Abstract
When developing an integrated program that can be used in production to calculate and analyze energy losses in the electric distribution network, unique mathematical modeling suited to the specific electric distribution network, its structure, organization, characteristics, and scope of service is applied, along with linear and nonlinear calculation model methods. There are direct methods and mathematical-statistical methods to determine energy losses in distribution networks through calculations. It is necessary to correctly select the mathematical model for calculation, the scale of the model, and composite calculation methods, and in some cases, develop new ones, design algorithms, and create software. The method of determining electric power loss using the duration of losses based on the steady-state calculation of the electrical distribution network is highly accurate, but it has the drawback of requiring a large amount of primary data and monthly mode measurements of each substation in the calculations. Therefore, in this study, a simple method was used to determine electric power loss using the measurement values of meters installed at the head of the distribution network, employing a single-line, single-transformer equivalent model. In this method, when performing the calculation, a load shape coefficient was calculated instead of using the duration of the loss. This article discusses programs developed to determine electric power loss in the distribution network in this direction and using them to perform calculations for reducing power loss in the short term.
