摘　　要：为了研究同塔双回直流线路感应电压特性,通过COMSOL有限元仿真软件依托安徽省改造完成的直流线路建立了±500 kV/±800 kV同塔双回直流输电线路模型并进行仿真研究。仿真结果表明:电晕所产生的离子流场是停运线路附近产生感应电压的重要因素,雨天以及大风对感应电压亦有较大影响,海拔高度对感应电压影响较小。In order to study the induced voltage characteristics of double-circuit DC transmission lines on the same tower,a±500 kV/±800 kV double-circuit DC transmission line model on the same tower was established and simulated by using COMSOL finite element simulation software and relying on the DC lines renovated in Anhui province.The simulation results show that the ion flow field generated by corona is an important factor for the induced voltage generated by the shutdown line.Rainy days and strong winds also have a great impact on the induced voltage,while the altitude has a small impact on the induced voltage.
