Abstract
Distribution systems with three-phase three-wire, four-wires face several power quality issues, including a high burden of reactive power, load imbalances, poor voltage regulation, and in four wire system there is an excessive neutral current. Several customized power devices are recommended to mitigate power quality issues that may develop in the system. A distribution static compensator is used to compensate for power quality concerns on distribution side. The research focuses on the application of DSTATCOM. This article describes how to use an synchronous reference frame (SRFT) to design a Nonlinear load pose power quality issues; hence, a Distribution static compensator is needed for compensation for three wire and four wire distribution system. The proposed SRFT approach is utilized to extract the current components required for creating a voltage source converter (VSC) reference signal. The DSTATCOM employs this technique to remove harmonics, reactive power from the three-phase distribution system. MATLAB is used to design and build the entire system. The simulation results suggest that the methodology is effective in correcting for PQ issues.
