Development of a method for determining the rational installation location of technical means of symmetry in an electrical complex with the presence of an electric motor load

Abstract

The work is devoted to the development of a methodological approach to correcting the level of supply voltage in the electrical network by developing an algorithmized method for determining the rational installation location of technical means of symmetry in an electrical complex with the presence of an electric motor load. The developed method makes it possible to implement processes aimed at ensuring the effective functioning of the electrical complex with the presence of an electric motor load in conditions of low-quality supply voltage. The proposed method, based on software, provides design procedures for calculating various options for symmetry and choosing the most economically feasible. Attention is focused on the main criteria for evaluating decisions made when designing the location of technical means of symmetry in the electrical complex. The architecture, the main functional features of the application program as a tool for implementing the calculation method are considered. The program ensures the implementation of electrical calculations in the design, modernization and operation of electrical networks. It provides for the construction of schematic diagrams of sections of electrical complexes with installed means of symmetry. The results of experimental studies demonstrating the effectiveness of the developed method in solving problems of voltage symmetry in the supply electrical network are presented. It is obvious that the developed approach, based on the automatic selection of the locations of the means of symmetry depending on the operating conditions of the electric motor load, makes it possible to automate the design procedures for voltage normalization in the electrical network. Provides minimization of voltage asymmetry in the supply electrical network, contributes to improving the operational reliability of low-voltage asynchronous electric motors. The obtained research results and prospects for the application of the developed approach are discussed, both for solving complex design problems and for the economic justification of local design solutions. A detailed analysis and formalization of the results of the study with relevant conclusions were carried out.
