摘要
随着微电子技术、计算机技术和通信技术的发展,变电站自动化技术正以飞快的速度向前发展。基于嵌入式以太网的变电站综合自动化技术正在成为当前研究的热点。简要叙述了常规变电站及其微机保护的发展及其特点,对嵌入式以太网运用于变电站微机保护系统以及目前流行的处理器进行了探讨和阐述,介绍了基于ARM+DSP双CPU的微机保护硬件方案和软件整体方案。
With the development of micro-electronics technology,computer and communication technology,me substation automatization technology also develop quickly.The technology which based on embedded Ethernet is the research hotspot at present,The development and Characteristic of the general substation automatization and its microprocessor-based protection are briefly described, the embedded Ethernet which is applied in the substation microprocessor-based protection system and the popular microprocessor at present are discussed and exporuded,the hardware and software scheme based on ARM＋DSP double CPU microprocessor-based protection are pointed out.
