Power quality improvement by using DSTATCOM

Distribution system, as the name suggest, is the medium through which power is distributed among the end consumers. Distribution systems are comparatively not as stiff as grid systems, so objectionable voltage drop due to the increase of RL load could be critical for the entire system. Thus DSTATCOM is an effective solution for power systems facing such power quality problems.\ud This report deals with one of the potential applications of distribution static compensator (DSTATCOM) to industrial systems for mitigation of voltage sag problem.\ud The model of DSTATCOM connected in shunt configuration to a three phase source feeding RL loads is developed using Simulink of MATLAB software. Simulated results demonstrate that DSTATCOM can be considered as a viable solution for solving such voltage dip problems. This thesis work aims at developing a DSTATCOM for inductive and resistive loads with reduced voltage sag
