Series Compensation of an Uprated 230 kV – 50 Hz Backbone in Central Italy: Impact on Fault Quantities
The predominant reason for adding series capacitors in power systems is to increase power transfer capacity enhancing both the voltage and angle stability margins. The resulting decrease in series reactance can determine also undesired effects during faults: the fault current increases in dependence of the compensation degree and of the fault location in the system. This paper investigates the case of an Italian 230
