DIgSILENT公司开发的PowerFactory软件在国内外电力系统分析中得到了日益广泛的应用。然而,PowerFactory软件缺乏国内实用的同步发电机控制系统(励磁、调速、电力系统稳定器)模型和参数库,限制了其研究结论准确度的提高。针对这一问题,基于 PSASP 实际工程数据,选取实用的同步发电机控制系统模型类型,在PowerFactory中进行了建模实现,并与PSASP软件进行了仿真对比验证。两区域四机系统中的仿真对比结果验证了所建模型的准确性,为获得更为准确的电力系统分析结果打下基础。

DIgSILENT PowerFactory software is increasingly widely used in power system analysis in China and abroad. However,it does not have measurement-based models and parameters of the synchronous generator control system,such as the excitation system,the speed governor system,and the power system stabilizer,which will restrict the improvement of analysis result accuracy.To solve this problem,based on the actual data in PSASP proj ects,the measurement-based models of synchronous generator control systems are selected and established in PowerFactory.Case studies are conducted in a two-area four-machine system.Comparison results between PowerFactory and PSASP have validated the accuracy of the models developed,laying a foundation for obtaining even more accurate results of power system analysis.
