Abstract:In order to investigate the influence of doubly fed induction generator (DFIG) on power system damping, the conception of frequency-power dynamic characteristic for generic component is presented in this paper. Based on the proposed conception, two propositions are proved to be available for examining the damping of generic component. The phase of frequency-power dynamic characteristic of generic component can tell whether the damping performance is positive or not, and its magnitude can tell how strong the damping is. Because the DFIG is one of the generic components, the proposed definitions and propositions in this paper are useful for analyzing the impact of DFIG on power systems. Through a simulation case, both frequency-power dynamic characteristic and influence of damping contribution are analyzed under different regulator parameters of DFIG. So, the practicability of the proposed definitions and propositions is further validated.
