“十二五”期间海南电网将建设一体化电网运行智能系统，该系统的业务特点对调度数据网络提出了新的要求。介绍了一体化电网运行智能系统的业务需求和现有调度数据网的建设模式，以海南电力调度数据网建设为研究对象，从网络延伸、业务支撑、三层网络功能、带宽利用率等多个方面探讨网络拓扑及路由策略设计，提出一种兼顾多种业务数据流的海南电力调度数据网设计方案，对构建新业务条件下的电力数据网有一定借鉴作用。

Integrated grid operation smart system will be built in Hainan grid during the “12th five-year” plan period, in which new demands for dispatching data network have been put forward with the business characteristics. The business needs of intelligent system of integration grid operation and the building features of dispatching data network are analyzed in this paper. Then, the network topology and routing strategy design are discussed from some aspects: network extension, business support, three-layer network function, bandwidth utilization and so on, taking the construction of power dispatching data network in Hainan as an example. Finally, a preliminary construction scheme of Hainan power dispatching data network is proposed, which could take account of various business transmission flow and have a certain reference to the power data network under new business conditions.
