Implementating a Linear Controller of STATCOM Design in DC Link Voltage

Abstract

Power demand is increasing day by day, the new generation requires enough of resources, time period and budget allocation, and it is observed in the transmission system the percentage of power is wasted in the form of loss, and these is especially due to reactive power, by proper compensation of the reactive power through a FACTS device, known as statcom, the power can be effectively transmitted and can meet the demand. This project describes the modeling of statcom along with the design of Linear Controllers, even though the statcom is a nonlinear device due to its complexity in mathematical modeling, design of controllers for the converters is done by linear method with the linear controller and the method is adopted and simulated waveforms are presented. The designed controllers with variation of DC link voltage have been applied to the compensator. All responses are obtained through MATLAB SIMULINK tool box.
