Unbalanced Faults in Series Compensated Transmission Lines

This paper presents a technique using the Gauss-Seidel iterative approach for the analysis of power systems which contain series compensated lines. This approach includes the effect of system dissymmetries due to a single unbalanced fault and due to a single or -two phase series capacitor short circuit caused by the excessive fault currents. Single phase to ground, two phases and two phase to ground fault studies of a series compensated power system are included.
