郑西客运专线四电系统集成的安全性分析

摘要

四电系统集成的安全性是实现高速铁路高效可靠运营的基础和保证。以郑西客运专线四电系统为例，建立系统评价指标体系，利用改进AHP确定各个评价指标的权重向量和隶属度矩阵，并结合综合安全水平模糊综合评价法对郑西客运专线四电系统集成进行定性描述以及定量分析，分析结果表明郑西客运专线四电系统集成的安全性水平较高。%The safety of the integration among the four electric/electronic systems is the basis and guarantee for achieving efficient and reliable operation of high-speed railway. This paper, taking the four electric/electronic systems of Zhengzhou-Xi’an passenger dedicated line as the example, established a set of system evaluation indicators. And then, the weight vector and membership degree matrix of each evaluating indicator were determined based on the method of improved analytic hierarchy process. Further on, in combination with the fuzzy comprehensive evaluation method, the safety level of the integration among the four electric/electronic systems of Zhengzhou-Xi’an passenger dedicated line was described qualitatively and analyzed quantitatively. The analysis result supports the conclusion that the integration among the four electric/electronic systems of Zhengzhou-Xi’an passenger dedicated line can be of higher safety level.
