Aiming at the problem of wind turbine off-grid due to lack of high voltage ride through (HVRT) capability of wind power, the internal mechanism of wind turbine off-grid due to voltage increase of junction point caused by DC fault is elaborated. The dynamic reactive power response characteristics of energy storage system and static var generator (SVG) during HVRT are analyzed. Through real-time monitoring of the voltage of the junction point, the priority of the control strategy during HVRT crossing is divided into reactive power regulation inside the wind farm (cooperative control of energy storage system and doubly fed induction generator (DFIG)) and SVG reactive power regulation. On this basis, a collaborative control strategy of energy storage system, DFIG and SVG is proposed to improve the HVRT capability of wind farms. At the same time, the voltage reference value for adverse situations after fault removal is reset to avoid unnecessary reactive power flow. Finally, a simulation model is built based on MATLAB/Simulink platform to verify the correctness and effectiveness of the theoretical analysis and control strategy. The research results provide new ideas for fully exploring the reactive power regulation capability of wind farms and greatly reducing the burden of SVG reactive power compensation.
