Electromagnetic transient modeling method and system for alternating current power grid

The invention discloses an electromagnetic transient modeling method and system for an alternating-current power grid. The method comprises the steps: converting alternating-current power grid data stored in a target data file into an electromagnetic transient initial model on PSCAD software through a tool; adjusting a load model in the electromagnetic transient initial model; and obtaining an electromagnetic transient final model based on the adjusted electromagnetic transient initial model, thereby improving the technical problems of low modeling efficiency and relatively high error rate in the prior art that the electromagnetic transient model is built manually. 本申请公开了一种交流电网的电磁暂态建模方法和系统，方法包括：通过工具将保存在目标数据文件中的交流电网数据转换成PSCAD软件上的电磁暂态初始模型；对电磁暂态初始模型中的负荷模型进行调整；基于调整后的电磁暂态初始模型获取电磁暂态最终模型，改善了现有技术通过全手动搭建电磁暂态模型，存在的建模效率低和出错率较高的技术问题。
