基于SOA的海量准实时数据服务平台接入/访问研究

The research on mass real-time data service platform access/requirement based on SOA

摘要:

电网数据已成为电力企业发展的重要资产,但缺乏有效的技术手段对准实时数据进行高效的接入/访问。从松耦合、可重复性、标准化等架构设计原则考虑,通过数据接入方案和数据访问方案设计并实现了基于SOA技术的海量准实时数据服务平台。平台通过设计的数据接入/访问工具将不同业务系统的准实时数据统一接入,以测点形式有序集成,并统一对外提供订阅、查询和获取所需数据访问服务来支撑业务应用。同时通过平台电网模型同步与模型树建立和高级应用支撑的关键技术,建立主网模型,并借助变电站设备模型挂接完成主网与配网模型拼接,形成电网标准的模型树,实现电网准实时数据的高效集成和访问,更好的满足电力企业准实时数据纵向贯通和横向交互的需求。

Abstract:

Grid data has become an important asset of electric power enterprises, but the lack of effective technical means effectively real-time data access/requirement. Considering loose coupling, repeatability and standardized architectural design principles, the data access scheme and data access scheme are designed and implemented to realize real-time data service platform based on SOA technology. The platform USES data access/access tools designed to unify the real-time data of different business systems, orderly integration in the form of measurement points, and unified the provision of subscriptions, querying and obtaining the required data access services to support business applications .Meantime, the main network model is established through the platform grid model synchronization with model tree and advanced application support, Using the equipment model, finishing the main network and the distribution network model joining together,making the standard model tree of the grid,Realize the efficient integration and access of real-time data of grid,Satisfy the electric power enterprise real-time data interaction of horizontal and vertical penetration requirements efficiently.
