Research On Database Technology In Substation Monitor System

Master Candidate:SUN DanSupervisor:Prof. Hu MinqiangThe database of Substation Automation System (SAS) is the base of data storage, analysis and information communion. The functional integrity and capability of database can influence the utility level of system directly. Reference to the practice of KT2000 Monitor System, the tendency to networking and open is discussed in this paper, and also the utility of database is researched and fulfilled. The main contents of this paper are as follows:1. Based on the design requirement, the software architecture and functional modules are segmented, the accomplishment of which is also described particularly.2. Web database and the Monitor System on the basis of web are analyzed. Also the Database Server and Web Server are accomplished, using the web database management system (Microsoft SQL Server 2000) and the dynamic web-page technology (ASP.NET).The information exchange and data communion can be more efficient and extensive.3. On the basis of the international standard of IEC 61850, which is being worked out, the specialities such as delaminating information, object-oriented data model, and Abstract Communication Service Interface are analyzed in detail. The design and method of implementing object-oriented real-time database which is conformed to IEC 61850 are proposed, and the database access interfaces also are illustrated. All these conduce to interoperability and expansibility in SAS.4. Describing the ideas for perfecting database system. The embedded real-time database system based on ARM can benefit networking in Monitor System.
