Serpetsidakis, Michail I. (2005) Dynamic analysis of an active furling small wind turbine. (MSc(R) thesis), Kingston University.Full text not available from this archive.
This study examines the dynamic behaviour of a small wind turbine. A mathematical model is developed to describe the small wind turbine's yaw behaviour. Two cases are examined, a small wind turbine system with a stationary rotor and a small wind turbine system with the rotor producing power. The occurred phenomena during the small wind turbine's operation are presented and explained. The relative simplicity that characterises the first model allowed an analytical method to be applied. The non linearity of the second model dictated a numerical method to be used. Two small wind turbine dynamic behaviour codes were programmed using the developed mathematic models. In the same time an active furling small wind turbine was instrumented and a number of dynamic tests was performed. The dynamic tests took place with stationary and rotating rotor. Two different dynamic tests procedures were performed with the rotor producing power. The difference between these procedures was the tail boom's geometry. During these tests the active furling system was disabled. The small wind turbine system was measured using constant furling angles. The acquired measurements were analysed and a bin process was applied to clarify the occurred phenomena. The measured data were used to verify the mathematical models. Two micro wind turbine models were tested in a wind tunnel under static yaw conditions. The two micro wind turbine models were especially developed to measure rotor loads. The acquired measurements were used to verify the mathematical submodels that calculate the rotor loads. The micro wind turbine models were also used for wake visualization tests at yawed flow cases.
