摘　　要：为解决电网调控系统实时数据库面临的扩展能力差、处理性能不足、灵活性差等问题,提出一种基于NoSQL技术的分片集群实时数据库总体架构,并对该架构下的数据模型设计、数据分片策略、统一访问接口和动态扩容等关键技术进行研究分析。实测表明,基于该架构实现的分片集群实时数据库系统在实时性、吞吐量、扩展性和稳定性方面均有较大提升,能够有效支撑电网调控系统基础SCADA应用和各类高级应用功能。This paper proposes a general architecture of real-time database for power dispatching and control system based on NoSQL technology,which solves the problems of poor scalability,insufficient processing performance and poor flexibility faced by current real-time databases.The key technologies such as data model design,data sharding policy,unified API interface,and dynamic capacity expansion under this architecture are studied and analyzed.The measured results show that the real-time database of this architecture has been greatly improved in terms of real-time,throughput,scalability and stability,which can effectively support the basic SCADA application and various advanced applications of power dispatching and control system.
