摘要
随着我国铁路建设的持续发展,对高速铁路与普速铁路同场并站区段(简称高普同场并站区段)牵引供电的可靠性及安全性要求日益提升,但因牵引供电方案受多因素影响,难以获得最佳方案。采用层次分析法对高普同场并站区段牵引供电方案进行比选,综合考虑建设投资、工程实施、路网规划、运营收益、供电可靠性、运营维护6个影响因素进行分析。结合典型工程案例,通过建模比较权重向量和特征值,实现全生命周期内对不同方案进行比选,以确定最佳供电方案。
With the continuous development of railway construction in China,the traction power supply in the sections with shared station and yard for high speed railway and conventional railway requires a higher level of reliability and safety,but it is difficult to obtain the best traction power supply scheme due to various factors.In this study,the traction power supply schemes for sections with shared station and yard for high speed railway and conventional railway are compared using the analytical hierarchy process(AHP),and six influencing factors are carefully considered,including construction investment,project implementation,railway network planning,operating income,power supply reliability,and operation and maintenance.The paper analyzes typical engineering cases and compares several power supply schemes over the course of the life cycle to identify the best one based on the modeling and comparison of weight vectors and characteristic values.
