Abstract

Abstract: With the vigorous development of power transmission technology in China, parallel AC and DC transmission lines in the same corridor is also expanding. The inductive electricity between the lines is harmful to the system, and much attention should be paid to it. In this paper, the principle of line induced voltage is described, and the EMTP electromagnetic transient analysis software is used to calculate the induced voltage of the 1000 kV transmission line to the new transmission line. The influence of the distance between the transmission lines, the parallel length and the height of the transmission line on the induced voltage is analyzed. The waveform of the induced voltage is simulated, and the simulation results agree well with the theoretical analysis.
