Abstract

GRID SIDE CONVERTER CONTROL IN DFIG BASED WIND SYSTEM USING ENHANCED HYSTERESIS CONTROLLER

Highlights

  • Over the past several years wind generation resource has been one of the significant renewable technologies with a rapid growth rate all over the world

  • The work presented in this paper extends and modifies the control techniques [11]-[14] and has been applied to a 15 kW doubly fed induction generator (DFIG) based Wind Energy Conversion System (WECS)

  • The proposed DFIG based WECS system has been simulated for a 15 KW, 380 V using MATLAB R2010a

Summary

INTRODUCTION

Over the past several years wind generation resource has been one of the significant renewable technologies with a rapid growth rate all over the world. A synchronization technique is developed for static delta modulated PWM inverters and the performance of the adaptive filter is presented in [11]-[12]. The latter eliminates the frequency modulation inherent in the delta modulated inverter as well as obtains balanced phase voltages. The work presented in this paper extends and modifies the control techniques [11]-[14] and has been applied to a 15 kW DFIG based WECS. The controllers developed can regulate the Vdc, obtain a wider range of GSC output voltage magnitude and enhance its power factor.
