2 wind turbines at Goodnoe Hills, Washington. The goal was to make a structural and mechanical assessment of the machines. This was accomplished by updating the loads data base and determining the effects of site and machine differences and vortex generators on fatigue life estimates. Two yaw loads alleviation techniques were also evaluated. This report briefly describes the test setup and loads instrumentation, but it emphasizes the loads data comparisons and their relevance to Mod-2 fatigue life estimates. Comparisons of these data with dynamic loads data from a similar test program on the Pacific Gas and Electric Company (PG and E) Mod-2 wind turbine in Solano County, California, are included to illustrate site differences. Pretest predictions based on the DYLOSAT computer program are shown. Mean and fatigue load spectra in the form of wind bin plots are developed for the major structural components to compare data. The report concludes with an assessment of the importance of vortex generators, site dependence, and machine differences on fatigue load and life predictions. The adequacy of structural analysis methodology used on Mod-2 is evaluated, and recommendations are made to improve this methodology for application to horizontal-axis wind turbine design.
