摘　　要：提出了电力运行类数字孪生系统的一种实现方案,介绍了电力运行类数字孪生系统的特征,搭建了稳态逆向数学模型。基于上述模型的孪生系统在同步态实时跟踪真实系统,在离线运行态准确预测操作的未来趋势,弥补了机理建模与真实系统无关联和大数据分析无法预测未知操作趋势的不足。An implementation scheme of the digital twin system for electric power system operation is put forword,the characteristics of the digital twin system are introduced,and a steady-state reverse mathematical model is established.The digital twin system based on the model can track the real system in real time under the synchronous state and predict the future trend of operation accurately under the off line operation state,which makes up for the deficiency that the mechanism modeling is not related to the real system and the big data analysis can not predict the unknown operation trend.
