摘　　要：针对目前继电保护消缺工作中主观性较强的问题,在传统工作的基础上引入了层次分析法,建立了基于层次分析法的消缺优化模型。该模型针对消缺工作的特点,以消缺最优化为目标,消缺中需要考虑的各因素为准则,待排查故障部位为方案,总结出了故障频度、运行环境、检测时间、影响范围等影响消缺排序的6大因素,将故障频度、检测时间直接根据实际数据运算,其他不易量化的因素则分为不同等级再转换为判断矩阵参与运算,最后得到了各可能发生故障部位的综合权重排序即为消缺排查的最优排序。研究结果表明,利用该优化结果进行排查可以避免继电保护消缺工作的主观片面性,提高消缺效率。Aiming at the problem of subjectivity in current eliminating defects work of relay protection system,the analytic hierarchy process（AHP）was introduced and a hierarchy optimization model was established.In view of the characteristics of eliminating defects,the model was established by setting the optimization of eliminating defects as the goal,impacting factors as the criteria and fault locations as the altematives,and six factors were summarized which could influence the order of eliminating defects,fault frequency,detecting time,affected area,etc..In the factors,the fault frequency and detecting time were calculated with real running data,otherwise the rest factors difficult to quantize were divided into different levels and then converted to judgment matrices.The order of the faulty positions sorted by their final weights was the optimal result.The results indicate that it could avoid the subjective one-sidedness and improve efficiency if staffs detect the positions of this optimized order.
