Majority of the consumer loads are of non-linear in nature and bring about deprived quality of power in distribution system. FACTS based DSTATCOM is a compensating device placed in shunt to power line to improve the power quality eliminating the effect of harmonics in source components. The paper presents multi-level DSTATCOM in distribution system to enrich the quality of power. Five-level cascaded H-Bridge structures DSTATCOM is employed to drive with compensating signals for power quality improvement. Five-level DSTATCOM is triggered from multi-carrier LSCPWM pattern. Reference signals are generated from IRP based control theory. The proposed system is capable to compensate for system unbalance, power factor and harmonics in the system. Simulation work of the proposed concept is carried out and the results are presented using MATLAB/SIMULINK software.
