Abstract :

Improved Unified power flow controller (IUPFC) is a unique type which is able to regulate power system parameters such as active and reactive power along with voltage magnitude and phase angle is presented based on Flexible AC transmission (FACTS).By Injecting controllable voltage in series to transmission lines, reactive and active power can be controlled. The IUPFC is a combination of a static synchronous compensator (STATCOM) and a static synchronous series compensator (SSSC) coupled via a common DC voltage link. IUPFC 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 IUPFC using a 48-pulse controller i.e., static synchronous series compensator (SSSC),Improved unified power flow controller (IUPFC), and static synchronous compensator (STATCOM). STATCOM, SSSC, and IUPFC are designed to stabilize voltage and provide compensation to reactive power of the power grid system, by using a 48-pulse converter. This paper envelops a innovative approach based on voltage source converter is used for the designing of detailed model of GTO based UPFC is implemented in Mat lab/SIMULINK.
