摘　　要：智能变电站二次系统的状态评价是智能变电站状态检修不可或缺的一部分。针对目前智能变电站二次系统运行状态评价方法不能准确评估运行状态,提出一种改进的模糊综合评判法用于智能变电站二次系统的运行状态评价。引入均衡函数对指标权重进行优化,引入加权平均法完成权重向量和模糊关系矩阵的模糊综合。试验结果表明,所提出的二次系统评价方法可以较为准确和高效地评价二次系统的运行状态,为系统维护提供更加科学的指导。The state evaluation of the secondary system of intelligent substation is an indispensable part of the state maintenance of intelligent substation.In view of the fact that the current operation state evaluation method of the secondary system of intelligent substation cannot accurately evaluate the operation state,an improved fuzzy comprehensive evaluation method is proposed for the operation state evaluation of the secondary system of intelligent substation.The equilibrium function is introduced to optimize the index weight,and the weighted average method is introduced to complete the fuzzy comprehensive of variable weight vector and fuzzy relation matrix.The experiment results show that the proposed secondary system evaluation method can evaluate the operation state of the secondary system more accurately and efficiently,and can provide more scientific guidance for system maintenance.
