应用于电网调度自动化系统的实时数据库的设计与实现 DESIGN AND IMPLEMENT ABOUT REALTIME DATABASE APPLIED IN ELECTRIC POWER NETWORK DISPATCHING AUTOMATION SYSTEM ABSTRACT This paper introduces the development status quo of realtime database and the main content of realtime database included.Explain the shortage of some commercial realtime database applied in electric power network dispatching automation system. Analyze some shortage of the realtime database which used in some mainstream electric power network dispatching automation system.Through analyzing the shortage of these products and the concept of dispatching automation system supportting platform,design and implement a realtime database management system,which can apply in electric power network dispatching automation system. Through studing the data model of electric power network dispatching automation system,first implement six layers realtime database managerment mode.The six layers include database,tableblock,table,fieldgroup,field,subfield.This paper explain the detailed design and implement of this realtime database management system,and explain the share memery management and the distribution of the realtime data in share memery. The performance of realtime database will be influenced by searching record.Trough studing the data model and the data relationship of electric power network dispatching automation system,this realtime database system provide three kinds of ways to searching records.1.Searching records through hash table.2. 第2页共64页应用于电网调度自动化系统的实时数据库的设计与实现 DESIGNAND IMPLEMENT ABOUT REAI肛ME DA：I!ABASE APPLIED IN ELECTRIC POWER NETWORKDISI嗡TCHING AUTOM娜ON SYSTEM ABSTRACT This paper introduces the development status quo of realtime database and the main content of realtime database included．Explain the shortage of some commercial realtime database applied in electric power network dispatching automation system． Analyze some shortage of the realtime database which used in some mainstream electric power network dispatching automation system．Through analyzing the shortage of these products and the concept of dispatching automation system supportting platform，design and implement a realtime database management system，which can apply in electric power network dispatching automation system． Through studing the data model of electric power network dispatching automation system，f'nst implement six layers realtime database managerment mode．The six layers include database，tableblock，table，fieldgroup，field，subfield．This paper explain the detailed design and implement of this realtime database management system，and explain the share memery management and the distribution of the realtime data in share memery． The performance of realtime database will be influenced by searching record．Trough studing the data model and the data relationship of electric power network dispatching automation system，this realtime database system provide three kinds of ways tO searching records．1．Searching records through hash table．2． 第2页共“页
