Distributed real-time database for dispatching automation system with micro-services

提出一种含微服务的调度自动化系统分布式实时数据库总体构架,解决了传统调度自动化系统中实时数据库数据处理慢、灵活性差和不易扩展等问题。根据实时数据库对数据时效性的要求,定义了遥测类、遥信类的简化数据模型,规避了复杂数据关系的搜索,并运用数据分片技术对数据进行有效划分。采用微服务架构模式,将数据读写过程虚拟化为细粒度的数据服务,以云计算技术为核心,实现对微服务、分布式技术的深度整合。利用该构架实现的分布式实时数据库管理系统已在某实际电网中得到应用。实际运行效果表明,该构架下的实时数据库具有实时性高、扩展性强、运行稳定可靠等优点,为坚强智能电网的建设和发展提供技术支撑。

This paper proposes a new Distributed Real-Time Database(RTDB)architecture for a dispatch automation system with micro-services,which solves the problems of slow data processing,poor flexibility and difficult expansion in the RTDB of the traditional dispatching automation system.According to the requirement of RTDB for data timeliness,the simplified data model of telemetering class and remote signal class is defined,which avoids the search of complex data relation.Meanwhile,the data fragmentation technology is used to divide the data effectively.Utilizing micro-services architecture pattern,the data read and write process is virtualized into fine-grained data services,and the core of cloud computing technology is used to realize the deep integration of micro service and distributed technology.On this basis,the distributed real-time database management system has been applied in an actual power grid.The actual operation results show that the RTDB under this method has the advantages of high real-time,strong scalability,stable and reliable operation,and provides technical support for the construction and development of strong smart grid.
