Title:
ALLOCATING REACTIVE POWER PRODUCTION FOR DOUBLY FED INDUCTION GENERATOR WIND TURBINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/010120
Kind Code:
A3
Abstract:
Systems and methods for allocating reactive power production in a doubly -fed induction generator (DFIG) wind turbine system including a DFIG and a power converter including a line side converter and a rotor side converter are provided. A method can include obtaining a reactive power production requirement, obtaining one or more operating parameters for the DFIG and the line side converter, and determining a priority ratio based at least in part on the one or more operating parameters. The priority ratio can be a ratio of reactive power production between the DFIG and the line side converter. The method can further include controlling the DFIG and the line side converter based at least in part on the reactive power production requirement and the priority ratio such that the combined reactive power production from the DFIG and the line side converter meet the reactive power production requirement.
