基于通用服务协议的广域数据透明访问框架及关键技术

Framework and Key Technologies of Wide-area Data Transparent Access Based on General Service Protocol

为了突破现有电网数据使用瓶颈,适应未来"物理分布,逻辑统一"的体系架构,支撑跨广域业务数据的访问需求,从数据访问透明性和服务位置透明性着手,基于现有电力系统通用服务协议,构建了广域数据透明访问的服务框架,形成了透明访问框架的部署方案。同时针对构建透明访问框架中所遇到的问题进行了分析,并通过基于全局索引的分布式数据流处理技术、跨区域的服务发现与管控技术,以及广域数据传输技术等关键技术的研究和使用,为构建广域数据的透明访问框架提供了技术支撑和实施保障。

In order to break through the bottleneck of current power grid data usage,adapt to the future"physical distribution,logical unification"architecture,and support the access requirements of cross wide-area business data,this paper starts with the transparency of data access and service location,constructs a transparent access framework of wide-area data and forms the deployment solution based on the existing general service protocol for electric power system.Meanwhile,the problems encountered in the construction of transparent access framework are analyzed.Through the research and application of key technologies such as distributed data stream processing technology based on global index,cross-region service discovery and control technology and wide-area data transmission technology,the technology is provided for the construction,technical support and implementation guarantee of transparent access framework of wide-area data.
