Abstract

Grid is the interconnection of power injection and consumption. This grid suffers by deficient of reactive power and its quality of power supply. This quality is improved by injecting reactive power by a FACTS device, STATCOM. STATCOM is a reactive power controller device based on the requirement it will inject or absorbs reactive power from the grid. The performance of STATCOM is improved by closed loop control system. The power quality is measured by THD (Total Harmonic Distortion). Compared to open loop it improves power quality by minimizing THD, improving power factor and RMS voltage of the grid. The simulation is carried out using MATLAB software, various graphs and numerical results are presented to prove the ability of closed loop STATCOM in the grid connected power system
