Power Transformers for Wind Applications. Requirements and Challenges

The aim of this document is to highlight the high number of transformers used in the wind energy sector. Considering the particularities and requirements of wind energy and its locations, for the correct design of transformers manufactured for this sector it is necessary to take into account aspects related to environmental conditions, footprint, weight, load curve, transients of energization or connection to cables up to 100km in length. As a growing industry, it represents an important market for transformer manufacturers, although all these aspects and others developed in the present document must be taken into account in order to produce a transformer according to the needs of the wind generation industry.
