Abstract: The present disclosure provides a wind turbine, a converter, and a low-voltage ride-through detection method and device. The low-voltage ride-through detection method includes: determining an adjustment value of a preset parameter of a power grid on the basis of a power grid voltage, wherein the preset parameter includes at least one of a current, a current frequency and a power factor angle; adjusting the preset parameter of the power grid on the basis of the adjustment value; and detecting, on the basis of a power grid voltage after the preset parameter of the power grid is adjusted, whether the power grid meets a low-voltage ride-through condition. Therefore, a power grid fault of the wind turbine in a weak grid can be accurately identified, so as to enter a low-voltage ride-through state, thereby avoiding system instability in the process of a power grid fault ride-through in the weak grid.
