基于知识库的BPA二次开发

Secondary Development of BPA Programming Based on Knowledge Base

对于现代电力系统,采用N-2原则进行电力系统稳定分析的难度不断地在加大,采用人工方式进行预想事故预演,即费时费力又容易产生遗漏。研究N-2安全稳定计算分析软件与现有BPA软件无缝衔接,引入知识库系统,识别电网中最为严重的事故以及可能存在的薄弱环节。在保证了仿真覆盖范围的前提下,大大地减少了仿真案例的数目,缩减了系统的仿真时间,实现了对电网的快速仿真。

For modem power system, the difficulty of using N-2 principles to execute the power system simulation increases constantly. The conventional way to rehearse the contingency manually is laborious and prone to omissions. Therefore, a new method is developed to identify the severest faults and the weakness of the power system, which makes a smooth combination of the N-2 security and stability calculation software with the BPA software and brings in the knowledge base. For the same side of grids, the new method needs only a few cases to simulate, which shortens the total simulation time, and thus achieve a fast simulation of the power system.
