Table 3 DSE performance variation, fault time of variation in θse at Vse = 5% of UPFC

From: A critical fault detection analysis & fault time in a UPFC transmission line

Type Of Fault in phase θse in deg. Fault Condition-1: 100 km from bus B-S(before UPFC) Rf = 1 Ω, FIA = 00 NSI, Vse = 5% Fault Condition-2: 300 km from Bus B-S (after UPFC) Rf = 1 Ω, FIA = 00,NSI, Vse = 5% Fault time in cycle
