Impact of Inertia Control of DFIG-Based WT on Torsional Vibration in Drivetrain

As wind power reaches a high penetration in power systems, inertia control is required in grid codes to improve the system frequency dynamics. This supplemental control will couple the mechanical system of wind turbines (WTs) with the electrical system, causing torsional vibration in drivetrains. However, the impact of inertia control on this torsional vibration can be rarely seen in literature. This article studies the mechanism of this impact and the impact rule of different parameters. A small-signal model of a DFIG-based WT with inertia control is first proposed to study the interaction between the inertia control and WT's torsional vibration. The differences between controls in DFIG-based WTs are considered in this model. Through the model, interaction paths can be obtained to help explain the impact mechanism from a general perspective. On the basis of analyzing the interaction paths, the impact rules of different parameters on the damping of torsional vibration in drivetrain are investigated in detail. Finally, time-domain simulations are performed to demonstrate the correctness of the analyses.
