Abstract:

One of the main areas of concern in the transmission and distribution systems during the past forty years has been power quality. Voltage sag, voltage swell, harmonics, voltage fluctuation, etc. are the main system faults. To address such issues, a variety of bespoke power devices are used. The multi-level inverter-based DVR used to safeguard delicate equipment like computers and printers from line faults such voltage sag is covered in this essay. The multilevel inverter topology provides the foundation for the DVR's deployment in the distribution system's defense against voltage sag. The system serves as the single phase 230V power distribution system. This paper illustrates a multi-level inverter-based DVR system using Simulink. . The multilayer inverter can more effectively correct the voltage sag problem and enhance voltage quality, according to all results displayed in the MATLAB software.
