摘要

针对750 kV同塔双回线路架空地线感应电流及损耗，通过数值仿真研究了光纤复合地线（optical fiber composite overhead ground wire，OPGW）逐塔接地、普通地线分段绝缘、单点接地的架空地线感应电流及损耗关键影响因素及其规律。结果表明：当线路输送容量和运行电压增加，OPGW的感应电流及损耗增加。OPGW的感应电流及损耗与线路长度呈负相关，线路长度减小，地线感应电流及损耗也减小。架空地线感应电流及损耗随着导、地线间距和两回线路水平间距的减少而增加。普通地线的感应电流和变化幅度均很小，电流最大值为1.6 A，造成的损耗小。基于多元拟合分析了多种因素耦合对架空地线感应电流及损耗的影响规律，得到了地线感应电流及损耗的定量计算关联式，为优化输电线路和降低架空地线损耗提供了理论依据。

Abstract

As for the induced current and loss of overhead ground wire in 750 kV double-circuit transmission line on the same tower

the key influencing factors and patterns of induced current and loss of overhead ground wire grounded by optical fiber composite(OPGW)tower by tower

segmented insulation of common ground wire and single point grounding are studied by numerical simulation. The results show that the induced current and loss of OP-GW can increase with the increase of transmission capacity and operating voltage. The induced current and loss of OPGW are negatively correlated with the line length. When the line length decreases

so do the induced current and loss of ground wire. The induced current and loss of overhead ground wire increase with the decrease of the distance between conductor and ground wire as well as the horizontal distance between two circuits. The induced current and variation amplitude of common ground wire are very small

and the maximum current is 1.6 A

resulting in small loss. Based on multivariate fitting

the influence of various factors coupling on the induced current and loss of over-head ground wire is analyzed

and the quantitative calculation correlation of the induced current and loss of over-head ground wire are obtained

which provides a theoretical basis for optimizing transmission lines and reducing the loss of overhead ground wire.
