Power Transformer Temperature Evaluation for Overloading Conditions

Dynamic Network Rating for Low Carbon Distribution Network Operation—A U.K. Application

“…Cost savings and deferred replacement of transformers subject to loading constraints could be achieved if transformers can be operated beyond their nameplate ratings for certain periods. Other published work to date has focused on dealing with overloading, i.e., loading above the nameplate rating [5], or highly fluctuating load profiles, such as for wind turbine transformers [6].…”

Thermal modelling for dynamic transformer rating in low carbon distribution network operation

“…The original idea is to cope with overloading, i.e. loading above the nameplate rating [4,5], or highly fluctuating load profiles, such as for wind turbine transformers [6]. The main aim of a real time application is to take advantage of environmental impacts, e.g.…”

Smart demand side management of low-voltage distribution networks using multi-objective decision making

“…However, this rating limit can also be made dynamic based on a transformer thermal model which considers the transformer rating, the overload magnitude and period, and the ambient temperature [27]. This would generally allow a greater load before limiting, while still maintaining the transformer overload protection.…”
