Power-Train Analysis for the DOE/NASA 100-KW Wind Turbine Generator

摘要

Progress in explaining variations of power experienced in the on-line operation of a 100-kW experimental wind turbine-generator is reported. Data are presented that show the oscillations tend to be characteristics of a wind-driven synchronous generator because of low torsional damping in the power train, resonances of its large structure, and excitation by unsteady and nonuniform wind flow. The report includes dynamic analysis of the drive-train torsion, the generator, passive driveline damping, and active pitch control as well as correlation with experimental recordings. The analysis assumes one machine on an infinite bus with constant generator-field excitation. (ERA citation 04:015890)
