The impact of power transformer in a low-voltage network on voltage profiles with a large generation of microsources

摘要

The purpose of the article is to determine the impact of micro-installations, mainly photovoltaic (PV) sources on the quality parameters of electricity. The analysis is aimed at improving voltage profiles in low-voltage networks with a high concentration of micro-sources. In this type of installations, there is a risk of voltage increase beyond the allowable parameters. The article presents the possibility of levelling voltage profiles using a 15/0.4 kV transformer.
