摘要
结合大型变压器微机保护的开发实践,对保护系统的硬件设计、不同保护原理的综合应用以及保护软件的编程实现方法等方面进行了研究和探讨。所开发的保护装置集主、后备保护于一体,通过采用高性能的TMS320C6713DSP作为保护CPU和配备带有嵌入式Linux操作系统的ARM处理器作为管理机,满足了复杂保护的应用要求。主保护通过综合采用多种保护原理,充分发挥不同保护原理的优势,进一步提高保护的综合性能。同时,借助功能强大的硬件平台,在软件设计中采用基于"继电器"功能模块的设计方法,实现了程序的模块化和透明化,提高了软件开发效率,且易于维护和扩展功能。目前,该装置已通过静模测试和动模实验。
During the development of microcomputer protection for large transformer,its hardware design,software programming and protection principle integration are researched. It combines the main protection and the backup protection together,takes TMS320C6713 DSP as its protection CPU and ARM processor with Linux operating system as supervisor to meet the requirements of complex protection. The integrated application of different protection principles enhances its comprehensive performance. Based on the powerful hardware platform,the modularized software design based on relay functions makes the programs transparent,which increases development efficiency and simplifies software maintenance and expansion. The developed protection has already passed static and dynamic tests.
