“…The complexity of implementing this mode of operation of the neutral is due to the fact that the capacitive current changes depending on the network configuration, resonance can be maintained only automatically, using smoothly regulated arc extinguishing reactors and an automatic control system (Danylchenko et al, 2019, Al_Issa et al, 2021, Shevchenko et al, 2020. In the practice of operation, there is an incorrect use of compensation of capacitive currents because the instructions and recommendations for compensation of capacitive currents, set out in Miroshnyk, 2015, Rubanenko et al, 2020), are not followed.…”

The most common types of damage in distribution networks with a voltage of 6-35 kV have been analyzed. It is shown that the majority of them are single-phase circuits, which can cause overvoltages at the point of damage and negatively affect electrical equipment, which can lead to a decrease in economic indicators. The methods of increasing the reliability of distribution networks with a voltage of 6-35 kV have been analyzed. The main attention is focused on the method of increasing reliability due to grounding of the neutral through an arc reactor, the main advantage of which in operation is the continuation of single-phase ground fault operation without disconnection of consumers. A simulation model of the distribution network in single-phase ground fault mode was developed and its main parameters were calculated. The DiGSILENT PowerFactory software complex is used as a simulation environment. A concrete example of parameter calculation when using the proposed simulation model in the DiGSILENT PowerFactory program, which contains 5 overhead and 5 cable power transmission lines with a voltage of 35 kV with a length of 10 to 100 kilometers. The use of this model will make it possible to study transient processes in the mode of single-phase grounding, to prevent emergency situations in distribution networks. The goal of the work ist development of the simulation model of the distribution network in the mode of single-phase circuit to land and the calculation of its basic parameters.
