An Improved Method of Faulted Section Identification Algorithm in Distribution Automation System

  • 발행 : 2007.04.01

초록

This paper proposes an improved fault indication algorithm in a distribution automation system. A conventional fault indication method, so called YES-NO algorithm, could generate wrong informations under certain conditions such as line to ground fault, large motor double circuit line. In order to prevent mal-operation of fault indicator, direction of fault current are used as well as magnitude. The feasibility of the proposed algorithm has been testified by computer simulation using Matlab power system toolbox.
