配电终端NAT方式接入调度数据网

Feeder Terminal Unit Access to Power Dispatching Data Network in NAT Mode

配电网作为输配电系统的最后一个环节,其实现自动化的程度与供用电的质量和可靠性密切相关。配电自动化是智能电网的重要基础之一。配电终端可通过接入音频电缆、载波通信、光纤等多种方式接入调度自动化主站系统。随着电力调度数据的建设与使用,基于电力调度数据网的网络方式最经济、可靠。介绍了通过公、私网IP地址转换接入电力调度数据网的方法,从而解决了IP地址池空间不足的问题。

Power distribution network is the last link of the transmission and distribution system,whose automation level is closely related with the quality and reliability of power supply. Distribution automation is one important basis of smart grid. Power distribution terminal can be connected to scheduling automation master station system via various modes,such as audio cable,carrier communication,optical fiber and so on. With the construction and application of electric power dispatching data,the network mode based on power dispatching data network is the most economical and reliable. This paper introduces dispatching data network access methods through public and private network IP address translation,thus solving the shortage problem of IP address pool space.
