REVIEW ON FUZZY LOGIC BASED POWER QUALITY IMPROVEMENT BY USING DSTATCOM BASED CASCADED MULTILEVEL INVERTER


Shankar Moguthala, R Senthil Kumar

Abstract: Power quality is a set of electrical boundaries that allows a piece of equipment to function in its intended manner without significant loss of performance or life expectancy. All electrical devices are prone to failure when exposed to one or more power quality problems. It is necessary for engineers, technicians, and system operators to become familiar with power quality. In this paper the solution is given by Static Compensator (STATCOM) with the desired reference current for Multilevel inverter based STATCOM for distribution system is employed. An investigation of multilevel inverter-based Distribution static compensator (D-STATCOM) with FLC in Power distribution System (PDS) for compensation of reactive power and harmonics mitigation. Cascaded H-bridge inverters having several advantages over conventional swathing devices are low harmonic distortion, reduced number of switches there by suppression of switching losses. The advantage of CHB Inverter is reducing the number of switches and thus switching losses. Hence in our paper we have proposed a DSTATCOM based Cascaded multilevel inverter by sing fuzzy logic controller to mitigate the switching losses, harmonics, and to compensate reactive power.
