Existing models of voltage balancing in electric networks were considered. It was found that such models are underinvestigated when using compensatory balancing installations. The proposed model of voltage balancing in electric networks is based on the Frieze theory. The model is suitable when using compensatory balancing installations, including capacitors.
The evaluation of the model compared with existing ones was performed. During the simulation of the voltage balancing process for one electric network unit, voltage asymmetry parameters were obtained, which were by 30% lower than the voltage parameters, obtained using existing methods. During the simulation of the voltage balancing process for two network units, voltage asymmetry parameters were obtained, which were by 10% - 15% lower than the voltage parameters, obtained using existing methods. These simulation results confirm that the obtained model provides a better voltage quality compared with existing voltage balancing models.
