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, hybrid series compensators composed of SSSC (static synchronous series compensator) and fixed capacitor are utilised, and a method of supplementary damping control for the converter is proposed in this paper. The position of the converter controller to impose the supplementary damping signal is chosen at first, then supplementary damping control and its principle to damp SSO is presented as well. Finally, time‐domain simulations are performed to analyse and verify the SSO damping effectiveness of the designed supplementary damping control. Meanwhile, the simulation results also suggest that the designed supplementary damping control has no negative effect on the performance of the hybrid series compensator.
