摘要：
Damping is the core factor affecting the drive-train torsional oscillation of the doubly-fed induction generator (DFIG). According to the Grid-Connected Guidelines, wind power is supposed to participate in frequency modulation. The shaft system's torsional oscillation damping characteristics may become more complicated when the DFIG contains virtual inertia control. First, the torsional oscillation damping characteristics of the DFIG under the maximum power tracking control are analyzed when adopting the damping torque method in this paper. On the basis, the electromagnetic-torque-generator- speed loop transfer function of the DFIG is derived after the virtual inertia control is introduced, which illustrates why the torsional oscillation damping is reduced. Secondly, the torsional oscillation frequency deviation caused by Bandpass-Filter and Phase-Compensation Based Torsional Damping Controller (BPB-TODC) attached to different power channels is analyzed. Aiming at the problem that the torsional oscillation frequency deviation degrades the performance of the damping controller based on the duel-channel BPB-TODC, this paper proposes the anti-torsional vibration frequency deviation by optimizing the controller parameters in the multiple torsional frequency deviation scenario. Finally, simulations verify the correctness of the theoretical analysis and the effectiveness of the proposed damping controller. © 2021, Power System Technology Press. All right reserved.
