Investigation of cascaded H-Bridge multilevel Inverter as Distribution Static Compensator in Power System for compensation of reactive power and harmonics

Abstract

An Inspection of Multi-Level H - bridge Inverter is used in a Distribution Static Compensator (DSTATCOM) in Power System (PS). By using the multi-level inverter we will get the advantage of low harmonic distortion, less number of switches to achieve the multi-level output over the traditional inverter with less switching losses. With respect to improve power factor, we need to compensate the Reactive power and overcome the total harmonic distortion (THD) drawn from Nonlinear Load. We will come up with Level Shift Pulse Width Modulation (LSPWM) technique to control the switches of Inverter And for the generation of reference current for DSTATCOM we will use P-Q theory. This advance system is simulated MATLAB and Results are Discussed.
