Abstract
According to the huge size of distribution networks and the uncertainties and imperfections of the alarm information after fault, this paper proposes a fault diagnosis method of distribution networks by the regional parallel reasoning based on rough set and Petri nets. This method includes three steps. First, distribution network is divided into several independent areas, and then establish fault decision table for each area respectively. Second, a rough set is used to optimize and extract diagnosis rules. Finally, after constructing petri nets model, fault diagnosis is finished through parallel reasoning of Petri nets. Test proved that this method can diagnose the fault rapidly and accurately, and it has the batter fault tolerance and adaptability.关键词
