Multiple Windturbine Interfacing Using Fuzzy Logic for a Pwm Current Source–based Dc Transmission System

This project mainly deals with the study of obtained output power by interfacing multiple wind turbine by using pulse width modulation(PWM) current source wind energy conversion system based on a parallel configuration. This has some of the advantages of the VSC based system, but is inherently robust to both dc and acshort circuit faults. Furthermore, this configuration overcomes some disadvantages of a current source based series connected system. Where, it effectively controls the average dc–link voltage with a feed forward loop. While independently controlling the reactive power.Using fuzzy logic will additionally help in reducing the reactive power and improves the overall efficiency by the reduction ofTotal Harmonic Distortion(THD). A study on series and parallel configuration is done and parallel configuration is preferred for the proposed system for its merits.
