PWM Techniques to Power Converters of the Wind Energy Conversion System

Abstract

the modern type-3 wind energy conversion system consists of wind turbine, doubly fed induction generator and advanced AC/DC/AC power converters connected to the grid. To study the dynamic issues of the wind energy conversion system the dynamic model is necessary. To perform the stability analysis of the grid connected with the use of back to back converter, the various power converter topologies used in grid integration of are to be known. This paper presents the detailed study on sinusoidal pulse width modulation and space vector modulation techniques, its basic operation, circuit design, configurations and overview of control structure of the back to back converter applicable for wind power conversion systems.
