摘　　要：目前超高压架空输电线路普通地线基本上按分段绝缘,光纤复合架空地线按逐基杆塔接地运行。应用EMTP程序对750 kV官东Ⅰ线架空地线的感应电压和环流进行仿真计算,并分析了导线负荷、普通架空地线长度、土壤电阻率和线路短路电流对普通架空地线的感应电压和光纤复合架空地线环流的影响。Currently common ground wire of EHV transmission lines is grounded by graded insulation and OPGW is grounded by stem tower. Inducted voltage and circulation on overhead ground wire of 750 kV Guandong I line is simulated by EMTP program. The influence of wire load, general overhead ground wire length, soil resistivity and short-circuit current on the inducted voltage of common ground wire and the circulation of OPGW is analyzed.
