摘要：
The structural and operational factors influencing the asymmetrical work of steel arc furnaces in the power system are presented. In order to map the asymmetry of network load using a system of three electric arcs, the Pentegov mathematical model with different static-voltage characteristics was used. In addition, the asymmetry of the high-current path was taken into account by increasing the phase impedances under conditions of symmetrical arcing load. The simulation method examined the effect of load asymmetry on the values of asymmetry indicators, determined on the primary and secondary side of the furnace transformer.
