In Power System, there are several problems cause of overloading issues, dangerous blackouts, voltage fluctuations, and collapse. A system's voltage profile will be better as a result of improved reactive power compensation, raising the system's overall power quality. In this paper, the power quality analysis examined case study i.e. Standard IEEE 9 bus system describes the During-fault, and Post-fault conditions using DSTATCOM device carried out with MATLAB software. The pre-fault condition is accomplished using the power flow study by the Newton-Raphson method, and the influence of a three-phase balanced fault has been deliberated during-fault conditions. The IEEE-9 bus system was first examined using standard test data, and subsequently the same system was examined using D-STATCOM. The system's reactive power compensation, voltage profile, and line losses with and without D-STATCOM are all investigated.Also this paper presents a comparative analysis of IEEE 9 bus system power quality analysis using D-STATCOM device with respect to without DSTATCOM device to improve system performance.
