提出了一种配电自动化终端接入电力调度数据专网的实现方案,该方案采用内部服务器端口地址映射技术引入私网来解决电力调度数据专网接入层的IP地址池过小问题。关键作法是通过1台路由器将配电现场通信子网接入电力调度数据专网并进行逻辑隔离,配电现场通信子网作为私网仅开放104远动规约服务端口,且不能主动向电力 This paper proposes a realization scheme that the distribution automation terminal accesses the power dispatching data private network. This solution uses the internal server port address mapping technology to introduce the private network to solve the problem of too small IP address pool in the power dispatching data private network access layer. The key approach is to connect the distribution subnet to the power dispatching data private network through a router and logically isolate it. The on-site communication subnet as the private network is only open to the remote protocol service port, and can not take the initiative to power
