Abstract
A rotary kite airborne wind energy (AWE) system is
equipped with a tensile rotary power transmission (TRPT) unit
for torque transmission from the tethered airborne components
to the ground generation station. A lift kite is attached to the
rotor and TRPT system playing crucial functions during system
launching, landing and in-air operations. The aim of this work is
to investigate the operation requirements of the lift kite through
steady-state analysis at equilibrium points of given wind speeds
and a selected elevation angle. The equilibrium model includes
the balance of forces in the TRPT axial direction to enable
the torque transmission from the turbine rotor to the ground
electrical generator and the moment equilibrium in the direction
perpendicular to the rotation axis of the TRPT. These two
conditions together determine the lift kite operation requirements
meant to provide the structural stiffness for torque transmission,
prevent the system from over-turning and maintain the system
positioning to achieve most efficient power generation. Simulation
studies are conducted using a model developed for a prototype
system manufactured and field tested.
