摘　　要：同杆并架双回线路动态物理模型在同杆并架双回线路相关研究中占有重要地位。文中以同杆并架双回线路共最小互阻抗模拟方法为基础,针对模型建设过程中面临的技术问题进行分析,提出了改进方案,并完成了模型的研制。仿真和动模试验情况表明,新型同杆并架双回线路物理模型与预期线路参数和实际线路参数吻合良好,为同杆并架双回线路故障和保护的研究提供了经济可靠的实验平台。A dynamic physical model for double-circuit transmission lines on the same tower plays an important role in the study of double-circuit transmission lines on the same tower.Based on the minimal mutual impedance sharing principle,the technical problems in its process of construction are analyzed,an improvement scheme is proposed,and the model is developed. Simulation and dynamic physical experiments indicate that the parameters of the novel physical model are in good agreement with the anticipated line parameters and the actual double-circuit transmission lines in use,providing the study of double-circuit transmission lines fault and relay protection with an economical and reliable experimental platform.
