Control system design for a variable speed yaw controlled wind turbine
- Univ. of Texas, El Paso, TX (United States); and others
The combination of variable speed operation and yaw control for power regulation is an interesting option for two-bladed teetered rotor wind turbines. The Italian Gamma 60 turbine, for example, is a 60 meter diameter turbine with these features. The 7.6 m diameter teetered rotor test facility at the University of Texas at El Paso is in the process of being fitted with a mechanical variable speed transmission and power electronics for an induction generator to investigate these two variable speed options. The test bed also has a yaw drive system that is capable of regulating power and loss of load overspeed by passive yaw control. One significant finding of the control study presented in this paper is an indication that suitable combinations of shaft uptilt and thrust offset together with variable speed operation may allow the design of a downwind, free-yaw turbine with passive yaw control for overspeed protection. The results are preliminary, however, and further investigation is required to determine the free yaw characteristics over the full range of wind speeds.
