This paper introduced the design method of supplementary damping controller of DFIG with the mode-based damping torque analysis method. Firstly, the principle of the mode-based damping torque analysis method is stated. Then, the comparison of the mode-based damping torque analysis method and two traditional controller design methods, that is, the classical damping torque analysis method and the residue method, are illustrated. Through theoretical derivation, it can be seen that different from the classical damping torque analysis method, the mode-based damping torque analysis method takes the oscillation mode of the power system as the main analysis object directly, which reduced the amount of calculation greatly. In addition, in the controller parameter adjustment in closed-loop system, the “dynamic” mode-based damping torque indicator is theoretically more accurate than the “static” residual indicator. Finally, the modified two-area four-machine power system is used to determine the installation location and parameters of the supplementary damping controller of DFIG with the model-based damping torque analysis method, which demonstrated the correctness of the method.
