摘要：
The hybrid drive wind turbine（HDWT） equipped with the speed regulating differential mechanism is able to employ synchronous generator to achieve friendly grid-connected consumption of wind power without power electronic frequency conversion devices. In order to further improve the grid-connected operation performance of the new type HDWT，combined with the backstepping design method and sliding mode control theory，a backstepping sliding mode excitation control method suitable for the HDWT generating unit is proposed. By combining the extended state observer with the proposed backstepping sliding mode control theory，the undesired influences of model parameter uncertainty in the control system and the disturbances from wind wheel and grid sides can all be well-compensated. The Lyapunov criterion is constructed and the global asymptotic stability of the control system is proved. The simulation model and semi-physical test platform of a 1.5 MW HDWT are built，and the control effect of the proposed control method is compared and verified. The results show that under different wind speed conditions and grid faults，the proposed backstepping sliding mode excitation control method can better improve the grid-connected operation performance of HDWT. © 2023 Electric Power Automation Equipment Press.
