Investigation of Multi Phase Power Transmission System With Thyristor Controlled Series Capacitor

Abstract: Multi-phase transmission systems is considered potential alternative to conventional three-phase systems for bulk power transmission. Recent survey shows that the integration of flexible A.C. transmission system devices into conventional three-phase transmission system for enhancement and control of power flow is well established. This paper attempts to study: a FACTS device i.e. thyristor controlled series capacitor (TCSC), its model and effect on power flow and load ability of multi-phase transmission lines. Sample systems are used to study quantitative benefits of four-phase and twelve-phase lines.
