The article is devoted to the issues of choosing the optimal cross-section of cables and their scales for the lines of rural electrical networks by the method of economic intervals for various laws of load growth, taking into account the restrictions on long-term permissible current loads and permissible voltage loss, and a comparison of the load boundary obtained on the optimization model with economic intervals is carried out load.

The possibility of using artificial neural networks of the Matlab mathematical package for predicting the power consumption of objects is considered, the parameters that affect the power consumption are studied.

The article deals with the issues of interconnection of network costs and power quality, in particular voltage deviations. The graphs of the distribution of voltage deviations for electrical receivers are given for two calculated load modes - the highest (100%) and the lowest (25%), corresponding to the choice of wires of 10 and 0.38 kV overhead lines for economic loads and voltage stabilization on 10 kV buses of 35/10 kV RTP at the level of + 5%.
