ANALYSIS OF PARAMETERS SERIES OF WIRE CROSS-SECTIONS FOR OVERHEAD POWER LINE DESIGN

SUMMARY

In the analysis of the parameters series of wire cross-sections for the overhead power line design taking into account their development prospects, the author solved the following tasks. The study of the existing parameter, which characterizes and determines the optimization option of the technical and economic model for the design of overhead lines, which allowed showing the unreasonableness of using the economic current density as the basic optimization parameter of the technical and economic model of overhead lines is performed. The wire cross-section as the basic optimization parameter of the technical and economic model of overhead lines is proposed. The scale growth factor of the parameters series of wire cross-sections is obtained by the criteria-based method, which allowed developing an optimum scale of wire cross-sections. Estimation of the statistical characteristics of the distribution of the relative value of wire cross-sections is carried out. The introduced hypothesis of a log-normal distribution law of the current density is tested using the Pearson's chi-squared test for finding the relationship of relative variation of the initial information on the scale growth factor of wire cross-sections. The effect of the optimum scale of wire cross-sections on the regulations of reconstruction, which is due to the load rate and growth variations in the power grid is determined.
