Modeling studies of inter line power flow controller for multi line transmission system

This paper describes inter line power flow controller 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 multiline´s of a substation. 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 impedance, shunt impedance, current, voltage and phase angle. The different controller´s circuits are simulated using PSPICE software package. IPFC 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.
