| Abstract: |
| To address the issue of insufficient utilization of voltage support potential and unsatisfactory autonomous voltage control of voltage source-based wind turbines based on DC capacitor voltage synchronization during low voltage ride-through, a voltage support strategy for voltage source-based direct-drive wind turbines based on active disturbance rejection control is proposed. The mechanisms of inertia synchronization and autonomous voltage support of voltage source-based wind turbines based on DC capacitor voltage synchronization are analyzed. Based on the power flow equations and the grid-connected structure of the voltage source-based wind turbine, the dominant factors influencing the voltage of common coupling point during fault are further analyzed. A first-order linear active disturbance rejection control voltage support strategy is then proposed, and a parameter setting method for linear active disturbance rejection control based on observer and controller bandwidths is presented. A grid-connected system for voltage source-based wind turbines with DC-capacitor-voltage-synchronization is constructed on the PSCAD/EMTDC simulation platform. Simulative results under various scenarios verify that the proposed method can effectively enhance the transient voltage support capability of the voltage source-based wind turbine. |
