摘　　要：在现代电力系统中,继电保护装置是保证电力系统安全运行和监控电能质量的重要工具。传统微机继电保护装置,存在计算速度较低和保护原理不够完善等问题。介绍了一种基于TMS320F2808+N78E366A双核继电保护装置,设计了装置的各个硬件模块,比较了全波傅氏算法和差分全波傅氏算法的滤波性能,并通过仿真计算对上述两种算法性能进行验证,选定系统的算法及采样点数,最后给出了系统主要的软件流程图。该装置运算速度快、可靠、便于维护、抗干扰能力强、体积小,并且根据用户的需要可方便地配置各种不同类型的测控保护。In the modern power system, relay protection device is an important tool to ensure the safe operation of the power system and monitor the quality of electricity. Traditional microcomputer relay protection device has a low computing speed, and its protection principle is also imperfect. A device of relay protection based on dual cores TMS320F2808 ＋ N78E366A is developed, the hardware of each module part is designed. The filtering performance of the full wave Fourier algorithm is compared with the differential full wave Fourier algorithm. Then the performance of the above two algorithms is verified through simulation, meanwhile the system algorithm and the samp selected. Finally, the main program diagrams of system software have also been given. The device is fast lng points are reliable, easy to maintain, strong anti-interference, cute size, and can been easily configured into various types protection and control according to users＇ needs.
