Classical and solid-state tap-changers of HV/MV regulating transformers and their regulators
Main Article Content
Abstract
The paper presents the designs of classic and solid-state tap-changers for HV/MV regulating transformers. A simulation model was designed to assess the quality of voltage regulation with an on-load tap-changer. Disruption in this model is represented by a change in the demand and supply voltage of the transformer. Based on simulation studies, the paper presents the comparative characteristics of classic and solid-state tap-changers. The effect of replacing the classical tap-changer switch with a solid-state one on the regulator synthesis was also studied. Based on the analyses above new options of regulation with solid-state tap-changers have been formulated. The purpose of this paper is to determine the requirements for this new type of regulator for solid-state tap-changers and possible criteria for the operation of this control mechanism.
