A Model of Wind Turbine’s Flexibility Shaft

Abstract:

Wind power is a new technology compared with thermo power, the damage of sub-synchronous oscillations cloud bring to the shaft of wind turbine do not get enough notices. There are few studies on wind turbines sub-synchronous oscillation now, which are built on the model of rigid shaft. As we all know wind turbine shaft is unlike the shaft of stream turbine, there are couplings and gearbox in wind turbine which make the shaft flexible, so the studies of wind turbine sub-synchronous oscillations based on rigid shaft model are not reasonable, this paper introduces a new flexible shaft model for studying of wind turbine sub-synchronous oscillations. Flexible equipments, such as joints and gearbox are taken into consideration when the model are set up, so this model is far more scientific.
