架空线路运行状态评估中的混合型多属性决策 摘要 随着电网规模的逐渐扩大，电力网络及其线路的结构也越来越复杂，线路的安全、可靠运行对电力系统有着极其重要的意义。对于架空输电线路运行状态可靠性的安全评价工作重要性也逐渐被人们所认知。但实际中架空输电线路具有分布地域广、检测参数多、运行环境复杂等特点，直接导致数据繁杂。因此，需建立一套简捷有效的评估手段。 输电线路是电网运行中重要的组成部分，同时也是我国电能供应中重要的组成部分。经济和社会的快速发展是离不开电能的供应的，因此一定要保证输电线路的运行安全和稳定，对输电线路进行合理设计和优化。在输电线路运行的过程中是存在着很多问题的，对出现的问题进行分析可以找到更好的解决措施，同时对输电线路也能更好的进行设计和优化，确保输电线路的安全运行。 对架空线路运行状态的评估应从与其影响因子着手，通过对其影响因子的合理设计和改进，再采用合理的方法进行混合型多属性决策。通过对架空线路运行状态评估中的混合型多属性决策，可以帮助我们避免线路故障的发生，进一步提高架空输电线路的运行水平。 关键词：架空线路；运行；设计；优化；评估；决策 OVERHEAD LINE RUNNING CONDITION ASSESSMENT OF HYBRID MULTIPLE ATTREBUTE DECISION-MAKING Abstract With the widening of grid scale, the electric power network and its circuit structure is becoming more and more complex, the line of safe, reliable operation of power system has extremely important significance. For the reliability of overhead transmission line running state safety evaluation work importance also been realized by people. But in the actual overhead transmission line has a wide distribution area, testing parameters, operation environment more complicated characteristics, led directly to the data and complex. Therefore, it is necessary to establish a simple and effective evaluation method. Transmission lines is an important part in the operation of the power grid, is also the important part of power supply in our country. Rapid economic and social development is inseparable from the electricity supply, so be sure to guarantee the operation safety and stability of the transmission line, make reasonable design and optimization of transmission lines. In the process of transmission line operation is there are a lot of problems, analyze the problems can be found better solutions, at the same time also can better for transmission lines to carry on the design and optimization, to ensure safety operation of transmission lines. For overhead line, the assessment should be in the running state of and affecting factors on the impact f
