Abstract
Abstract. A method is proposed for calculating the initial value of the periodic term of the short- circuit strength of a dual-circuit overhead transmission line using multiphase replacement circuits. The method takes into account the electromagnetic connections between the wires of the dual-circuit overhead line and the ground to transient modes. The calculation model will allow to take into account the influence of the internal properties of the dual-circuit overhead line when calculating the three-phase short-circuit currents at the design stage, which will significantly improve the accuracy of the choice of relay protection settings and line automation. The model was tested in Matlab Simulink.
