基于多目标智能加权灰靶理论的电力变压器状态维修决策

摘要

According to the grey uncertainty of electric power transformer status information,partial information is known,and partial information is unknown,a multi-attribute intelligent grey target condition-based maintenance decision model is proposed for electric power transformer in this paper.Based on the present maintenance situation of transformer,it is accurate to establish the gray vector of the transformer.And the maintenance decision can be effectively made,which combines with the calculation of the decision set.The multi-attribute intelligent grey target decision-making method is applied in electric power transformer,and the application results prove that the method is feasible.%针对电力变压器状态信息“部分已知,部分未知”的灰色不确定性,提出基于多目标智能加权灰靶理论的变压器状态维修决策模型.根据变压器目前的维修情况,确立灰局势向量,结合对策集的计算有效确定维修决策.实例分析结果表明该状态维修决策方法具有可行性.
