Two-Level Inverter Based STATCOM for High Power Applications with PQ controller

Abstract

Flexible Alternatin Current Transmission System (FACTS) technology opens up new opportunities for controlling power and enhancing the usable capacity of present, as well as new and upgraded lines. This second generation FACTS device which enables independent control of active and reactive power besides   improving   reliability   and   quality   of   the supply. This paper describes the real and reactive power flow control through a transmission line by placing the series and shunt converter at the sending end of an electrical power transmission system. Simulations are carried out in Matlab/Simulink environment to validate the performance.
