摘　　要：DSP数字信号处理能力强、运算速度快、片内外设丰富,CPLD长于接口电路扩展、时序控制、地址译码,以太网通信技术已经成为微机保护通信的新标准。基于这些最新技术的发展,文中研制了一套针对于中低压线路的双CPU结构的微机线路保护装置。文中详细介绍了该套装置的各个硬件模块单元的功能特点、软件流程图以及所采用的将半波傅氏算法和Mann- Morrison算法相结合的快速算法。该套装置已投入实际运行,效果良好。The DSP chip has powerful digital signal processing ability, high operation speed and abundant peripheral equipments. The CPLD chip specializes in interface expanding, time sequence controlling and address coding, ethernet has become the new communication standard of microcomputer relay protection. Based on these new technologies, one set of microcomputer relay protection device aims at the medium and low voltage transmission line is designed. The functions of every hardware module, software flow chart and adopted fast algorithm which integrates the half-wave Fourier algorithm and Mann-Morrison algorithm are introduced. The device has been put into application and generated good effect.
