Fault location in distribution network using cumulative approach

Abstract

In distribution system, the subject of fault location has been of considerable interest for a long time. The objective of this paper is to develop Cumulative approach for fault location based on statuses of Fault Indicators (FI), Circuit Breakers (CB), Fuses and Fault Impedances from distance protection devices. This approach is using mainly graph theory algorithms and Area Marking Strategy to resolve fault diagnosis problem in electric power networks. Unlike neighborhood approach where one link only affects the marking of neighbor areas, cumulative approach marks all areas down the link. In many situations, cumulative approach may out-perform neighbor approach.

Software package for power system analysis

“…Also modeling of large and complex networks by the means of classes can be quite stressful and time consuming. PSA is developed to provide fast and accurate simulation, calculation, and optimization of distribution network states through state estimation [22], distribution power flow [14]- [16], optimal feeder reconfiguration, fault location and analysis [23], [24], and voltage-var control [25]. It offers clear and simple, fully graphical user interface with possibility to simulate all network elements, variables and conditions (Figure 7).…”
