Detection of Fault in Series Capacitor Compensated Double Circuit Transmission Line using Wavelet Transform

This paper presents wavelet transform based fault detection scheme for the protection of series capacitor compensated double circuit transmission lines. Three phase current of both circuits measured at relay location are used for the detection of fault. Three phase current of both circuits are processed using Daubechies-4 mother wavelet up to level-1. Performance of wavelet transform is tested for inter-circuit faults, cross-country faults, faults at boundary locations, fault resistance variation, ground resistance variation, fault inception time variation and fault location variation. Accuracy of wavelet transform scheme is 100%.
