New technology applied to a restoration of electrical power substation

This paper presents a new approach based on a connection of two techniques applied in artificial intelligence to solve problems of restoration of electrical power substations. The techniques are: the four-valued annotated paraconsistent logic - 4vAPL and the case-based reasoning - CBR. This linking process happens in the manipulation of the functions of belief, disbelief, expertise and temporality of the 4vAPL for the recovery of cases to determine process diagnostics of a CBR. The 4vAPL is the support applied to the problems that present inconsistent, partial, undefined information. The domain of CBR is applied in the restoration of an electrical power substation. Thus, it approaches the system under study to real situations.
