摘　　要：介绍了一种基于数字处理器DSP(Digital Signal Processor)的新型高压线路保护装置,该装置以DSP芯片TMS320VC33为核心构成。介绍了方向纵联保护、距离保护等一些新的保护功能配置及原理。保护软件以基于继电器功能模块的设计方法进行开发,包括主程序和定时中断程序两部分。简述了定时中断程序各模块的主要功能。该保护装置已通过全面的实验测试,具有工程实用价值。With DSP TMS320VC33 as its core,a protective device for high-voltage transmission line is developed. The configuration and principle of protective functions,such as directional pilot protection and distance protection,are introduced. The protection software is developed based on relay functional modules and consists of main program and timing interruption program. Module functions of the timing interruption program are described. The device has been fully tested and can be applied in practice.
