| description | Currently, there is an increase in power flows along power lines. An important task for the development of the power grid complex is to increase the current-carrying capacity of existing power lines. The use of advanced conductors has become a successful technical solution for this purpose. "New generation conductors" are modern conductors that have advanced mechanical and electrical properties and characteristics. Thus, it has become important to have information about the maximum operation temperature and current limits of the overhead line with new conductors. The approximate current-carrying capacity in Amperes is the value of current at which the conductor temperature reaches its maximum permissible value. It determines the maximum current load of overhead power lines. For traditional steelaluminum conductors, there are several methodological approaches to determining the maximum current load. This fact complicates the definition of an approach to calculating the current carrying capacity for advanced conductors. Nevertheless, the general basis of all methodological approaches is the thermal balance of the conductor. The purpose of this article is to assess the possibility of adapting the method of calculating the approximate currentcarrying capacity of traditional conductors to the calculation of advanced conductors. The article deals with advanced conductors of various brands of comparable cross-section with the classic ACSR 240/39. This work provides information about the selected conductors, their characteristics and design features. The paper shows a mathematical model for calculating the approximate current-carrying capacity of a conductor and shows calculating results for selected conductors. According to the results of analysis and calculations, the adaptation of the presented mathematical model is possible if we refine its parameters and coefficients. |
