　　智能配电系统暂态仿真扩展了传统电力系统电磁暂态仿真的研究对象与范畴，但同时也限制了仿真计算的规模与速度。为此，以 Krylov 子空间线性系统化简理论为基础，实现了对具有线性系统特征的大规模配电网络模型的整体降维化简。仿真结果表明，根据仿真需要对研究重点以外的配电网络进行合理化简，可在满足精度要求的前提下有效降低智能配电系统暂态仿真模型规模，极大提升系统整体的仿真速度。

The transient simulation of smart distribution grids extends the study category of traditional electromagnetic transient simulation, but at the same time limits the simulation speed and model scale. For this reason, a model order reduction (MOR) method is proposed based on Krylov subspace theory for large-scale linear distribution grids, which possess the features of linear system. Simulations are performed and lead to the conclusion that the model scale of smart distribution systems may be decreased effectively with appropriate MOR of the distribution grid, and then the simulation efficiency of overall smart distribution grids may be improved significantly.
