Abstract
To improve the efficiency of existing transmission lines, Smart Power Flow controlled (SPFC) is presented based on Flexible AC transmission (FACTS). By Injecting controllable voltage in series to transmission lines, reactive and active power can be controlled. SPFC helps the transmission lines to obtain their maximum power capacity by avoiding the redundant reactive power which overloads the transmission line. This paper investigates three different modes of SPFC using a 48-pulse controller i.e., static synchronous series compensator (SSSC), unified power flow controller (UPFC), and static synchronous compensator (STATCOM). STATCOM, SSSC, and UPFC are designed to stabilize voltage and provide compensation to reactive power of the power grid system, by using a 48-pulse converter. Using 48-pulse STATCOM reduces harmonics and gives the maximum power at 90 degrees of injected voltage in SSSC. The overall SPFC has been investigated and simulated in MATLAB/SIMULINK environment.
