摘　　要：为了解决大规模省级电网电磁暂态仿真效率低下的问题,研究了一种适用于省级电网的电磁暂态实时仿真建模方法。分析了大电网电磁暂态建模难点,通过子系统建模和任务优化方法建立了省级电网模型,对各子网内部进行功率调节,实现了首次功率平衡;基于输电线路模型法原理完成了各子网之间输电线接口的联络,在预设平衡点的基础上,通过在线调节潮流的方法使得所建模型运行在合理平衡点上。为验证该方法的有效性,基于自主研发的实时仿真器(universal real-time experimental platform,UREP-300)对某新型省级电网进行实时仿真。仿真结果表明,所提方法能提高仿真效率,扩大了系统的仿真规模,减小了实时仿真机的计算负担,可为各类大规模系统的仿真与建模提供一种参考。To address the low efficiency of electromagnetic transient simulation of large-scale provincial power grids,a real-time electromagnetic transient simulation modeling method suitable for the provincial power grid is studied.First,the difficulty of electromagnetic transient modeling of a large power grid is analyzed,and a provincial power grid model is established by subsystem modeling and task optimization,and power regulation is carried out within each subsystem to achieve power balance for the first time.Based on the principle of transmission line model,the connection of transmission line interfaces between subsystems is completed.On the basis of the preset balance point,the power flow is adjusted online to make the model run at a reasonable balance point.To verify the effectiveness of the proposed method,a real-time simulation of a new-type provincial power grid is carried out based on the self-developed universal Real-Time experimental platform(UREP-300).The results show that the proposed method can improve the simulation efficiency,expand the simulation scale of the system,reduce the computational burden of the real-time simulator,and provide a reference for the simulation and modeling of various large-scale systems.
