A wind turbine generator set, and a control method and apparatus for a wind power converter are provided. The control method includes extracting a super-synchronous oscillation component of a grid-side voltage of a wind power converter and a super-synchronous oscillation component of a grid-side current of the wind power converter. The control method also includes determining a phase angle of equivalent impedance of the wind power converter based on the super-synchronous oscillation component of the grid-side voltage and the super-synchronous oscillation component of the grid-side current. The control method further includes setting an operation mode of the wind power converter based on the super-synchronous oscillation component of the grid-side voltage and/or the super-synchronous oscillation component of the grid-side current, and the phase angle.

The present application provides a method and a system for controlling continuous low voltage ride-through and high voltage ride-through of a permanent magnet direct-driven wind turbine. The method includes: determining a transient time period during which the wind turbine is transitioned from a low voltage ride-through state to a high voltage ride-through state; controlling the wind turbine to provide, during the transient time period, a gradually increasing active current to the point of common coupling; and controlling the wind turbine to provide, during the transient time period, a reactive current to the point of common coupling according to an operation state of the wind turbine before the low voltage ride-through state.
