玉溪市地质灾害频发,电网覆盖广泛,电网遭受地质灾害的灾变损失较大。结合地质灾害对电网的致灾特点以及灾变损失的影响因素,构建了电网遭受地质灾害脆弱性的评价指标体系,采用层次分析法和熵值法相结合的方法,对玉溪市各区、县电网遭受地质灾害的脆弱性进行了主客观综合评价,并运用聚类分析进行等级区划。结果表明,玉溪市55.5%区县电网脆弱性等级较高。
Yuxi City, frequent geological disasters, power grids covered a wide range of power grid disaster suffered heavy losses of geological disasters. According to the characteristics of disaster caused by geohazard to power grid and the influencing factors of catastrophic losses, this paper constructs an evaluation index system for the vulnerability of power grid to geological disasters. By using the combination of analytic hierarchy process and entropy method, Disaster vulnerability of the subjective and objective comprehensive evaluation, and the use of cluster analysis level division. The results show that 55.5% of the districts and counties in Yuxi have a higher vulnerability level.
