Due to growing complexity in the power system, voltage sag becoming one of the most significant power quality disturbances. Voltage sag is a short-duration reduction in RMS voltage caused by faults on the power system and the starting of large loads, such as motors. If voltage sags exceeds, then industrial units making use of sensitive electronic equipments are likely to be affected with major problems. This issues sometimes leads to ruin of resources like material and human as well as financial losses. This paper discusses about the Power quality improvement in non- linear distribution system using a D-STATCOM with a superconducting magnetic energy storage (SMES) as its source. Progress in both superconducting technologies and power electronics led to SMES systems having some tremendous performances particularly for use in power systems. DSTATCOM includes a Voltage Source converter and a DC link capacitor or source connected in shunt, capable of generating or absorbing reactive power. The proposed system allows the compensation of current harmonics and unbalances, and can be a much better solution than the conventional approach. This proposed system is analyzed and simulated using MATLAB/SIMULINK.
