The thesis is devoted to the problem of increasing the accuracy of calculations of technical losses of electric power in overhead power lines with a voltage of 6-35 kV by taking into account climatic factors. The model of thermal processes in the wires of overhead power lines has been improved by taking into account meteorological factors. Approaches to calculation of electric power losses in overhead transmission lines are analyzed and investigated. The analysis of approaches to calculating the energy losses in air power lines, after checking the adequacy of the results obtained, showed the advisability of applying the approach in which the energy losses should be calculated taking into account the average monthly air temperature for a given region. For more accurate forecasting and calculation of losses, it is recommended to calculate losses daily using the average daily temperature and other weather data. The proposed approach is more accurate than the officially adopted approach. For the first time, the heat transfer coefficients for the electric power transmission lines have been calculated, calculated and proposed to include heat transfer coefficients taking into account the influence of precipitation (rain, snow). The basic heat balance equation for the steady-state thermal regime for wires of overhead power transmission lines has been improved taking into account the recommendations, the proposed approach to temperature selection and the calculated heat transfer coefficients at atmospheric precipitation on the wire surface. The model of a neural network for calculation and forecasting of technical losses of electric power in overhead power lines of 6-35 kV voltage has been developed and proposed for use.
