Intelligent voltage regulation system in the distribution electrical network based on fuzzy logic

Abstract

The paper considers the issues of voltage regulation in the distribution network. The possibility of using fuzzy logic implemented in a fuzzy controller for voltage control is shown. The purpose of the study: to increase the resource of switches of voltage regulators of power transformers when controlling voltage and reactive power modes of distribution electrical networks. Subject of research: the introduction of a fuzzy controller in the voltage level control system in the distribution electrical network. Methods and objects of research: the study was conducted using numerical simulation, fuzzy logic methods. The objects of the study were the distribution electrical network as well as power transformers equipped with voltage regulators, adjustable compensating devices working together under the control of a fuzzy controller. Results of research: based on the conducted experiments, it was shown that the joint use of voltage regulation means (transformers, compensating devices) in the distribution electrical network when controlling a fuzzy controller allows to increase the resource and extend the service life of transformer switching devices.
