Introduction to Electrical Engineering is the first specialized course for our freshmen. As a freshman, when I first came into contact with this course, I felt strange and even a little scared: What if I didn't learn in high school? What if the specialized courses are so difficult? In addition to strangeness, there are some expectations and some excitement: learning professional courses! Finally out of the clutches of language! When it came to class, the fact is that it didn't let me down! Although it didn't teach me a deep understanding of knowledge, it gave me a general concept and let me know what I should do and what I can do in four years. Perhaps this is also the purpose of the introductory course.
Through a stage of study, I also have some simple knowledge and understanding of electrical engineering, mainly including the following contents. Generally speaking, the specialty of electrical engineering and automation has many directions. The undergraduate course mainly includes: motor and its control, power system and its automation, high voltage and insulation technology, industrial automation, electrical technology and so on. The master's degree mainly includes: electrical machinery and appliances, power system and its automation, high voltage and insulation technology, power electronics and power transmission, electrical theory and new technology. With the progress of science and technology, the connotation of specialty will also change. The major of electrical engineering should also keep pace with the times, and mainly integrate with other disciplines, such as information science, automation science, computer science, electronic science, energy science, materials science, etc., in order to develop itself. Students majoring in electrical engineering should learn more automation and information technology in the future in order to keep up with the times.
The innovation and development of knowledge requires talents not only to have rich scientific and cultural knowledge, but also to have strong innovative spirit and ability, as well as good cooperative spirit and organizational management ability. Only in this way can they adapt to the requirements of the development of the times. Therefore, it has become a common understanding to broaden the professional caliber and reduce the teaching hours of professional courses.
The present era is an era of "knowledge explosion", and the speed of knowledge generation and updating is very fast. The new knowledge learned a few years ago may be out of date now. The same is true of electrical engineering. We cannot expect to learn all the professional knowledge of electrical engineering in four years. But it is really necessary to know the general situation of electrical engineering as soon as possible, which can help students master the basic technical context of electrical engineering as soon as possible and lay a solid foundation for further study of this major. Therefore, how to design one's career according to one's own interests, how to choose one's major and professional direction according to one's own hobbies, and how to choose the most suitable professional courses according to one's own specialties have become more and more concerned by freshmen, and they are also eager to know the general situation of their major as soon as possible. This textbook "Introduction to Electrical Engineering" gives a comprehensive introduction to the development history, professional characteristics, professional knowledge structure and application fields of electrical engineering, which has played a guiding role in my major, professional direction selection and course selection. At the same time, it broadened my horizons.
The following are some basic information about electrical engineering and its automation that I have mastered initially. The specialty of electrical engineering and automation belongs to the discipline of electrical engineering. This major aims to cultivate advanced compound applied talents who can adapt to the needs of socialist market economy and electrical engineering and have the ability of planning, research, development, design, operation and management in the field of electrical engineering.
In short, we should be safe when we come, no matter how difficult our major is to learn, no matter how broad our professional employment prospects are, no matter how difficult it is to take the postgraduate entrance examination, it is king to learn every course, whether it is a basic course or a professional course, and learn how to use it well, so as to be invincible in the complicated social employment environment. Of course, it is also important to cultivate practical ability and innovative ability in learning. The talents needed by the society must be available innovative talents, not bookworms who can only take exams. I will stick to my dream to become a senior electrical engineer for my life, for my ideal, and for my motherland's power industry not to lag behind any country.
