Abstract
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.
Highlights
Electrical distribution networks for agricultural purposes are characterized by a constant increase in loads
To select the cross-sections of cable power lines, until now, the economic current density is widely used, which does not meet the condition of the minimum total costs [1-8]
The boundaries of economic intervals for adjacent sections for the case that does not take into account the dynamics of load growth are determined [910]: гр =
Summary
Electrical distribution networks for agricultural purposes are characterized by a constant increase in loads. It became necessary to determine the economic load intervals for the selection of cable cross-sections and the solution of related problems, taking into account the dynamics of load growth.
