摘　　要：在电力调度数据网双平面建设过渡期某些复杂场景下,要求厂站远动机通过数据网双平面独立响应只有1个IP地址的主站前置机通信连接。远动机应用静态路由技术则只能选择双平面之一作为通信网络,当所选择的平面发生网络故障时,远动机与主站通信中断且无法切换到备用平面。为此提出在远动机通信中应用策略路由技术,通过分析策略路由技术的各种可用方法,根据远动机通信报文特点,选择源地址匹配方法来解决该问题。试验结果表明,策略路由技术能在任一平面网络故障时,自动从备用平面响应同一主站前置机的通信连接,保障了电力调度数据网通信网络冗余的安全性。During the transition period of power dispatching data network biplane construction in some complex scenarios,the substa-tion remote terminal unit(RTU)is required to independently respond to the communication connection of the master station computer with only one IP address through the data network biplane.The RTU application of static routing technology,only one of the biplane can be selected as the communication network.When a network fault occurs in the selected plane,the communication between RTU and the master station are interrupted and cannot be switched to the standby plane.Therefore,the application of policy routing tech-nology in RTU communication is proposed.Through analyzing the various available methods of policy routing technology,according to the characteristics of RTU communication messages,it selects the source address matching method to solve this problem.The experi-mental results show that when policy routing technology can occur the network fault in any plane,it automatically responds from the standby plane to the communication connection of the same master station computer.It ensures the redundancy security of the commu-nication network of the power dispatching data network.
