Abstract :
This paper describes the impact of cooling modes of dry-type transformers as per standard IEC 60076-11 in a substation designed as per IEC 62271-202. This voltage and frequency transformer substation is designed for onshore grid connection for ships at berth. For this reason, the service conditions adopted as per standards IEC 60721-3-4 and IEC 60721-2-5 are a key factor in the choice of cooling mode for this prefabricated port installation. The use of numerical simulations is essential for guiding choices towards the most reliable overall solution.
