POWER QUALITY ENHANCEMENT USING 7 LEVEL CASCADED H - BRIDGE INVERTER BASED D - STATCOM WITH PQ THEOR Y
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
This paper presents an investigation of Seven - Level H – bridge Inverter is used in a Distribution Static Compensator (DSTATCOM) in Power System (PS), making use of seven level cascaded inverter benefits of low harmonics distortion, reduced number of switches to achieve the seven - level inverter output over the conventional cascaded seven level inverter and reduced switching losses . In order to improve the power factor, compensate the reactive power and suppress the total harmonics distortion (THD) drawn from a Non - Liner Diode Rectifier Load (NLDRL) of DSTATCOM, we propose a Level Shift Pulse Width Modulation (LSPWM) technique is used as control for the switches of H – bridge Inverter. The PQ theory is used to generate the reference compensating current for DSTATCOM . The proposed system is simulated in the MATLAB environment using simulink and results are discussed
