介绍一种面向能量管理系统(EMS)的高性能实时数据库设计方案。该方案以关系模型为基础进行内存库组织上的设计改进,从而支持电力模型的物理包容关系,支持符合IEC61970标准的物理模型、对象模型,支持EMS所特有的多研究态、多计算模式需求,达到了单表查询200万次/s、面向对象查询20万次/s的访问实时性,以及地级电网250个连接母线规模下网络分析计算时间小于400ms的实用化应用能力。 This paper introduces a high-performance real-time database design scheme oriented to energy management system (EMS). Based on the relational model, this scheme improves the design of memory bank organization, supports the physical inclusion of power model, supports the physical model and object model conforming to IEC61970 standard, supports multiple research states and multi-computing mode requirements unique to EMS, Achieved a single table query 2000000 / s, object-oriented query 200000 times / s access to real-time, and the level of power grid connection scale 250 bus network analysis and calculation time is less than 400ms practical application ability.
