Wind power system based on Squirrel Cage Induction Generator

This work presents a study of the wind power system based on Squirrel Cage Induction Generator (SCIG). It also presents an analysis of voltage regulation at the point of common connection (PCC). The induction machine is connected to the grid through a back-to-back PWM controlled voltage source converters (VSC). The induction generator side converter controller (IGSC) is based on field oriented control, while AC side converter controller (ACSC) is based on instantaneous power theory. A 5 hp experimental prototype was developed in Power Electronics Laboratory at COPPE / UFRJ. This prototype will be used to validate the simulated model developed in PSCAD / EMTDC and control strategies.
