电力通信网络及其接入技术

Electric-communication Network and Its Access Technology

某电力系统通信自动化建设中的网络构成及其接入技术.系统由电话系统、计算机网络系统和宽带接入系统三部分组成,其网络接入采用了宽窄带一体化综合技术,骨干网采用SDH环网、末端采用星形网络,实现了系统内话音、远动、SCADA实时数据通信、图像监控信号传输等功能.系统的实际运行表明,该网络能够满足电力系统通信自动化的要求.

This paper has introduced the network structure and access technology of some one electric--communication in its automatication process. The system is made up of telephone system, computer network system and wideband access system. The access is by the integration of wide and narrow band, the backbone network by SDH ring network, the terminal by star network, which has realized the functions of speech, telecontrol, SCADA real-time data communication, picture control, and information transmission. The actual operation has showed that the network can meet the requirements of electric-communication automatication.
