摘要
介绍了一种可在自动化系统中应用的嵌入式智能继电保护装置 ,对系统工作原理、硬件构成、信号采集、软件设计作了具体说明。由于采用了高速、高性能 16位MPU ,软件中可引入复杂的滤波和分析算法 ,且外围电路大为减少 ,因而具有检测精度高 ,动作速度快、体积小和成本低等特点。以此取代传统的继电保护装置 ,取得了较好的效果。
An embedded intelligent protection relay device which is applicable in automation systems is presented. The operational principle, hardware configuration, data dcquisition, and software design of the system are described concretely. Due to high speed and high performance 16-bit MPU is adopted in the system, it is possible to lead complicated filter and analysis algorithm into software and reduce peripheral circuits. The system features high detection accuracy, fast response speed, compact, and low cost. Thus it is better to replace conventional protection reply device.
