D–STATCOM Based Multi-Level Inverter for Reactive Power Compensation
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
The line upgrading techniques with Static Synchronous Compensator (STATCOM) is one of the promising technologies applied to improve power system performance. The STATCOMs in the distribution utilities (DSTATCOMs) are increasingly investigated for dynamic reactive power compensation and power quality improvement in the distribution utilities. This paper presents an investigation of seven-Level Cascaded H - bridge (CHB) Inverter as Distribution Static Compensator (DSTATCOM) in Power System (PS) for compensation of reactive power and harmonics. The simplification and analyzing of three phase circuits can be done by d-q reference frame theory. The DST ATCOM helps to improve the power factor and eliminate the Total Harmonics Distortion (THD) drawn from a Non- Liner Diode Rectifier Load (NLDRL). Finally a level shifted PWM (LSPWM) and phase shifted PWM (PSPWM) techniques are adopted to investigate the performance of CHB Inverter. The results are obtained through Matlab / Simulink software package.
