高速铁路供变电工程投资对比分析

随着对高速铁路认识的不断加深,作为高速铁路电气化工程重要组成部分的供变电工程技术也不断完善。从高速铁路供变电工程的内容、特点入手,结合实际工作中编制高速铁路供变电工程概预算的方法,分析高速铁路在速度目标值为250 km/h与300 km/h情况下影响供变电工程投资的主要因素及投资对比情况;从投资对比分析结果可知,影响高速铁路供变电工程投资的关键因素是牵引变压器容量及牵引变电2×27.5 kV配电装置类型。

A Comparative Analysis of Traction Power Supply Project Investment in High-speed Railway

Along with the deepening understanding of the high-speed railway, as important parts of electrification engineering projects in the high-speed railway, the engineering technology of the traction power supply project in the high-speed railway is being continuously perfected. In this paper, based on the contents and characteristics of traction power supply projects, combined with budget making methods in the traction power supply project in practice, the main investment influencing factors of traction power supply project and contrast results of the investment are analyzed under the respective conditions that the targeted speed value reaches 250 km/h and 300 km/h; from the comparison and analysis of investment, the capacity of traction transformer and the type of 2 × 27.5 kV distribution equipment are the key factors influencing invest- ment of traction power supply projects in high-speed railway.
