Voltage swells after grid fault clearance is one of the major causes of large‐scale wind power tripping accidents in China. In this study, reasons that led to overvoltage phenomena were researched, and factors that influence the grid overvoltage during grid fault were quantitatively analysed through simulation. A coordinated reactive power control strategy combined the control of wind turbines with reactive power compensation devices was proposed to prevent the occurrence of high voltage and improve the high‐voltage ride through capability of wind power plant. Finally, the effectiveness of the proposed control strategy was indicated by the simulation results in DIgSILENT/PowerFactory.
