摘　　要：我国电力工程领域及其相关技术发展迅速,输电网架容量日益增大,高压输电线路架设两根架空地线是提高输电线路安全稳定运行的重要技术措施。但双架空地线的设计在电能损耗方面存一定问题,当每个档距间的地线逐塔接地时,架空地线间或架空地线与地之间会形成感应环流,造成较大的电能损耗。因此,随着双架空地线应用的推行,其并发问题得到越来越多的关注,已成为当代电网建设的重要研究课题。With the rapid development of electric power engineering and related technologies in China,the capacity of transmission network is increasing day by day.It is an important technical measure to set up two overhead ground wires on high-voltage transmission lines to improve the safe and stable operation of transmission lines.However,there are some problems in the design of double overhead ground wires.When the ground wires of each span are grounded tower by tower,inductive circulating current will be formed between overhead ground wires or between overhead ground wires and ground,resulting in large power loss.Therefore,with the implementation of the application of double overhead ground wire,its concurrent problem has been paid more and more attention,and has become an important research topic of contemporary power grid construction.
