摘　　要：利用ATP-EMTP建立了某实际输电线路架空地线感应电流计算模型,经过仿真结果与实测结果的对比,验证了其可行性。基于这一模型,仿真分析了输电线路的导线电流、导线电流不平衡度、线路长度、档距、导地线的平均高度、导线相间距离和地线间距等因素对架空地线感应电流以及电能损耗的影响,为降低架空地线能量损耗,采取有针对性的防治措施,提供了技术依据。An induced current simulation model was established for overhead ground wire of a real transmission line using ATP-EMTP. The feasibility of the model is verified by comparative analysis of simulation result between actual measurements. Based on the model, the paper simulated impact factors on induced current and energy loss for overhead ground wire, including transmission power, unbalance level of conductor, line length, span of towers, the average height of ground wire and conductor, distance of conductor and ground wire. It provide some technical basis for applying corresponding measures to reduce energy loss of overhead ground wire.
