摘　　要：风光新能源场站在构建新型电力系统中占据重要地位,其电磁暂态实时仿真愈发受到关注。由于新能源场站网络解算十分复杂,串行逻辑冗长,难以在目前开发较为成熟的多核CPU仿真机上实时仿真。因此提出了一种基于多核CPU的风光新能源场站全拓扑实时仿真建模方法。该方法基于电网络等效原理,建立发电单元四端子等效模型,依据该模型的仿真流程设计适用于多核CPU的并行仿真架构,实现新能源场站的实时仿真。所建场站模型利用内部电压的计算可保留高精度的全拓扑信息,同时通过降阶有效降低网络解算资源占用,缩短串行逻辑。经仿真测试,相较于RTDS模型,该方法所建模型在保证精度误差小于4%的同时可实时仿真的场站规模扩大3倍,有效降低实时仿真硬件成本。Wind farms and photovoltaic new energy stations are important in constructing new power system,and their electromagnetic transient real-time simulations attract more and more attentions.Due to the complexity of the network solution and the lengthy serial logic for the new energy station,it is difficult to achieve real-time simulation on the currently mature multi-core CPU simulator.A full-topology real-time simulation modeling method for the wind farm and photovoltaic(PV)power station based on multi-core CPU is proposed.Based on the principle of electrical network equivalence,this method establishes a four-terminal equivalent model of power units,and designs a parallel simulation architecture suitable for the multi-core CPU according to the simulation process of this model to realize real-time simulation of new energy stations.The proposed station model uses the calcula⁃tion for internal voltage to retain high-precision full topological information,and at the same time effectively reduces the network solution resource occupation and shortens the serial logic by reducing the order.After simulation tests,compared with the RTDS model,the model built by this method not only ensures that the accuracy error is less than 4%,but also enables a threefold increase in the scale of the power station that can be simulated in real time,effectively reducing the hardware cost of real-time simulation.
