基于AVR单片机的电网参数监控系统

AVR-based Supervising System for Parameters of Electric Power Grid

介绍了一种基于AVR单片机的数据监控系统,用以监控电网电力各项参数。通过按键、液晶屏与串口的配合,实现了数据的人机对话,可以根据需要随时修改系统参数。监控系统充分利用了AVR的两个独立的串口,通过可靠的串口通信协议,同时实现了与电网电力装置和上位机终端的数据交换。该监控系统已被成功应用于UPFC实验装置,完全满足系统要求。

A data supervising system based on AVR single chip computer is presented. The system is used to monitor various parameters of the electric power grid. The man machine interaction is realized by the combination of key button, LCD and serial port, thus the system parameters can be modified whenever it is necessary. Two of the independent serial ports of AVR have been fully used in the system ; through reliable serial communication protocol, data exchange with both electric equipment and the terminal of host computer can be implemented simultaneously. The system has been successfully operated in UPFC experimental equipment and met the requirement perfectly.
