Abstract
The article considers the possibility of determining the source of higher harmonics of currents and voltages in the electrical network in the directions of power of the respective components. The research purpose is evaluating the effectiveness of theoretical methods, computer modeling of a fragment of the electrical network and electrical load receivers operating in parallel. Different combinations of active, reactive and nonlinear loading are investigated. Larionov's scheme was used as a nonlinear load. According to the results of the study, conclusions were made about the effectiveness of the method used. Thus, in particular, in the case of parallel operation of nonlinear and mixed active-nonlinear load, the source of higher harmonics is determined incorrectly. Suggestions for ways to improve the algorithm are made.
