Control Scheme for Stand-alone DFIG Feeding an Isolated Load

Abstract

This study addresses the control scheme of a standalone doubly fed induction generator (DFIG) feeding an isolated load. In order to control the voltage and frequency of the terminal bus, A direct voltage control is adopted. An instantaneous active and reactive component method is adopted in the proposed control strategy. Both the rotor and load side converter commands are built with the hysteresis controller according to the error between actual and reference currents. The simulation of stability performances analysis of 2 MW DFIG system is carried under Matlab/Simulink.
