基于调度数据网的广域数据总线体系架构和关键技术

Architecture and Key Technologies of Wide-area Data Bus Based on Dispatching Data Network

总线作为调控系统的数据通信的基础,承担了系统内的数据交互工作。随着电网运行一体化特征日趋明显,当前总线难以满足跨越不同调度机构的调控系统间数据交互的需求。分析了智能电网调度控制系统总线的体系架构,针对调度数据网的特点,提出了适用于多级调度一体化协同运作的广域数据总线体系架构,并分析了电力调度域名管理、广域分布式代理、广域服务总线、广域消息总线等关键组成部分,实现了服务的广域共享和消息的高效传输。最后阐述了广域数据总线在电力系统中的应用前景。

As the basis of data communication for dispatching and control system, data bus assumes the work of the scheduling of data exchange. With more and more obvious integrated characteristics of power grid operation, the current bus is gradually difficult to meet the needs of data exchange between different dispatching agencies. The paper analyzes the architecture of the bus of smart grid dispatching and control system. According to the characteristics of the dispatching data network, a wide-area data bus architecture suitable for the integrated and collaborative operation of multi-level dispatching is proposed, and the power dispatching domain name management, distributed agencies, wide-area service bus, wide-area message bus key components of the wide area data bus are analyzed in order to achieve wide-area sharing of services an transmission of information. The application prospects of the wide area data bus in power grid are finally expounded
