Abstract

Power supply systems (PSS) of the agro-industrial complex, as well objects located in the areas remote from the networks of electric power systems, sometimes use electric transmission lines (ETLs) that exploit the ground as a conducting part. When currents flow in the ground, it causes electrical safety issues. To solve them, double two wires and earth (TWE) lines can be used. Such lines use special transformers, in which the voltage vectors of the grounded terminals have an angular shift of 180º. Due to this, there are no currents in the ground a symmetrical mode. In the context of digitalization of the electric power industry, creating computer models of such PSSes that adequately simulate stationary modes is of particular relevance. This paper presents the results of studies aimed at the implementation of computer models of power supply systems that incorporate double TWE lines. Constructive diagrams of ETLs with double TWE lines are proposed. Simulation was carried out by means of the Fazonord software package. The simulation results drew us to the following conclusions: in comparison with a double-circuit ETL, a double TWE line can significantly reduce the cost of non-ferrous metal; the asymmetrical design of this ETL causes a decrease in the quality indicators of electricity at its receiving end; in addition, higher power losses are observed; the double TWE line can be implemented on the basis of two or four single-phase shielded cables.
