摘要
Abstract
In the process of dynamic linkage of typical scenes of intelligent substation,the details of operation situation are single and redundant.In order to find the abnormal operation situation in time,a real-time online alarm method for ab-normal operation situation of intelligent substation under fuzzy evidential reasoning is proposed.Fuzzy evidence is used to in-fer the membership value under each feature vector,normalize it,and obtain all the membership values.According to the judgment criteria,the alarm samples are processed in time to narrow the alarm range,mine the abnormal operation situa-tion,predict the abnormal operation situation and faults that may occur in the intelligent substation,and automatically send an alarm by virtue of the Tdengine power operation and maintenance platform.The experimental results show that the pro-posed method has high recognition rate of abnormal situation,short time-consuming situation analysis,and short warning delay after adding noise.Clarify the relevance between various equipment.When one of the links has problems,send out a-larm information in time to avoid interlocking problems.关键词
