To enhance the seismic resilience of onshore wind turbines, this study proposed a partial self-centring onshore wind turbine (PSCOWT) by the incorporation of an innovative energy dissipation tower module (EDTM). The EDTM consisted of a reduced tower section (RTS) and partial self-centring dampers (PSCD). Firstly, the concept and working mechanism of the PSCOWT were presented. Then, a nonlinear finite element modelling framework was developed for both a 1.5 MW conventional onshore wind turbine (OWT) and PSCOWT prototype structures, and the rationality of the modelling techniques was verified through comparison with experimental data. Finally, the seismic performance of the prototype structures was carefully examined in terms of nonlinear static analyses and nonlinear dynamic analyses. The hysteretic behaviour of the PSCOWT exhibited partially self-centring characteristics and significantly enhanced structural ductility compared to the conventional OWT. Dynamic analysis results showed that, compared to the conventional OWT, the PSCOWT effectively prevented structural collapse and achieved a 14.7% reduction in peak hub displacement under coupled wind-earthquake loading. Furthermore, the peak residual drift of the PSCOWT remained below the threshold of the serviceability limit state.
