摘要：
A coordinated control strategy is proposed for the LVRT (Low Voltage Ride Through) of wind farm with grid-connecting VSC-HVDC. The models for HVDC line and wind farm are built and the working principle of system during grid fault is analyzed. The converters at both sides of HVDC provide reactive power during LVRT and the fast power reduction based on voltage control is adopted to control the in-feed power of wind farm for the power balance of DC system. The hierarchical control is coordinated with the HVDC control to improve the power control of wind turbine for its voltage stability. The simulative results of case study verify the quickness and effectiveness of the proposed control strategy.
