省级电力调度数据网带宽分析与容量规划研究

现有省级电力调度网络所有业务都在一张调度数据网中传输,网络的安全性和扩展性得不到保障,如何完善电力调度数据网第2平面结构,提高传送效率、保证通信能力成为突出问题。为此,根据省级电力公司调度数据网络现状和业务发展趋势,建立了"十二五"期间骨干数据网业务带宽测算模型。基于带宽预测结果,采用OPNET软件对甘肃电力调度数据网第2平面规划方案进行仿真建模,分析比较了不同阶段的网络结构对业务的适应性,综合考虑了链路带宽利用率、网络均衡度、网络重载链路比例等仿真指标,预测甘肃省电力调度数据网不同业务发展阶段的网络瓶颈,形成链路和网络升级策略,最终提出甘肃电力调度数据网第2平面容量规划建议方案。

Study on Bandwidth Analysis and Capacity Planning of Provincial Dispatching Digital Network

At present,all business of provincial power dispatching network was transmitted by the same network,so both security and scalability were failed to ensured and it made the perfection of the structure of the data access network,which was relatively independent of existing dispatching data special network,the improvement of transmission efficiency and the ensure of communication capability become major problems.For this reason,according to present situation and business development trend of provincial power dispatching data network,a bandwidth estimation model for the business of backbone data network during the 12th five-year plan was built.Based on results of bandwidth estimation,the modeling and simulation of the data access network for Gansu provincial power dispatching data network were performed by OPNET software,and the adaptability of network structure in different stages to business was analyzed and compared;comprehensively considering simulation indices such as link bandwidth utilization,network load balance factor,proportion of heavy-loaded link in the network and so on,the prediction of bottlenecks in Gansu provincial power dispatching data network in different development stages were performed,and then the upgrading strategy of links and network were formed.Finally,the suggestions on capacity planning scheme of the data access network for Gansu provincial power dispatching data network were put forward.
