输电线路架空地线逐基接地时存在感应电流和电能损耗，目前对架空地线感应电流数值大小和影响机制的研究较少，对架空地线损耗问题重视不足。以某双回线路为例进行了架空地线感应电流现场实测和 ATP-EMTP 数值计算，计算了不同线路长度、档距、导地线型号、导地线空间布置等输电线路结构参数对架空地线感应电流和电能损耗的影响。计算结果表明：线路起始段（长度小于9 km）时架空地线感应电流随着线路长度增大而增大；不同档距和导线型号通过导线弧垂变化影响架空地线感应电流和电能损耗；地线感应电流和电能损耗随着导地线空间距离增大而减小，随导地线高度变化明显，导线相间距和地线间距影响小。

Induced current and energy loss characteristics and influencing mechanismof overhead ground wires grounded at each tower are lack of research. Induced current of overhead ground wires in a double-circuit transmission line is measured and calculated with ATP-EMTP. Furthermore, the influence of length of transmission line, spans, type of conductor wires and ground wires and space location of conductor wires and ground wires on induced current and energy loss is carried out. It shows that induced current increases with length of transmission line which is less than 9 km. Different spans and types of conductor wires resort to the sag to change induced current and energy loss. The more distance of conductor wires and ground wires is, the less induced current and energy loss are, which is apparently changed with average height of conductor wires and ground wires but affected little by distance of phase wires or ground wires.

架空输电线路是将不同地区的发电厂、变电站、负荷点连接起来，起输送或交换电能作用的线路。由于架空线路暴露在大气环境中，易受到雷电袭击、雨淋、湿雾以及自然和工业污秽等造成停电事故。因此，加强架空输电线路的运行维护具有重要的意义。

Overhead transmission line is connecting the power plant, transformer substation, load point in different regions, designed for conveyance or exchange of electric energy. Bec- ause the overhead line is exposed to the atmosphere, it is often caused blackouts due to lightning, rain, wet fog and natural and industrial polution. Therefore, it is of important significa- nce to strengthen the maintenance operation of overhead tran- smission lines.
