Abstract The Sub-Synchronous Control Interaction (SSCI) between the Doubly-Fed Induction Generator (DFIG) and the line series capacitance compensation is the main reason for the Sub-synchronous Oscillation (SSO) of the double-fed wind power grid-connected system. Among the control parameters, the proportional and integral parameters of the DFIG rotor side (RSC) current loop, the proportional and integral parameters of the grid-side converter (GSC) current loop, and the proportional and integral parameters of the phase-locked loop have influence on the system SSO characteristics. However, due to the difference in the magnitude of the parameters and the sensitivity changes with the parameter values, the traditional sensitivity calculation results have limitations. Therefore, the elastic coefficient and impedance analysis are combined to intuitively and accurately obtain the quantitative indicators of the influence of each control parameter on the stability of SSO. By adjusting the main influencing parameters and ignoring the secondary parameters, the control parameter adjustment method to suppress SSO is further developed. At the same time, an indirect adjustment method of the control parameters that takes into account the fundamental frequency characteristics of the doubly-fed fan is proposed. Finally, the correctness of the elasticity coefficient analysis and the effectiveness of the adjustment method are verified by time-domain simulation.
