基于DSP的新型微机线路保护装置的研究

介绍了一种基于DSP芯片的新型微机线路保护装置的研究与开发，分别从硬件和软件两个方面阐述了其构成原理和设计方案。在硬件方面，本装置采用TI公司的32位浮点DSP芯片TMS320VC33作为数字核心部件，系统由管理庥护／测量CPU模板、信号输入／输出模板、键盘显示模板、电源模块等各模块统一组成：在软件方面，选用TI推出的用于开发其DSP芯片的集成开发环境CCS（Code Composer Studio），以C语言编程实现各功能。在DSP技术迅猛发展的背景下，DSP以其强大的运算处理能力、卓越的性能、低廉的价格，预示着这种设计方案具有巨大的潜力。代表着今后微机继电保护的发展方向。

The Research of a New Microcomputer Line Relay Protection Equipment Based on DSP

The paper introduces the research and development of a new microcomputer line relay protection equipment base on DSP. The principle of compositionality and the design proposal of both the hardware and software are expanded afterward. On the hardware, the equipment adopts the 32 bit floating DSP TMS320VC33 produced by TI as the digital central processing unit. The system is consisted of the management/protection/measurement CPU unit, signal input/output unit, keyboard display unit and power source unit. On the software, we choose the integrated development circumstance CCS (Code Composer Studio) that is developed by TI to assist its DSP development and applications. All the functions are implemented by C programs. The DSP solutions have indicated the great potential of this design because of its strong mathematical processing ability, prominent performance and low cost. This represents the development direction of microcomputer relay protection in the future.
