Abstract

Power transmission networks play an important role in smart girds. Fast and accurate faulty-equipment identification is critical for fault diagnosisof powersystems;however, itisratherdifficult duetouncertain andincomplete fault alarm messages infault events. This paper proposes a new fault diagnosis method of transmission networks in the framework of membrane computing. WefirstproposeaclassofspikingneuralPsystemswithself-updatingrules(srSNPS)consideringbiologicalapoptosismechanism anditsself-updatingmatrixreasoningalgorithm.ThesrSNPS,forthefirsttime,effectivelyunitizestheattributereductionability of rough sets and the apoptosis mechanism of biological neurons in a P system, where the apoptosis algorithm for condition neurons is devised to delete redundant information in fault messages. This simplifies the complexity of the srSNPS model and allows us to deal with the uncertainty and incompleteness of fault information in an objective way without using historical statistics and expertise. Then, the srSNPS-basedfault diagnosismethod is proposed.
