摘要
简要介绍了建立电网调度自动化运动数据传输双通道系统的意义及其在湖南电网的实现。该系统利用话音数据同传技术在国产电力载波通道上实现１路话音与１路１２００Ｂｄ运动数据信号（ＦＳＫ）同时传输。依据数据信号传输质量，该系统对运动数据传输双通道实现自动切换。系统主站端具有微机网络管理功能。
The paper describes the significance of establishing the double channels system fortelecontrol data transmission in power pool dispatch automation system and it realization inHunan electric power system. By using the technology of speech and data simultaneoustransmission, speech and 1 200 Bd data (FSK) signals can be transmitted simultaneously in thehomemade PLC. According to the data signals transmission quality, the two telecontrol datatransmission channels can be switched automatically each other. Network management isprovided for in the master station by using a microcomputer.
