Title:
WIND TURBINE GENERATOR SET, AND CONTROL METHOD AND APPARATUS FOR WIND POWER CONVERTER
Document Type and Number:
WIPO Patent Application WO/2023/108925
Kind Code:
A1
Abstract:
Provided in the present disclosure are a wind turbine generator set, and a control method and apparatus for a wind power converter. The control method comprises: 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; determining a phase angle of equivalent impedance of the wind power converter on the basis of the super-synchronous oscillation component of the grid-side voltage and the super-synchronous oscillation component of the grid-side current; and setting an operation mode of the wind power converter on the basis of 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.
