Various types of Wind Generator Systems and Their Comparisons

Abstract

Considering the increasing share of wind generation interfaced to grid it is necessary to study the power quality and reactive power issues considering voltage quality and stability issues. In case of Induction type wind energy converter reactive power management in cost effective way is essential. In many wind farm wind energy converter using Synchronous generator and Induction generator are used. Use of Synchronous generator leads to distortion of wave shape and are sensitive to grid disturbances. Considering the challenges to be faced related to interfacing of large wind farms using Induction and Synchronous generators, it is necessary to study the different wind generator systems and their comparisons. The wind energy conversion system is demanded to be more cost competitive, so that comparisons of different wind generator systems are necessary. An overview of different wind generator systems and their comparisons are presented. Also Critical Power Quality issues & Problems related with Grid connections are also discussed.
