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。
This paper briefly introduces the significance of establishing a dual-channel system for automatic dispatching of sports data in power grid and its realization in Hunan Power Grid. The system uses voice data synchronization technology in the domestic power carrier channel to achieve a voice and a road 1200Bd motion data signal (FSK) simultaneous transmission. According to the quality of data signal transmission, the system automatically switches between two channels of motion data transmission. The system master station has a microcomputer network management capabilities.
