基于中间数据库的PSS/E与BPA数据转换的研究

Study on PSS/E and BPA Data Transform Based on Intermediate Database

针对现有电力系统仿真软件PSS/E与BPA间存在的数据异构,不利于软件间数据共享和对比分析计算的问题,分析了基于中间数据库的异构数据源的转换方法,给出模式转换和数据转换实现过程;根据此方法将潮流数据和动态数据从源数据库中读出,通过PowerWorld中间数据库写入目的数据库,完成PSS/E与BPA异构数据的转换。以标准IEEE9节点系统为例进行数据转换和仿真对比分析,仿真结果显示PSS/E和BPA的潮流计算和暂态稳定性计算结果基本相同,证明数据转换是正确的。可见,基于该方法实现PSS/E与BPA的数据转换是可行的。

Aiming at data isomerism between power system simulation software PSS/E and BPA which is to the disadvantage of data sharing and comparison analysis and calculation, this paper analyzes transform method for isomerism data source based on intermediate databasc and provides realization process of mode transform and data transform. According to this method, it reads out trend data and dynamic data from the source database and writes in the objective database through Pow- erWorld intermediate database. Hereto, it finishes isomerism data transform of PSS/E and BPA. Taking IEEE 9-node sys- tem as an example, it introduces data transform and analysis on simulation and comparison. The simulation result shows that results of PSS/E and BPA load folw calculation and transient stability calculation ane basically the same. Meanwhile, the simulation result proves this method for data transform is correct. Therefore, the way of PSS/E and BPA data transform based on this mcthod is feasible.
