1.    Introduction to subject

The subjectof electric power engineering plays a very significant role in sciencedevelopment. The application of electric power engineering involves industry,agriculture, transportation, science, education, defense, human life and et al.It effects the economy development extensively. So the electrification has beenregarded as the greatest achievement of engineering technology in the 20thcentury. On the promotion of demand and interdiscipline, the subject ofelectric power engineering is presenting the active development trends. Themain trends are as following:

(1)The generation, transmission, distribution and application of electricity hasbeen developed to effectiveness, flexibility, safety, reliability, environmentfriendly and resource conservation. The current research focuses on theeffective transition and application of renewable energy such as wind and solarenergy.

(2) The new appearance, theory, model andapplication of the interaction of electromagnetic field and materials havebecome the important basis and innovative resources, especially the applicationof extraordinary environment and extreme situation.

(3)With the penetration of informationtechnology, the Internet technology, intelligence technology, nanometertechnology and biology technology promote the overlap of the subject ofelectric power engineering that brings new energy to the development ofelectric power engineering.

(4)The development of new electrical materials advanced the development of new electricaldevice, equipment and system.
