Justification of Ice Melting Power on 10 kV Overhead Power Lines

Abstract

The fuzzy multicriteria model of the ice melting system on radial 10 kV overhead power lines was developed. Three criteria were taken into account: the minimum of reduced annual costs for ice melting system, the minimum of amount of electric energy not provided to consumers during melting, and the minimum of the amount of electricity consumed for the ice melting. The model also takes into account the fuzzy limitation of the permissible ice melting power associated with the uncertainty of weather conditions. Based on the model we justified the value of ice melting power, which should be provided by serial ice melting devices of industrial production, intended for use on radial 10 kV overhead power lines, taking into account the uncertainty of initial data.
