分散式微机线路保护监控装置的设计

Design of Distributed Computerized Line Protection and Monitoring Device

随着科学技术的发展,国内外已研制生产出专为发电厂、变电站及高压送电线路进行保护监控的成套微机产品。发电厂变电站设计调试运行的快速化简单化智能化和习惯性的问题,为电力系统实现综合自动化提供了必要的条件。从装置的组成、人机界面、I2C总线接口系统、脉冲信号测量电路、输入输出控制电路、通信接口、系统的抗干扰设计、系统软件配置等多方面进行了具体的阐述,最终实现了分散式微机线路保护监控装置的设计。

This paper introduces the composition of the device,interface design,I^2C bus interface,the pulse signal measurement circuit,input and output control circuit,communication interface,the design of anti-interference and system software etc.Finally it is realized the design of distributed computerized line protection and monitoring device.
