Abstract

With the widespread applications of series compensated capacitors for wind farm integration

some DFIG（doubly fed induction generator）based wind farms are confronting with severe problem of SSO（subsynchronous oscillation）.To solve the SSO problem of DFIG based wind farms

hybrid series compensators composed of SSSC（static synchronous series compensator） and fixed capacitor are utilized to integrate the wind farm

and a novel method of supplementary damping control for the converter is proposed to mitigate SSO in this paper.Finally

time domain simulations are performed to verify the SSO damping effectiveness of the designed supplementary damping control.Meanwhile

the simulation results also suggest that the designed supplementary damping control has none negative effect on the performance of the hybrid series compensator.The studies in this paper are supposed to be helpful for the design of the wind farm integration projects and the mitigation of the SSO problem.
