description: The purpose of this work is to study methods for calculating the PVN presented in two standards - domestic GOST R 52565-2006 and foreign IEC (IEC) 62271-100. The influence of the configuration of the U-shaped equivalent circuit of the power line on the parameters of the power supply line - its initial speed and its maximum value - is also considered. The work was carried out on the basis of MATLAB SIMULINK by designing and constructing an electrical circuit for calculating the PVP and modeling its curve. The circuit parameters were calculated according to data from the standards in question. Equivalent circuits for power lines with different numbers of P-elements were collected in order to select a configuration that would most objectively reflect transient processes of voltage restoration at the contacts of a high-voltage circuit breaker. As a result of the work, an analysis and comparison of PVN curves for lines with different numbers of P-elements was carried out. Analyzing the results, we can say that when choosing a standard for calculating the PVN, it is worth taking GOST 52565-2006, since it is stricter regarding the calculation method and the normalized PVN characteristic constructed according to this standard has a peak of 13 kV more than the curve plotted according to the foreign IEC standard. And also, that in 110-750 kV networks, lines with 3-4 P-elements showed 5% more PVN. This allows you to include a margin in the calculations.
