摘　　要：为了适应现代超高压电网稳定运行的要求，微机距离保护装置在硬件和软件上都提出了越来越高的要求。本文在总结了输电线路微机距离保护研究现状的基础上，分析了国内现有微机保护硬件的现状，对比了8位、16位单片机（SCM）以及32位DSP的保护方案，并总结了其优缺点，提出了一种基于ARM微处理器的保护方案。本文将实时操作系统μC／OS—II与模块化硬件设计相结合，共同构成一个可以重复利用的软硬件数字系统平台，除了可以最大限度地提高开发的效率、减少资源的浪费外，还可以通过长期对于该平台的研究，逐步优化平台软硬件资源，提高其性能，并满足日益复杂的应用需求。本文尝试了用任务方式实现保护的并行处理，大大提高软件的可读性和可靠性，也为将来任务扩展提供条件。For adapting to requirement for working stably in the modem extra-high-pressure power network, microprocessor-based distance relays are required higher and higher on not only hardware but software. On the base of generalizing the existing condition of microprocessor- based distance relays at the power transmission line, this subject analyzed the existing condition of the hardware of distance relays, compared 8- bit, 16-bit SCM and 32-bit DSP protection scheme, and generalized there merits and demerits, then gave a scheme of relays based on ARM processor. This subject unifies real-time operating system μC/OS-II and the modulation hardware design, and constitutes one software and hardware number system platform. Besides maximum limit enhanced the efficiency of development and reduced the waste of resource, it may also enhance its performance with regarding the platform and optimizing the platform software and hardware resources. And it also meets the complex application need day by day. This subject attempts to realize the protection parallel processing with the duty way, it will not only enhance software＇s readability and the reliability greatly, but also provide the condition of the duty expansion.
