Abstract

The identification of a three-phase load in a three-wire electrical system is considered, provided that the consumed currents are stored as equivalent of load. It is shown that the system of equations for determining the parameters of the identified load is underdeveloped, which does not ensure the uniqueness of the solution. Various ways of defining this system and obtaining a solution using search optimization using the system of computer mathematics MathCAD are proposed. The calculated versions of the found load equivalents and the values of uncompensated reactive power are analyzed. Since the uncompensated powers are relatively small, it seems possible to use any of the variants of the identified load for the practical calculation of the symmetry-compensating device. References 3, figures 4, tables 6.

 

Key words: three-wire electrical system, load equivalent, search optimization, symmetrical-compensating device.
