F. Beauregard et al., THE IPC TECHNOLOGY - A NEW APPROACH FOR SUBSTATION UPRATING WITH PASSIVE SHORT-CIRCUIT LIMITATION, IEEE transactions on power delivery, 13(1), 1998, pp. 233-240
The paper presents a new approach to fault current Limitation based on
the Interphase Power Controller (IPC) technology. From a power system
point of view, this TPC has the same function as a transformer: it ha
ndles its share of the load current but, during a fault, it does not c
ontribute to the fault current. It thus allows a substation to be upra
ted without increasing the fault level. A four-transformer 315-120 kV
substation is used to illustrate the concept.
