基于DSP的微机保护综合实验装置设计

Design of integrative experimental device for microcomputer protection based on DSP

提出了一种基于32位高性能数字信号处理器(DSP)芯片TMS 320F 2812的多功能微机保护综合实验装置的设计方案。硬件方面在综合考虑各种实际微机保护装置硬件结构特点的基础上提出了一种通用型硬件平台的设计方案;软件方面采用代码在线更新和上电自举的设计方法实现对不同保护功能的软件配置。通过PC机远程下载不同的保护程序和相应的监控程序,装置可以实现包括各种电压等级的线路保护、母线保护、变压器保护等多种保护功能。实际运行和使用证明该装置具有较强的实用性。

A scheme of integrative experimental device for multi- function microcomputer protection based on 32-bit DSP（Digital Signal Processor） TMS320F2812 is designed. With the consideration of various microcomputer protection hardware structures,a general hardware platform is designed. Protective functions are software- configured by on- line refreshing and boot load. Different protection programs and corresponding monitoring and control programs are remotely downloaded with personal computer to carry out different protection functions including line protection,bus protection, transformer protection and so on for different voltage levels. Practices prove its good practicability.
