This paper presents simulator demonstration of fault current limitation based on the Thyristor controlled Interphase Power Controller (IPC) technology. From a power system point of view, this TC-IPC has the same function as a transformer: it handles its share of the load current but, during a fault, it does not contribute to the fault current. It thus allows a substation to be uprated without increasing the fault level. A 25 kV substation is used to illustrate the concept. In this paper simulation results are obtained using Matlab Simulink in order to show the performance of TC-IPC when fault occurs in an one bus in IEEE 30 bus systems.
