Abstract

When modeling asymmetric emergency modes, it is necessary to take into account all possible parameters of the simulated elements, such as power lines, transformers, electrical equipment, electrical load, etc. Each parameter affects the calculated model and the values obtained.
This study investigates the modeling of asymmetric emergency modes in electrical power systems, focusing on the influence of various parameters such as power lines, transformers, and electrical loads. Despite extensive research on electrical networks, a knowledge gap persists in the comprehensive assessment of mutual inductive resistances and capacitive line conductivities in emergency scenarios. Using a feeder model, calculations were performed for different emergency conditions, including short circuits, phase breakages, and double-phase faults. Findings indicate that excluding mutual inductive resistances and capacitive conductivities results in deviations of phase currents and voltages, ranging from 1.4% to 45%, depending on fault type and line length. Notably, voltage stabilization in autonomous power sources remains a challenge, requiring improvements in control devices to ensure symmetric voltage conditions. The implications of this research extend to the development of automated transport energy systems and emergency stabilization techniques for agricultural power sources.
