| description | In this article, the subject of research is methods for calculating active power losses
in electric power overhead lines, taking into account the temperature dependence
of active resistances. An analytical approach based on the Ferrari method for
calculating the wire temperature and active power losses under conditions of forced
convection is proposed and substantiated in detail. The peculiarity of the approach
is universality, which is expressed in the fact that the developed mathematical model
allows us to consider non-insulated and insulated wires on power transmission lines
from a single position. The results of calculating the temperature and active power
losses by the proposed method, the least squares method and the iterative method
are presented. The high accuracy of the coincidence of the results obtained by
various methods is noted. |
