| 摘 要： | 对1 000 kV淮南－皖南同塔双回线路参数、母线电压和发电机电流的不平衡度进行了分析，研究中考虑了2种常用的换位方式，对不同换位方式下的潜供电流和恢复电压、感应电压和感应电流进行了比较。结果表明，从降低母线电压和发电机电流不平衡度的角度来看，采用换位方式2较好；从减少潜供电流和感应电压的角度来看，采用换位方式1更佳。在满足国标要求的前提下，为了限制线路的潜供电流、感应电压和感应电流，推荐淮皖线采用换位方式1。

| Abstract: | The unbalance factors of line parameters,bus voltages and generator currents of 1 000 kV power double-circuit transmission line on the same tower from Huainan to Wannan are analyzed.Two kinds of transposing modes in common use are taken into account.The secondary-arc currents and recovery voltages,induced voltages and induced currents under different transposing modes are compared.Comparison results show that from the viewpoint of reducing unbalance factors of bus voltage and generator currents,the transpos... |
