摘要:

论文研究了采用不同结构的500 kV交流线路与直流线路共走廊时,交流线路对直流线路的干扰,在此基础上分析了共走廊的可行性。首先建立了交直流线路同走廊情况的电磁耦合干扰模型,并采用该模型分别计算了交流线路单回水平排列、单回紧凑型排列和同塔双回布线方式时,其对直流线路电磁耦合干扰的影响,并比较分析了最适合用于交直流共走廊的交流线路形式。结果表明,交流输电线路的排列方式对直流线路的耦合结果有影响。当水平接近距离为40 m时,单回水平排列的常规型交流线路产生的感应电压值为20.719 kV;单回紧凑型排列线路产生的感应电压值为14.7699 kV,相对下降了28.7%;而同塔双回交流线路产生的感应电压值为35.42 kV,相对增加了61%。感应电压值随着距离的增加而衰减,衰减速率由快变慢,逐渐趋近于零。

In the paper the interference between the 500 kV AC transmission lines with different structure and DC transmission line is investigated, and the feasibility to build the AC lines and DC lines in common corridor is analyzed. Based on the theory of conduction coupling, a novel equivalent model to analyze the influence between the parallel DC and AC transmission lines is presented. Calculation for the induced voltage on the DC transmission lines for different arrangement of the AC conductors and different distance between the AC and DC transmission lines were carried out. Results indicate that the inducted voltage of the horizontal arrangement of AC lines is 20.719 kV when the distance between the AC transmission lines and DC transmission lines is 40 m, the inducted voltage of the AC compact trans-mission lines decrease by 28.7%, and the inducted voltage of the AC double circuit transmission lines on the same tower is 35.42 kV, increase by 34.42%. In addition, the induced voltage decreases with the increasing of the distance.
