Efecto de la adquisición, considerando la capitalización de pérdidas, en la eficiencia de flotas de transformadores de potencia

Abstract

 In the current context where the objective is the reduction  of the world energy consumption, it has been published  the Commission Regulation No 548 of 21 May 2014 on  Implementing Directive 2009/125/EC of the European  Parliament with regard to small, medium and large power  transformers. This regulation establishes minimum performance  values for each size and type of machine. The performance  considered in this document corresponds to the maximum  value developed for each transformer. This parameter is  independent of the loading regime and helps to carry out  performance comparisons in the operating point of minimal  losses. On the other hand, some Transmission System Operators  and Utilities consider the cost of losses when purchasing new  transformers, this is known as capitalization of losses. This  article has studied the effect of losses capitalization on the  performance of power transformer fleets. For this objective, the  losses of a large population of European power transformers  have been considered. The machines analyzed are classified by  the regulation as liquid immersed large power transformers.  Moreover, the study takes into account machines with power  higher than 100MVA. This European legislation proposes the  same performance limits for any transformer exceeding this  power.
