The invention relates to a high voltage ride-through method of a wind power converter. The wind power converter comprises a direct-current bus voltage bleeder circuit. The direct-current bus voltage bleeder circuit comprises an IGBT and a direct-current unloading resistor, and the IGBT and the direct-current unloading resistor are connected to the two ends of the converter after being connected in series. When the voltage of a power grid is higher than a set multiple of nominal voltage, the high voltage ride-through state is started, reactive output of a grid side converter is increased, the transient transition process of high voltage ride-through is achieved, and a unit can ride through a fault at the power grid voltage of 1.1 pu to 1.3 pu. Meanwhile, the fluctuation of the active power of the converter can be suppressed through positive and negative sequence current control, the direct-current bus voltage bleeder circuit releases electric energy, and the fluctuation of the active power of grid connection and the direct-current bus voltage caused by unbalance of the electrodynamic potential of the power grid can be effectively suppressed.
