摘要
基于IEC60870-5-104规约,利用嵌入式ARM(Advanced RISC Machines)处理器强大的以太网通信功能和数字信号处理器DSP(Digital Signal Processor)实现微机距离保护功能。分析了ARM和DSP结构及双口RAM用于双处理器间的高速数据交换的特点。构造了距离保护的判据和算法。保护算法在Matlab仿真和试验中都验证了保护装置的可靠性、速动性、选择性、灵敏性。
A microcomputer-distance protection device based on IEC60870-5-104 system is developed which makes use of the strong Ethernet communication capacity of embedded Advanced RISC Machines （ARM） processor and fast digital signal processor （DSP） to realize microcomputer protection. The characteristics of ARM structure , DSP structure and dual port random access memory which is used to realize reliable and quick data transmission between two processors are analyzed. The criterion and the arithmetic of microcomputer protection are given .In the course of MATLAB simulation and experiments, the device is proved to be of security, quickness, selectivity, and delicacy.
