Rough Set Theory-based Priority Decisionmaking for Maintenance of Substation Automation Equipment
Maintenance priority decisionmaking is an important part of the early work of equipment maintenance.When applied to maintenance priority of automation equipment,currently prevailing decisionmaking methods fail to achieve ideal utility,with poor balance of maintenance tasks and long duration of substation power outage.Aiming at addressing the aforementioned deficiencies,this work made an attempt to establish a rough set theory-based priority decisionmaking method for maintenance of substation automation equipment.The method design entailed the simplification of priority de-cisionmaking attributes by using rough set,the establishment of a decisionmaking index set,the collection of index data,and the quantification of maintenance priority by using weighting method,thereby realizing priority decisionmaking of e-quipment maintenance.The designed method was indicated by experiments to achieve maintenance task balance higher than 50％and facilitate obvious reduction in outage duration.
