An Advanced DPC-Self Excited Induction Generator Drive Scheme for an Isolated Wind Turbine Boost System

Abstract – In this paper, the Authors present a Direct Power Control scheme of an Induction Generator (IG) associated with a wind turbine system. The turbine is used to drive the IG in order to feed an isolated DC load. It receives the required active power from the generator through a rectifier, DC bus and a boost converter. The models of the system components are developed and used in the system control scheme. Mathematical relations treating the system components are presented and studied. The generator and the turbine dynamic performances are analyzed. The simulation results of the system entire control have shown that the proposed methodology is an efficient and promising control procedure.
