Abstract
In order to reduce the transient fault diagnosis error,expand the diagnosis range and improve the diagnosis accuracy,a power system transient fault event diagnosis method based on knowledge base and rule base is proposed.The niche genetic al-gorithm is used to reduce the power system transient fault event decision table graph,obtain the transient fault event fault rule set,and establish the transient fault event knowledge base according to the rule set.The weight coefficient of the target transi-ent fault event is determined through the evidence fusion theory.Combined with the correlation degree,the grey similarity be-tween the target case and the case in the knowledge base is obtained,and the matching results between the two cases are ob-tained to complete the transient fault event diagnosis.Experiments show that this method can accurately diagnose transient fault events.When the resolution coefficient ranges from 0.4 to 1.0,the root mean square error is 0.The accuracy of transient fault event diagnosis is still high when the proportion of information loss is different.关键词
