This paper describes closed loop controlled inter Line Power flow controller used in power system. An Inter line power flow controller is VSC-based FACTS controller for series compensation with the unique capability of power management among multilines of a subs-station. The FACTS technology is essential to alleviate these difficulties by enabling utilities to get most service from their transmission facilities. FACTS controllers can control series impendence, shunt impedance, current, voltage and phase angle. Different FACTS controller’s circuits are simulated using PSPICE software package.IPFC is used to improve the power flow and to provide a power balance of a transmission system. The circuit model of IPFC was developed and the same is used for simulation.

Key Words FACTS, SSSC, IPFC, TCR, PSPICE.
