Fault Location in Power Distribution Systems using ANFIS Nets and Current Patterns

The electric power markets have imposed new power service quality that make fault location in power distribution systems a mandatory issue. In this paper, a fault location approach based on the current waveforms measured at the power substation, the knowledge of protective device settings and ANFIS nets is presented. As a result, the approach may locate the faulted zone by using current descriptors. As a result, the ANFIS nets have proved the capability to locate the fault in a specific zone of the power distribution system. Result shows validation errors lower than 1% to locate faulted zones
