摘要本论文主要解决地铁轨道交通应急供电系统在正常供电或者辅助供电发生故障的情况下，利用应急电源进行紧急牵引，使地铁能够继续持续的运行到指定的安全的站点。基本原理是利用蓄电池存储的直流电和设计的逆变系统连接起来，把蓄电池应急电源中的直流电转换为列车可以正常使用的交流电供给列车作紧急牵引和列车上必要设备的正常供电。

主要的设计是蓄电池的选择和逆变系统的内部模块的设计，主要包括驱动电路，控制电路，滤波电路的设计。最后根据应急供电系统每个组成部分的特点和原理，把其各个部分组成一个完整的应急供电系统，并结合目前已经投入使用的系统来验证所设计的系统的合理性和创新性。整个应急供电系统能够确保列车在正常供电发生故障的情况下，使列车继续持续的运行，保证整个列车的行车安全，尽可能减少对出行旅客造成的影响。系统设计的主要难点在于逆变系统的各个模块的设计，尤其是滤波电路和驱动电路的设计，尽可能的减少系统存在的安全隐患，保证设计的完整性安全性。69192

Emergency Power Supply Scheme Metro Rail Transit Design

Abstract

This paper mainly solves Metro Rail Transit emergency power supply system in the normal power supply or the auxiliary power supply failure, the use of emergency power for emergency traction, so that Metro can continue to continue to run to the designated safe site. The basic principle is to use DC battery storage systems and design of the inverter connected to the emergency power supply battery current into alternating current supply train can train normally used for normal power supply emergency towing and train the necessary equipment.

The main design is the design of the internal battery module selection and inverter systems, including a driving circuit, a control circuit design, the filter circuit. Finally, according to the characteristics and principles of each component of the emergency power supply system, to form a complete emergency power supply system of its parts, and combined with the current system already in use to verify the reasonableness and innovative design of the system. Complete emergency power supply system to ensure the train in case of normal power supply failure, the train continues to continuous operation, ensure traffic safety throughout the train, to minimize the impact on passenger travel caused. The main difficulty lies in the design of the system design of each module inverter system, especially the design of the filter circuit and the drive circuit system as much as possible to reduce the presence of security risks, ensure the integrity of the security design.
