    摘要:

    输电线路的安全运行是保障电能稳定传输的重要基础，而输电线路的运行状态受气象因素影响较大。为评估输电线路系统面临的综合风险，提出计及气象因素的输电线路安全性评估模型。首先根据输电线路架构的特点构建了反映输电线路运行状态的评估指标体系，同时基于图论原理提出一种新的图模型赋权方法，以克服传统物元可拓模型赋权中存在的人为主观因素缺点；其次以物元可拓理论构造了输电线路的综合风险物元及安全性评级，建立计及气象因素的输电线路风险安全性评估及动态管理模型；最后以某地区为例研究其输电线路的运行风险情况，分析结果验证该输电线路安全性评估模型的科学性和实用性。

    Abstract:

    The safe operation of transmission lines is an important basis for ensuring stable transmission of electric energy, and the safety is greatly affected by meteorological factors. In order to evaluate and improve the risk early warning capability in the transmission system, this paper proposes a transmission line safety evaluation model that takes into account meteorological factors. Firstly, according to the characteristics of the transmission line architecture, an evaluation index system reflecting the operation status of the transmission line is constructed. At the same time, a new graph model weighting method is proposed based on the principle of graph theory to overcome the human subjectivity factor disadvantages in the weighting of the traditional matter?element extension model. Secondly, based on the matter?element extension theory, the comprehensive risk matter?element and safety rating of transmission lines are constructed, and the risk safety assessment and dynamic management model of transmission lines considering meteorological factors are established. Finally, taking a certain region as an example to study the operation risk of its transmission lines, the analysis results verify the scientificity and practicability of the transmission line safety assessment model.
