Abstract

Under external disturbance, the shafting oscillation with weak/negative-damping generally occurs in grid-connected doubly-fed induction generator （DFIG）-based wind power generation system, which may lead to the low-frequency oscillation in the connected power grid and weaken the dynamic stability of the DFIG system and the power system. For improving the shafting oscillation damping of the grid-connected DFIG-based wind power conversion system, this paper designs two suppression control strategies of shafting oscillation implemented in RSC （rotor side converter） power control sections, which is based on the motivation mechanism of the DFIG electromagnetic torque on the shafting oscillation damping and the characteristics of the generation and transfer for the torque and active power in the DFIG-based wind power generation system. Furthermore, the effectiveness of the proposed control strategies is verified by the simulation results on DIgSILENT/PowerFactory. The results show that the two control strategies can significantly enhance the damping of the shafting oscillation, which promotes shafting dynamic characteristics under MPPT （maximum power point tracking） operation mode and constant power control mode respectively.
