实时数据库是电网调度自动化系统的核心组成部分,目前的实时数据库主要在一个系统的局域范围内提供实时数据服务,无法支持多个系统间广域范围的实时数据存储和共享.文中分析了现有电网调度自动化系统实时数据库的系统架构,在此基础上提出了适用于广域环境的电网调度分布式实时数据库系统体系架构,讨论了该架构下实时数据的存储、定位、冗余、同步、安全等关键技术,并展望了其应用前景.%The real-time database (RTDB) is one of the core components of the power dispatching automation system. The current RTDB mainly renders real-time data service to a local-area system, while unable to support real-time data storage and sharing among wide-area systems. An analysis is made of the current architecture of RTDB systems, based on which an architecture of a wide-area distributed RTDB system for power dispatching automation systems is presented. The key technologies of the architecture such as storage, location, redundancy, synchronization, security, etc are discussed and the prospects for future applications are given.
