The invention discloses a UPFC-based POD design method of a damping wind-power-system-included oscillating characteristic. The method comprises: S1, constructing a model of a unified power flow controller (UPFC); S2, constructing a model of a doubly-fed induction generator (DFIG) set; S3, adding the UPFC model obtained at the S1 and the DFIG model obtained at the S2 into a grid system; S4, analyzing influences on damping characteristics of a grid system by the wind-power grid-connected capacity and a UPFC compensation degree; S5, constructing a model of a damped oscillation controller (POD); S6, connecting an output terminal of the POD controller to a parallel side of the UPFC of the grid system in the S3 and using a signal of a grid system connecting line as an input signal of the POD controller; and S7, for the grid system in the S4, changing the output of a synchronous generator in the grid system and a transmission power of the grid system connecting line and analyzing influences on the damping characteristics of the grid system by the UPFC and the POD controller. Therefore, references are provided for large-scale wind power plant access planning and analyses of the power of the interconnection system connection line and inter-area oscillation characteristics.
