Abstract
An approach is proposed to control the voltage regimes of distribution electrical networks containing power transformers with noncontact on-load tap changers, which is based on the solution of the multicriteria optimization problem. The structural scheme of the system of automatic control of voltage regimes of distribution electrical networks is developed, which is based on the solution of the problem of multicriteria optimization. A computer simulation model of the automatic control system was developed, through which the stability of the proposed system was studied. The study of the effect of the application of the developed system of automatic control of voltage re-gimes by computer simulation has shown that the application of the developed system of automatic control of voltage regimes of distribu-tion electrical networks, allows, unlike existing ones, to achieve simultaneous reduction of the levels of steady deviation and voltage asymmetry due to phase change transformation transform coefficients according to the developed control law.
