Abstract： Doubly-fed asynchronous wind turbines have the advantages of good speed regulation performance and independent adjustment ofactive and reactive power，and have been widelyused in various large-scale wind farms， but in recent years，the sub-synchronous oscillation accidents of large-scale wind powerthrough series compensation and grid connection hasseriouslyafected the safetyand stabilityof the power system.At present，there are methodssuchaschanging theelectrical parameters，additional damping control，andadditional filtering devices to solve the problem ofsub-synchronous oscilltion，but thesuppression effect is poor due to the high-order，nonlinear，and strongly coupled characteristics of wind power generation systems.In order to solve the problem of subsynchronous oscilltion of doubly-fed wind turbines，an optimal suppresion strategy with additional damping controllr is proposed in the RSC control system.By modeling and conducting simulation experiments on MATLAB/

Simulink，the feasibilityand superiorityof the scheme wereverified，and theamplitude suppresionrateof subsynchronous oscillation reaches 83.16%
