摘要
地铁直流牵引系统馈线保护是直流系统的核心组件,是安全运营的前提保障。而随着微型计算机的发展,其在直流牵引系统方面的应用也越来越广泛。该论文阐述了基于ARM和DSP双CPU馈线保护装置的设计,对保护装置的硬件结构、软件设计方案进行了详细的分析。该装置模块化的设计方案,集测量、控制、保护、通讯于一体的功能,完全适用于综合自动化的管理。该装置已用于武汉三号线、四号线,成为全国首个全国产化线。随着全国直流牵引系统的发展,此装置有着更广泛的前景与经济效益。
The protection equipment is the core components for DC traction power supply system. As the development of microcomputer, it is widely used in DC traction power supply. This paper describes the DSP and ARM-based protection equipment for DC traction power supply system. It integrates measurement, control, protection and communication functions. This protection equipment has been used in Wuhan metro line-3.line-4. With the development of city metro, the protection equipment has broad prospect and great economic benefit.
