摘　　要：根据微机保护系统的发展趋势,提出了一种基于数字信号处理器(DSP)和高级RISC微处理器(ARM)双处理器结构的数字继电保护硬件平台的设计方案,介绍了数字式继电保护硬件平台的整体结构。该方案中保护CPU采用高性能32 bit浮点DSP芯片TMS320VC33,通过现场可编程门阵列(FPGA)进行输入/输出(I/O)扩展,配合16 bit并行模拟数字转换器,完成多通道高速率采样和保护计算的任务;控制中央处理器(CPU)采用具有ARM920T核的AT91RM9200芯片,完成人机接口和各种通信功能。经过试验,证实该装置可靠。According to the development trend of microcomputer protection system, a scheme of digital relay protection hardware platform based on DSP and ARM dual-CPU configuration is put forward, and the integral hardware structure of digital relay protection platform is introduced. The CPU for protection adopts 32 bit DSP TMS320VC33, which completes the tasks of multi-channel high-speed sampling and protection calculation through I/O expansion with FPGA （field programmable gate array） ,coordinated with 16 bit parallel A/D. The CPU for control adopts chip AT91RM9200 with the core of ARM920T ,which realizes man-machine interface and communication. The field trial operation proves its reliability.
