Abstract Frequency drift is the significant feature of subsynchronous oscillation in wind turbine generator intergrated power system. The paper examined the frequency drift from the perspective of modal interaction affected by the variation of wind speed. First, two subsynchronous oscillation modes of wind turbine generator affected by wind speed were presented. One is the oscillation mode dominated by the stator and rotor windings and rotor-side converter current inner control loop of doubly-fed induction generator and its frequency depends on the wind speed. The other is the oscillation mode dominated by the DC voltage outer loop of direct-drive permanent magnetic synchronous generator and its residue is affected by the wind speed. Then, open-loop modal coupling condition was derived to reveal the mechanism of strong interaction between two oscillation modes of double-input double-output system. Finally, based on a doubly-fed induction generator intergrated series compensated power system and a wind farm intergrated power system, modal analysis and nonlinear simulation were adopted to demonstrate the frequency drift caused by the change of the degree of modal interaciton with the variation of wind speed. The main conclusion of this paper is that the randomness of wind speed makes the open-loop modal coupling condition random and the adverse interaction between oscillation modes in time-varying scenarios makes the frequency of the weakly or negatively damped subsynchronous oscillation mode change dynamically, thus the phenomenon of frequency drift appears.

Key words： Doubly-fed induction generator direct-drive permanent magnetic synchronous generator subsynchronous oscillation frequency drift modal interaction
