Analysis of AT Power Supply Network in AC Electrified Railway

摘要

摘要: 为深入了解交流电气化铁路AT(自耦变压器)供电网络,明确物理概念,利用基于两相对称分量变换的复合序网分析法,给出了牵引网、自耦变压器、牵引变压器、牵引负荷和电源等网络元件的序模型及AT 供电网络复合序网的建立方法;定义了供电能力及其利用率,通过比较2X27.5kV AT供电模式与55kV AT供电模式的特点和性能,说明了供电能力与负荷供电容量需求之间匹配的重要性.仿真结果表明,基于两相对称分量变换的AT网络复合序网分析方法具有简单可行、物理概念清晰等特点.

Abstract: The method of compound sequence analysis based on two-phase symmetrical components transform was used to further analyze AT (auto transformer) power supply network in AC electrified railway with clear concepts. Sequence models for AT power supply network components were described, such as traction power network, auto transformer, traction main transformer, traction load, power source, and so on. The way of building compound sequence network for AT power supply network was proposed. The definitions of power supply capacity and power supply capacity utilization ratio were determined, and the importance of matching between power supply capacity and load power demand was demonstrated by comparing 227.5 kV with 55 kV AT power supply modes. Simulation results show that the method of compound sequence network analysis based on two-phase symmetrical components transform is applicable in precision and clear in concept.
