Torque ripple in a vertical axis wind turbine
Technical Report
·
OSTI ID:6875018
Torque ripple is a name given to time variations in torque which are propagated through the drive train of wind energy conversion systems. An analytical and experimental investigation of torque ripple in a Darrieus vertical axis wind turbine is presented. An analytical model of the turbine is described and numerical results from a solution to the equations of this model are compared to experimental results obtained from the existing DOE/Sandia 17 meter vertical axis wind turbine. Discussions on the sources of torque ripple, theoretical and experimental correlation, and means of suppressing its magnitude are included.
