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 | ||||
