Title:
CONTROL METHOD AND CONTROL APPARATUS FOR VOLTAGE-SOURCE-TYPE WIND TURBINE GENERATOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/108926
Kind Code:
A1
Abstract:
Provided in the present disclosure are a control method and control apparatus for a voltage-source-type wind turbine generator system. The control method comprises: determining a virtual angular frequency deviation by means of a virtual inertia damping link, wherein parameters of the virtual inertia damping link are determined on the basis of a moment of inertia and a damping coefficient of a wind turbine generator of a wind turbine generator system; determining a virtual inner potential phase; determining a d-axis component and a q-axis component of a modulation voltage; and controlling a grid-side converter of the wind turbine generator system, so as to adjust an injection voltage of a grid-connected point of the wind turbine generator system.
