Abstract

This paper aims to measure the impact of the climatic conditions, the oil thermal parameters, and the effect of the on-grid photovoltaic (PV) system on the transformer thermal performance for two different regional climatic conditions. Then, it's aimed to enhance the thermal performance by inserting an on-grid PV system. The climatic conditions have a major role in measuring the transformer's loading ability. Loading ability has a thermal limit, which is described as the winding hottest spot temperature (HST) as well as top of oil temperature (TOT). This loading ability was governed by the load profile and the environment's temperature; if they exceeded the limit, the transformer would deteriorate. So, to tackle this issue, climatic conditions are modeled on the principle of daily ambient temperature for mineral oil and oil natural air natural (ON AN) cooling type transformers. This paper concludes that using a PV system in parallel with the transformer to supply the same loads will improve the transformer's thermal performance by 22%.
