<p>Commutation failure of high-voltage direct current transmission system integrated with wind farm can result in an alternating current system’s overvoltage issue, which seriously affects the safety of the power grid. By analyzing the formation mechanism of transient overvoltage caused by commutation failure, a multi-device coordinated control strategy is proposed. On the one hand, a wind turbine reactive power control optimization strategy is proposed based on the trigger angle of the rectifier station. On the other hand, a static var compensator branch control optimization strategy is proposed based on the variation rate of the trigger angle of the rectifier station. Finally, the case study shows that compared with the traditional control strategy, the proposed control strategy can effectively improve the reactive power absorption ability of wind turbines and reduce the static var compensator response delay, which presents a better transient overvoltage suppression effect.</p>
