Power flow management in multiline transmission system through reactive power compensation using IPFC

Abstract

Interline Power Flow Controller (IPFC) is a series–series type of device belongs to FACTS family. The main purpose of using IPFC instead of remaining FACTS devices is that it can provide series compensation for a required transmission line in system, and also IPFC can control power flow across different lines simultaneously in system. In actual IPFC is a combination of two Voltage Source Converters (VSC’s) connected in series by a common dc link in between. By compensating particular line in transmission system, the power flow management becomes effective. It can also possible to exchange reactive power through series compensation within the transmission system. The Voltage Source Converters makes use of snubber capacitance and resistance for reactive power compensation. In this paper a three-phase system is simulated and analyzed by connecting with IPFC Results of the proposed system with output as reactive power are verified for a particular line with and without IPFC.
