Abstract

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.
