摘要
能量管理系统（ＥＭＳ）有状态估计、在线潮流计算等许多应用功能。应用面向对象的数据库设计思想，将ＥＭＳ的网络数据分成３类：原始数据、控制数据、被控数据。在所有应用功能中，原始数据是固定的，单独作为一个数据库；控制数据和被控数据是变化的，一起作为另一数据库。再应用数据库家族的概念，这种做法将能灵活处理应用功能间的协调配合，方便新增功能，减少程序代码的重复量，并可大量节约内存和磁盘空间的开销，用户比较各应用功能的结果也十分方便。
The data for energy management system (EMS) can be divided into three types by using the object-oriented idea. The first type is primary data that is kept constant in all analysis functions. The second and third types are control data and controlled data. The controlled data vary as the control data vary. The control data and the controlled data of these functions are most likely to be different from each other. The concept of family is used to distinguish different data sources from different application functions in EMS. With this approach. the GUI refreshing program for all the application functions of EMS is the same. the programming is improved and largely simplified as well as large memory and disk space are saved. EMS application functions are easy. This approach has been successfully implemented in a real-life EMS in China.
