چکیده

The paper is devoted to fault diagnosis problems using fuzzy decision making. We investigate dynamic diagnostic systems which can be represented by symptom-fault rule bases. The main question to be answered is what faults produce observable symptoms in the first moments of their appearance. To solve this task we propose to use a set of agents for making fuzzy hypothesis about symptoms and to solve inverse fuzzy relations.

Application of Multi-Agent Technology to Fault Diagnosis of Power Distribution Systems

When a fault occurs in a power system, the protective relays detect the fault and trip appropriate circuit breakers, which isolate the affected equipment from the rest of the power system. Fault diagnosis of power systems is the process of identifying faulty components and/or sections by analysing observable symptoms (telemetry messages). As the domain itself is characterised by dynamic situati...

Cooperative Multi-Agent Diagnosis Substation Faults Based on Artificial Immune Theory

Based on Multi-Agent (MA) technology and Artificial Immune (AI) theory, a novel substation fault diagnosis approach is proposed in the paper. The method firstly considers substation fault diagnosis a global complicated problem in uncertainty environment, and decomposes it into several relatively-simple local sub-problems based on ontology concept. Then diagnosis agent is respectively designed f...
