The Interline Unified Power Flow, UPFC, IPFC are Voltage Source Converter (VSC) based Flexible AC Transmission System (FACTS) devices that can control active and reactive power flow in transmission line by means of injection controllable series voltage to the transmission line. This paper proposes a advanced connection for a Unified Power Flow Controller (UPFC) to improve the power flow control of one transmission line in a power system and it regulates bus voltage in another transmission line. It is connected between two different transmission lines, this type of connection of the UPFC will be called an interline UPFC (IUPFC). It is one of the advanced devices within the FACTS technology. The structure and principle Operation of IUPFC with 48-pulse GTO is discussed and its control scheme is based on the d-q orthogonal coordinates. The obtained simulation results from Matlab/Simulink confirm the effective features.
