摘　　要：本文提出了基于OMAP-L137的铁路配电所馈线保护装置的设计方案。该方案采用了TI公司推出的双核数字信号处理器OMAP—L137芯片为核心，在设计中利用了双核处理器的DSP核进行运算以及ARM核进行接口控制，双核芯片的各自优势得到了充分的发挥，保护装置的处理速度和运算精度很大程度上得到了提高。在此基础上介绍了本保护装置的软、硬件结构，保护配置原理及判据。A design scheme about relay protection device for feed line of railway distribution substation based on OMAP-L137 was proposed .The core of this scheme is a dual-core digital signal processor of TI, calculating by its DSP core and interface control by its ARM core in .It makes full use of the dual-core and greatly improves the processing speed and calculating accuracy of the relay protection device. According to this ,the framework, principle and criterion of protective configuration of the device were introduced.
