STATCOM Controller Design and Experimental Investigation for Wind Generation System

Abstract

Controlling of Wind Generation System (WGS) is a vital process to adjust the value of voltage fluctuation that linked to the grid under variations of wind speed. In this paper, a variable speed wind-Turbine unit coupled with permanent-magnet synchronous generator is modeled. STATCOM-control methodologies are established on the basis of two controllers; PI controller and Self-Tuning Fuzzy Logic PI-Controller (STFPC). Laboratory model of the WGS using DC motor with an armature current control is designed to achieve a real time simulation of the system. The results are evidenced on the validation of the suggested controlling methodologies. The paper presents experimental comparisons of STFPC with PI-controller. Also, the superiority of utilizing STFPC over PI-controller has been proven.
