基于IEC61970的电力系统仿真数据库研究

随着电力系统的发展和软件工程技术的革命，电力系统仿真软件的更新和发展越来越快，这就对支撑仿真软件的仿真数据库提出了更高的要求。而现行开发的仿真数据库大多采用关系数据库系统，不能很好地满足面向对象编程的需要。该文利用ORACLE8i中先进的面向对象特性，提出了一种对象-关系型仿真数据库，能较好地满足面向对象编程的需要，具有良好的可扩充性和可维护性。同时，为了便于仿真软件之间或仿真软件与其它电力系统软件间的数据交换和共享，该文又利用了1EC61970标准中的电力系统资源公用信息模型(CIM)对电力系统器件进行建模，从而为仿真软件间的集成提供了平台。总之，该文提出了一种支持多种仿真软件集成的对象-关系型电力系统仿真数据库。

Research on Powersystem Simulation Database Based-on IEC-61970

With the development of powersystem and the revolution of software engineering technology, the development of powersystem simulation software becomes faster and faster. Most current simulation databases use relation database system for designing, and it does not meet the demand of object-oriented programming.This paper puts forwards an object-relation simulation database using the advanced object-oriented characteristic of ORACLE8i,which can meet the demand of object-oriented programming and has good expansibility , maintainability.At the same time, in order to facilitate the data exchange and share between simulation software and other software, the database system uses the powersystem resource's common information model(CIM) in IEC-61970 standard to model powersystem components. So it provides a platform for the integration of simalation software. In a word, this paper puts forwards an object-relation database system which supports the integration of simulation software.
