Power Quality Improvement in Distribution System by Cascaded Multilevel Inverter Based Statcom
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
In this paper, a simple static var compensating scheme using a cascaded two-level inverter-based multilevel inverter is proposed. The topology consists of two standard two-level inverters connected in cascade through open-end windings of a threephase transformer. The dc-link voltages of the inverters are regulated at different levels to obtain four-level operation. PI Control is employed for improving performance. Fuzzy control is employed to the system for deduction of THD. The dc-link voltages of the inverters are regulated at different levels to obtain four-level operation. The simulation study is carried out in MATLAB/SIMULINK to predict the performance of the proposed scheme.
