Abstract :
Increase in demand and ever-increasing expansion of interconnected power networks lead to increase in short circuit levels higher than interrupting rating of power circuit breakers and other pertinent equipments. In planned expansion of Iran Electric Power Network (IEPN) for 2014, a few substations in Tehran Regional Electric Company have been experiencing the over mentioned problem for long time. In this study, parameters design as well as IPC capabilities in limiting fault current in Tehran 230 kV and 400 kV power substations with optimal localization have been discussed. All simulations were carried out utilizing DigSilent software package. Results show that optimum localization of Interphase Power Controller can lead to limit fault current level down to nominal interrupting level of circuit breakers in many substations of Tehran transmission power network.
