Power Quality Improvement Using DSTATCOM For IEEE 9 Bus System

Abstract

The rapid rise of people is causing  significant issues in the electricity system by increasing  energy consumption or load demand. 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.
