智能电网中智能配电数字终端的消息设计

摘要

Smart power grid is a system that can realize real-time monitoring to users and equipments. It uses a variety of informa-tion to improve reliability, economy and flexibility of the smart power grid, and provides a more complete and convenient network sta-tus display interface for the grid operation and management to help the original grid to realize the running of the new intelligent power grid.The smart power grid includes smart power generation, transmission, distribution and power-transformation.The software of the intelligent digital terminal described in this article is divided into application logic, business logic, message control, equipment management and fundamental construction according to its cohesiveness and commonality.It reduces the coupling between layers. Since there is a lot of data needed to be collected, this system adopts the event driven mechanism based on reactor mode, so as to en-sures the real-time performance of the system and improve the efficiency of the system.%智能电网是一个能够实现对用户和设备进行实时监视的完整体系,是利用各种信息提高电网的可靠性、经济性和灵活性,为电网运行和管理人员提供更完整、便捷的电网状态显示界面,帮助电网实现智能化运行的新型电网.智能电网包括智能发电、智能输电、智能配电和智能变电4个部分.在此,智能配电数字终端软件系统根据内聚性、通用性划分为应用逻辑、业务逻辑、消息控制、设备管理和基础构建5个层次,降低了层与层之间的耦合性.在智能配电网中智能配电数字终端需要采集的电力数据和数据来源很多,为了管理多个事件源和消息源,采用了基于反应器模式的事件驱动机制,保证了系统的实时性,提高了系统的工作效率.
