摘要/Abstract

摘要： 临近1 000 kV 同塔双回交流输电线路架设输电线路，挂接地线是防止感应电危害施工人员安全的有效措施。为了确定施工中输电线路接地线感应电流分布和接地线拆除方案，基于ATP-EMTP电磁暂态程序，建立了±1 000 kV 吉泉直流输电线路长距离并行同塔双回1 000 kV 交流输电线路的模型。计算了施工中直流线路中的感应电流，分析了线间距离、并行长度、线路高度和土壤电阻率等因素对感应电流的影响。最后，针对地线的拆除顺序提出了相应的接地线拆除方案。

Abstract: Transmission lines with certain length are erected nearby the 1 000 kV double-circuit AC transmission lines, and the usage of grounding wires is an effective measure to prevent the safety of the construction personnel from being injured by inductive electricity. It aims at analyzing the induced current distribution of the grounding wires in the construction and the demolition scheme of grounding wires. Based on the ATP-EMTP electromagnetic transient program, a model of the long distance ±1 100 kV Jiquan DC transmission lines parallel with double circuits on the same tower of 1 000 kV AC transmission lines is established. The induced currents in the DC transmission lines in the construction are calculated. The influence of the inter line distance, parallel length, line height and soil resistivity on the induced currents are analyzed. Finally, the corresponding grounding wire removal plan for the demolition sequence of ground wires is proposed.

Key words: UHVDC, transmission line, grounding wire, induced current, ground wire demolition, EMTP
