电网调度自动化前置子系统实时数据库的设计与实现

前置通信子系统是电网调度自动化系统的基础.分析了调度自动化诸多应用系统的数据通信和数据处理流程特点后,采用统一建模语言(UML),提出适用的前置通信模型.利用商用数据库管理系统(如 Oracle)定义和保存前置通信数据模型;第4代前置子系统实时数据库是在共享内存构建按地址(指针)直接访问数据的实时数据缓冲区,可以满足调度自动化诸多应用系统实时性和可靠性的要求;前置应用数据模型包含厂站、设备、协议、量测、注册5个包,每个包又由若干个类组成.论述了实时数据通信模型、实时数据缓冲区等的设计和实现.

Design and implementation of front-end subsystem real-time database for power dispatch automation

Front-end communication subsystem is the basis of power dispatch automation system.The features of data communication and processing in various application systems of power dispatch automation are analyzed and a front-end data communication model based on UML(Unified Modeling Language) is put forward.It is defined and saved in the commercial database,such as Oracle.The real-time database of the fourth generation front-end subsystem is the real-time data buffer created in the shared memory,where data is dire...
