分析了微地形对输电线路舞动的影响，建立了输电导线动力学模型及相应微地形下的流场模型。对存在微地形影响的某实际输电线路进行了动力学仿真分析，仿真结果与实际观察一致。对比分析了有、无微地形影响的仿真结果，发现微地形对于输电线路舞动的振型、振幅等特征具有显著影响。

A flow field model and a dynamic model of transmission line are introduced based on the analysis of micro-terrain effect on transmission line galloping. The dynamic simulation analysis was carried out for a transmission line with the consideration of micro-terrain influence, of which result was consistent with the practical observation. The results show that micro-terrain has significant effect on the transmission lines galloping characteristics of vibration mode and amplitude, with the comparative analysis of the simulation results with and without micro-terrain effect.
