Abstract: This paper presents the systematic procedure of the modeling and simulation of a Distribution STATCOM (D-STATCOM) for power quality problems & maintain the voltage profile based on Sinusoidal Pulse Width Modulation (SPWM) technique. It also explains the problems that are due to poor Power Quality in electrical systems. In this case, injection of harmonics from power electronics devices into the system also caused some problems which were later overcome by using SATCOM and RLC filters. The obtained results show that STATCOM is very efficient and effective for maintain the voltage profile. It is shown that by using the right technology a variety of Power Quality problems can be solved rendering installations trouble free and more efficient. The major problems dealt here is the voltage sag and swell. To solve this problem, custom power devices are used. One of those devices is the Distribution STATCOM (D-STATCOM), which is the most efficient and effective modern custom power device used in power distribution networks. D-STATCOM injects a current in to the system to correct the voltage sag and swell. STATCOM is one of the key as shunt controllers in flexible alternating current transmission system (FACTS) to control the transmission line voltage and can be used to enhance the load ability of transmission line and extend the voltage stability margin. The control of the Voltage Source Converter (VSC) is done with the help of SPWM. The proposed D-STATCOM is modeled and simulated using MATLAB/SIMULINK software.
