AbstractAbstractA new distance-relaying algorithm for single-phase-to-ground faults on series-compensated parallel transmission lines is proposed in this article. Fault impedance can be calculated using this algorithm without any parameters requirement of mutual coupling and series capacitor device (series capacitor/metal oxide arrestor/discharging gap). The series capacitor device is simplified as linearized impedance during faults. The parameters of mutual coupling and a series capacitor device can be used as variables in the fault loop equations. Real-time digital simulator tests show that the proposed distance-relaying algorithm can obtain more accurate results than traditional distance-relaying algorithms for series-compensated parallel transmission lines.Keywords: distance relayseries-compensated parallel linesmutual couplingseries compensatedcapacitormetal oxide arrestor Additional informationNotes on contributorsZhenyu XuZhenyu Xu received the Ph.D. degree in electrical engineering from North China Electric Power University (NCEPU), Beijing, China.
