Abstract—The IPFC (Interline Power Flow Controller) is among the FACTS devices aimed at simultaneously controlling the power flow in multiline systems. This paper presents the IPFC main features and limitations while controlling the power flow. In order to observe these advantages and disadvantages, a mathematical model based on the d-q orthogonal coordinates was developed. Issues like the relationship between the transmission angle and the IPFC controlled region as well as the converters operative region in steady-state will also be presented.. It is also used the real power being transferred between the compensated lines .For this purpose, 3 phase transmission line model associated with the converter station has been developed and incorporated in an IPFC model using SIMULINK . The results indicate that IPFC improves system reliability.

Index Terms—IPFC, reliability, transmission line, voltage source converter.
