摘　　要：该数据库是以二维自由表为基本存放数据的形式,将电力系统的设备参数按设备类型存入表中,并在PDSB的基础上实现与SCADA数据交换的功能。开发了实时生成潮流文件的系统,该系统基于PDSB的数据,结合SCADA实时得到母线负荷、发电、实际运行的网络结构等数据,快速准确地生成某种格式的潮流文件,作为系统稳定分析的源文件。Power system calculation data hase （PDSB） is used in the off-line electric power calculation data base system. The data base system stores device parameters into 2D free tables in terms of device types, and realizes data exchange with SCADA based on PDSB. A real-time power flow files creating system is developed. With real-time data about bus loads, generators, current electric power network structure and so on got from SCADA, the PDSB data-hased system can create power flow files in some format quickly and exactly. The created files are used as source files to analyze the stahility of the electric power system.
