Fault identification using multiple information sources in smart distribution grids

This paper outlines research and development work to use multiple information sources for improves the traditional outage management system. The architecture was designed considering a smart grid environment. The methodology presented allows the automatic solution of the fault identification and fault location problem in distribution systems using a methodology based on a fuzzy inference system. A pilot system using the proposed methodology has been implemented in an electrical utility in South of Brazil. To illustrate the paper are presented results and preliminary analysis from real situations based on historical data.
