Simulation of Power Dispatching Data Network and the Influence of Routing Protocol Attacks

电力调度数据网的安全是智能电网安全运行的保障.通过仿真分析,可以评价电力调度数据网的安全性能,为部署安全措施和优化网络提供依据.本文在分析网络通信架构与业务特性的基础上,在OPNET仿真平台上对某省电力调度骨干网与变电站内部网络及承载业务进行了建模.模型中拓扑结构、设备链路、VPN(virtual private network)部署等网络配置均基于实际情况.在该模型上,对OSPF(open shortest path first)路由协议攻击进行仿真,研究路由协议攻击对省调中心与地调中心、变电站站控层之间通信时延、业务吞吐量、带宽利用率的变化,总结了不同场景下骨干网路由协议受到攻击后对电力调度数据网的业务传输的影响,揭示了电力调度数据网骨干网路由协议存在的脆弱性,所设计的仿真分析方法和仿真结果可为电力调度数据网运维部门改进网络安全性能参考.

The security of power dispatching data network is the important guarantee for the sate operation Grid. Through analysis and simulation, the safety performance of power dispatching data network can be evaluated to provide the basis for the deployment of security measures and optimization of network. Based on the analysis of a provincial power dispatching data network, the backbone, the internal network of the substation and the bearer services are modeled in this paper, whose topology, device link, VPN deployment, IP address planning and so on is close to the actual program. The scenarios that power dispatching data network under the routing protocol attack who based on OSPF is simulated for research the influence of the attack to throughput, link utilization and time delay from provincial dispatching center to municipal dispatching center and substation. At last, the influence of routing protocol attack to power dispatching data network in different scenarios is summarized. This paper reveals the vulnerability of routing protocol in the backbone network of power dispatching data network, the simulation analysis method and simulation results can be used to improve the network security performance of power dispatching data network to the operation and maintenance department.
