基于4G网络的配电自动化系统通信子系统
|
摘要
为了实现基于4G宽带技术的配电自动化系统DAS的通信服务子系统,采用4G LTE技术实现配电馈线终端FTU的网络接入.针对用户需求,在其与移动运营商之间物理专线的基础之上,利用运营商提供的集团客户VPDN业务,采用L2TP over IPSec技术实现了DAS与FTU之间的VPN网络通道,达到配电自动化信息安全传输的目的.基于所构建的通信网络,进行DAS通信服务器软件的设计,实现了DAS系统数据采集和输出控制的通信功能.实验结果表明,所构思实现的通信子系统达到了通信功能和网络安全的指标要求.
In order to conceive and design the communication service subsystem of a DAS based on 4 G broadband technology, the network access of FTU is realized by using the 4 G LTE technology. For users' needs, in order to achieve the purpose of information transmission in distribution automation system, the VPDN services are adopted which provided by operators to group customers, and L2 TP over IPSec technology is used to realize VPN network channel between DAS and FTU on the basis of the physical private line between the user and mobile operators. In the light of the constructed communication network, the DAS communication server software is designed, and the communicating function of data acquisition and output control is realized. The test results show that the requirements of communication function and network security have been realized at the communication subsystem.
