Wind Turbines Based on Doubly Fed Induction Generator in Coordinate Operation with a STATCOM

Abstract

This paper approach the study of Doubly-Fed Induction Generators (DFIG) next to the device FACTS (STATCOM), connected directly on the bus CA transmission line. The DFIG, in your structure, is composed for two converters of the type back-to-back, these responsible by control the voltage at the DC link and the power flows in the network. Through a STATCOM and the use technical control based on pq Theory, there are at system the bracket voltage control on the bus CA on which the DFIG is connected. This work will address the voltage regulation at PCC (common connection point) in case of disturbances on system. Simulation Results, utilizing the computational tool PSCAD/EMTCD, are submitted to prove effectiveness the use of STATCOM at the proposed system.
