摘要
针对当前架空输电线路环境复杂、运行与维护效率低等问题,考虑在线监测和巡检数据对输电线路状态评估的差异性和互补性,提出计及数据时效性的输电线路状态综合评估方法。首先,构建基于在线监测数据的架空输电线路状态评价指标体系;然后,兼顾指标的主观和客观权重,提出基于层次分析法和反熵权法的输电线路状态动态评估方法;接着,计及不同数据的时效性特征,提出融合巡检数据和在线监测数据的输电线路状态综合评估方法;最后通过具体算例,验证了所提架空输电线路状态评价指标体系及综合评估方法的有效性和可行性。
Aiming at the problems of complicated current environment of overhead transmission lines and low efficiency of operation and maintenance,and considering differences and complementarity of online monitoring and inspection data for evaluation of transmission line status,this paper proposes a comprehensive evaluation method of transmission line status taking into account the timeliness of data.Firstly,it constructs an online transmission data evaluation index system for overhead transmission line status,and then considering the subjective and objective weights of indexes,it proposes a dynamic evaluation method of transmission line status based on analytic hierarchy process(AHP)and anti-entropy method.Based on timeliness characteristics,it proposes a comprehensive evaluation method of transmission line status combining inspection data and online monitoring data.Finally,it verifies the effectiveness and feasibility of the proposed overhead transmission line index system and the comprehensive evaluation method through specific examples.
