摘要
介绍了ARM内核嵌入式微控制器的性能特点,并针对电力系统继电保护的功能要求,提出了以ARM微控制器为核心,辅以复杂可编程逻辑器件(CPLD)的嵌入式综合数字继电器的设计思路及实现方案。通过对CPLD进行不同编程,该设计还可用于众多其他智能电器应用领域。最后,通过EMC试验及性能测试,给出这种应用的可行性结论。
The characteristics of embedded microcontroller with ARM core were introduced. Aiming at the functional requirements of relay protection in power system, a way to design and realize the embedded integrated digital relay was presented, in which an ARM microcontroller working with CPLD together was used as the kernel part of system. By programming differently in CPLD, the design can be also used in many other application fields of intelligent electrical apparatus. A conclusion about the feasibility of the research was given through carrying out some experiments of electromagnetic compatibility technique （EMC） and performance tests.
