电气化铁路双边供电技术应用研究

Discussion on Application of Bilateral Power Supply Technology on Electrified Railway

电分相问题一直是制约电气化铁路发展的瓶颈,在复杂艰险山区、大坡道、重负荷铁路中,该问题更加突出。电气化铁路采用双边供电技术可以同时取消牵引变电所出口处和两牵引变电所间分区所的电分相。本文从系统方案、技术可行性、供电安全性等方面对双边供电技术的应用进行探讨,并根据实际线路应用情况,验证了树形变电所群双边供电方案的优势和应用效果。

The problem of electrical phase separation has always been the bottleneck restricting the development of electrified railway,especially in complex and dangerous mountainous areas,large ramps and heavy-haul railways.The electrified railway adopts the bilateral power supply technology,which is able to cancel the electrical phase separation at the exit of the traction substation and the section post between the two traction substations at the same time.The paper discusses the application of bilateral power supply technology from the aspects of system scheme,technical feasibility and power supply safety,and verifies the advantages and application effect of bilateral power supply scheme of tree type substation group according to the actual line application.
