Development of a method for selective determination of the outgoing line and the distance to the place of occurrence of a single-phase earth fault

Abstract

Subject of research: algorithms for selective determination of the outgoing line in the event of a single-phase earth fault; algorithms for determining the distance to the fault location.
 Purpose of research: development of an industrial frequency overlay method for determining the outgoing line with a single-phase earth fault. Development of an algorithm for determining the distance to the place of a single-phase earth fault by the method of standing waves.
 Object of research: electrical networks 6-35 kV.
 Methods of research: theory of electrical circuits, mathematical analysis and modeling; resonant modes; standing wave method.
 Main results of research: An algorithm for the selective determination of the outgoing line with a single-phase earth fault has been developed. An algorithm for determining the distance to the closure site by the standing wave method has been developed.
