Application of one-dimensional methods for optimization for detecting the fault location in power distribution grids

Abstract

In modern power grids, one of the main issues in their operation is related to their reliability and provision of quality power supply to consumers. The requirements for the security, the operating regimes of the power distribution grids, the quality of electricity and the quality of the entire service of power supply are regulated by law. Regardless of the preventive measures, faults and accidents occur during the period of operation of the power distribution grids. For the purpose of analysis and control, the causes for accidents and the single outage duration and average durations of power outages are taken into account. The main factors determining the duration of the power outages are the type of fault, the facility type and the time for detecting the fault location. This publication focuses on some factors determining the detection time of the fault location on overhead power lines using optimization one-dimensional methods.
