Simulation and Analysis of Induced Voltage and Induced Current on Overhead Ground Wire of Jindongnan-Nanyang-Jingmen 1000kV UHV AC Transmission Line
With continuous development of UHV transmission technology and increasing of UHV transmission project,UHV will be one of the main power transmissions in China.Chinas first UHV single-circuit transmission line Jindongnan-Nanyang-Jingmen AC transmission project has been completed and put into operation successfully.Due to the spatial location of UHV transmission line and overhead ground wire on it,induced voltage and induced current generate in the ground line through electromagnetic and electrostatic coupling by transmission circuit.Induced voltage and induced current on overhead ground wire of Jindongnan-Nanyang-Jingmen 1000kV AC line are calculated by EMTP in this paper.Besides,factors such as distance between conductor wire and ground wire,transmission power and segment length of insulated ground wire，that affect induced voltage and induced current on overhead ground wire are analyzed in this paper.This paper can provide a reference for many aspects of UHV transmission line,such as maintenance work,live line work,and rational utilization of induced voltage and induced current.
