摘　　要：大型工业企业电网开展仿真建模时,根据描述电网结构的图形文件搭建仿真模型。针对这种情况,为提升仿真建模的效率,避免繁琐的手动建模过程,提出了一种电磁暂态仿真模型敏捷生成的新方法。首先,构建一种基于卷积神经网络(convolutional neural networks,CNN)的识别模型,用于识别图形文件中的电力元件;其次,基于矢量缓冲区提出一种判断电力元件连接关系的方法,用于识别元件之间的电气连接关系;最后,利用计算机程序生成相应的电磁暂态仿真数据文件。算例测试结果验证了所提方法的有效性。For modeling and simulation of large industrial enterprises powergrid,modeling based on the grid structure described by graphic files is the most basic and critical step.In order to improve the efficiency of simulation modeling and avoid tedious manual work,a novel agile generation method of electromagnetic transient simulation model is proposed.Firstly,a recognition model based on convolutional neural networks is constructed to identify electrical components in graphic files.Secondly,a method for judging the connection relationship between power components is proposed based on vector buffer,which is used to identify the electrical connection relationship.Finally,a computer program written by authors is used to generate the corresponding simulation data file.The simulation results on a test case show that the proposed method is effective.
