高速铁路典型线路接触网动态性能分析

Analysis of OCS Dynamic Performance of Typical High Speed Railways

铁路运营管理单位采取精细化维修措施以提升接触网运营效率,但也消耗了大量人力物力财力。为了控制运营维护成本并改善运营维护状况,研究接触网动态性能的变化规律。选取6条开通时间久且在运行速度和接触网结构上具有代表性的线路,以高速综合检测列车的接触网检测数据为基础,采用统计分析、聚类分析、关联分析等大数据分析方法,对所选线路近10年的接触网动态性能评价指标(CDI)和维修数据进行研究。结果表明:不同结构接触网的动态性能之间存在显著的优劣性差异,且各年间接触网动态性能上存在的微小差异主要与部分接触网维修有关。

Railway operation and management departments have taken refined maintenance measures to improve operation efficiency of catenary,which at the same time consumes a lot of manpower,material and financial resources.In order to control the operation and maintenance cost and improve operation and maintenance level,the dynamic performance of OCS is studied.6 sophisticated lines which are typical in both operation speed and OCS structure have been selected and their OCS detection data have been acquired by the high-speed comprehensive inspection train.Based on these data,the paper studies the Catenary Dynamic Index(CDI)and maintenance data of the selected lines in recent 10 years by adopting big data analysis methods such as statistical analysis,cluster analysis and association analysis.The results show that OCS with different structures show significant differences in their performance,and the minor differences in dynamic performance of OCS from different years are mainly related to the maintenance.
