基于DSP技术的新型微机线路保护装置

Line protection based on DSP

介绍了一种基于数字信号处理器(DSP)芯片的新型微机线路保护装置。该装置采用数字保护、测控一体化设计,可同时实现输电线路的保护、测控、操作等功能。硬件方面采用32位定点DSP芯片TMS320F2812为核心部件,系统由CPU模块、模拟量采集模块、开关量输入/输出模块、液晶显示模块、电源模块和通信接口等模块统一组成。软件方面采用DSP芯片的集成开发环境CCS开发。

A line protection based on DSP（Digital Signal Processer） is introduced, which adopts integrative design of digital protection,measuring and control to realize the functions of transmission line protection,measuring,control and operation. With the 32- bit fix- point DSP as its core,the system hardware is composed of CPU module,analog sampling module,binary input/output module,LCD （Liquid Crystal Display） module,power supply module and communication module. The system software is developed in integrated development environment CCS（Code Composer Studio）.
