| Summary: | In this paper, there is considered the problem of calculating the
mode of an electrical network with two-way feed, taking into
account the temperature dependence of the active resistances.
The purpose of the article is to analyze the modes of an electrical
grid with and without consideration of the mutual influence of
electro-thermal processes. The simultaneous solution of the
equations of electric and thermal regimes is realized on the basis
of temperature correction in the formation of the Jacobi matrix at
each iteration of the solution of the nodal stress equations. Taking
into account the temperature dependence of the active resistances
allows us to clarify the parameters of the regime of the electric
power system. Based on the results obtained, it follows that when
taking thermal processes into account, the currents, voltage
deviations and power losses in the network are substantially
refined. The greatest degree of refinement takes place when
calculating the losses of active power. |
