In order to meet the high demand for power transmission capacity, some power companies have installed series
capacitor on power transmission line. The introduction of the capacitance in series with the line reactance allows reduction
in line impedance, thus resulting increased power transmission capability. It provides the benefits of increased system
capacity, reduced system losses and voltage regulation. The paper presents series compensated transmission line model by
using PSCAD. Results are tested with different fault locations for compensated and without compensated transmission line.
Performance of the developed method ensures that the proposed scheme gives the apparent effects when compensation is
going to be added in the line.
