架空线路运行安全状况预警机制研究

Research on the early warning mechanism of operating safety of overhead line

架空输电线路的安全与否,在很大程度上影响电力系统是否能够安全运行,影响整个国民经济的稳健发展。为了科学评估架空线路运行的状况,提出基于梯形模糊数层次分析法赋权的架空线路运行安全状况预警模型,并应用于马鞍山市某110 k V架空线路运行安全状况的预警评价中,得到了架空线路运行安全状况预警等级为"蓝色"水平,属于较安全状态的结论。

The safety of the overhead transmission line has a great influence on whether the power system can run safely,and it will affect the stable development of the whole national economy. In order to evaluate the operation of the overhead line,the paper puts forward a fuzzy comprehensive evaluation method based on trapezoidal fuzzy number,and applies the model to the safety status of the 110 k V overhead line in Maanshan. The study concludes that the safety warning remains at relatively safe level with a ＂blue alert level＂.
