基于电力调度数据网的广域消息总线设计与实现

摘要

The demand for real-time data communication between multiple grid dispatching systems for notification,alarm and operation information in the interconnected large power grid is getting increasingly strong.But the message transmission services provided by the message bus in the grid dispatching system are confined to the local area of single systems for lack of common and efficient technical means for wide-area real-time information exchange between multiple systems.The characteristics of the current message bus are analyzed.On this basis,the wide-area message bus is proposed for wide-area real-time data communication.The architecture of wide-area message bus based on electric power dispatching data network is studied.Key technologies in the architecture,such as subscription,synchronization,monitoring,pushing,tracking and reliable message transmission are described.Wide-area message bus has established a real-time message transmission mechanism penetrating through the multiple grid dispatching systems,which is able to effectively enhance versatility,reliability and high efficiency of message transmission between wide-area applications.%互联大电网中各电网调度系统间通知、告警、运行信息等实时数据通信需求日益强烈,而目前电网调度系统中的消息总线提供的消息传输服务局限在单一系统的局域范围内,缺少通用、高效的多系统间广域实时信息交互手段.分析了现有消息总线的特点,在此基础上提出了适用于广域范围实时数据通信的广域消息总线,研究了基于电力调度数据网的广域消息总线架构,介绍了该架构下广域消息的订阅、同步、监控、推送、跟踪、可靠传输等关键技术.广域消息总线建立了贯通各级电网调度系统的实时消息传输机制,能够有效提高广域范围各应用之间消息传输的通用性、可靠性和高效性.
