【摘要】：为提高输电线路的防雷性能,提出了基于改进层次分析法(IAHP)和模糊综合评估法(FECM)的500 kV输电线路防雷改造评估方案。根据"初选—优选—验证"的评估流程,对几种典型防雷改造措施进行经济技术性分析,验证其有效性并得到备选方案。根据目标与准则之间的关系,采用改进层次分析法计算各措施相对于目标的权重值。在此基础上,采用模糊综合评估法对各个方案进行评估计算,由评价因素矩阵得出相应隶属度,从而确定各防雷措施的评价等级。结果表明,采用改进层次分析法能够较为快速、准确地得到各防雷改造措施的评估权重值,进而利用模糊综合评估法划分其隶属等级,可直接查看防雷改造效果的优劣。对某500 kV输电线路进行了防雷改造效果评估,结果与实际统计数据基本相符。
[Abstract]:In order to improve the lightning performance of transmission lines, the analysis method based on the improved analytic hierarchy process (IAHP) and fuzzy comprehensive evaluation (FECM) lightning protection evaluation scheme of 500 kV transmission line. According to the primary - preferred - Verification evaluation process of analysis for economy and technology into several typical lightning protection measures, verify its effective and get the alternatives. According to the relationship between goals and standards, using the improved AHP method to calculate the measures relative to the target weight value. On this basis, using fuzzy comprehensive evaluation method to evaluate the calculation of each scheme, the corresponding membership derived from the evaluation factor matrix, so as to determine the evaluation level. The results show that the lightning protection measures and by using the improved AHP method can rapidly and accurately get the weight of each evaluation of lightning protection measures, and the classification of the grade of membership by the method of fuzzy comprehensive evaluation, can be straight The effect of lightning protection is examined and the effect of a 500 kV transmission line is evaluated. The results are basically consistent with the actual statistics.
