'''Power engineering''', also called '''power systems engineering''', is a subfield of [[electrical engineering]] that deals with the generation, transmission, distribution, and utilization of [[electric power]], and the electrical apparatus connected to such systems. Although much of the field is concerned with the problems of [[three-phase electric power|three-phase AC power]] – the standard for large-scale power transmission and distribution across the modern world – a significant fraction of the field is concerned with the conversion between [[rectifier|AC and DC power]] and the development of specialized power systems such as those used in aircraft or for electric railway networks. Power engineering draws the majority of its theoretical base from [[electrical engineering]] and [[mechanical engineering]].
