Power transformers are the basic components of a naval power system at the same time as the equipment with the most significant losses. The deforming regime is introduced by the power electronics in the case of ships of static frequency converters, cycloconverters or syncroconverters (variable speed drives) for the control of propulsion motors, etc. The central theme of this paper is the impact of the deforming regime on power and energy losses in the case of electrical transformers on board cruise ships. For this purpose, the analytical model regarding the determination of losses in transformers when operating in deforming regime is presented. In addition to the winding losses, the magnetic and dielectric circuit also includes additional losses due to the deforming regime. At the same time, an analysis was performed regarding the optimal operation management of the power transformers affected by the deforming regime.
