How to systematically study the course of electrical automation, or this major?

In view of the undergraduate study, I think it is best to divide it into three stages: the first stage: studying "mathematics" and circuits seriously in the basic stage to lay the foundation for the second stage of study. The second stage: professional knowledge learning stage: learning all professional courses required by university courses such as high voltage technology, power system analysis and relay protection principle. The third stage: choose a development direction and study deeply in the stage of knowledge upgrading. The following is the specific analysis of each stage: the first stage: the basic stage (freshman and sophomore): the high number: it is the most important, and it is extremely important for the postgraduate entrance examination and future study. It can be said that mathematics is the basis of studying electrical engineering. If you are not good at math, or if you don't learn math well in your freshman year, you will feel very painful in the later courses. Linear algebra: It is almost enough to be familiar with the definition, basic operation and several decomposition of matrix, and it is not difficult to use this knowledge in the future. Complex function: focus on Fourier decomposition and Labourasse transformation. (According to different schools, the courses may be different. My freshman year is basically the basis of public education, mainly several mathematics. ) Circuit: It can be said that circuit is the basis of learning this course. If you don't learn well, the following courses are also difficult to learn. The knowledge of circuit will be used in any professional course in the future. Circuit recommended by Higher Education Press, Qiu Guanyuan, editor-in-chief of Circuit (Douban) College Physics: Personally, I don't think it is necessary to study both volumes (but the school must arrange it this way). The focus of our major is electromagnetism, and learning electromagnetism well is to lay the foundation for electrical engineering. Digital electricity and analog electricity: professional basic courses seem to be of general use, but in fact, it is very favorable to learn these two courses well if you want to study electrical engineering in depth. Because the further development of power system is the study of power electronics, power electronics requires these two courses to have a solid foundation. Electrical engineering: a professional course in the true sense. According to my senior, the focus of this year's Southern Network Examination is electrical engineering. I recommend Yan's Electrical Engineering and Jiaotong University Press or Tsinghua University's Electrical Engineering Jiaotong University (Douban) and Tsinghua's Electrical Engineering (Douban). My school uses China Electric Power Press. Personally, I think this motor of Electric Power Publishing House is not as popular as that of Xi Jiaotong University, and some details are not enough. ) Xi Jiaotong University Electrical Engineering Teaching Video: Yan 73 Lecture on Electrical Engineering of Jiaotong University 1.82 GB_ Free high-speed download of professional knowledge Learning stage: (junior year) Power system analysis: basically it can be said to be the core course in the direction of strong electricity. Power System Analysis (Volume I) (Douban) published by Huazhong University of Science and Technology and edited by He Yangzan and Wen Zengyin is recommended. The main contents include rectification (AC → DC), temporary wave (DC → DC), inverter (DC → AC) and frequency conversion (AC → AC). Therefore, high-voltage transmission involves the contents inside. In fact, even the mobile phone chargers we use now are realized by power electronics technology. I recommend Power Electronics Technology (Douban) edited by Wang Zhaoan, and Machinery Industry Press (I have to vomit how obscure and tearful the books compiled by my own teachers in our school are). Power plant electrical part: I think this is the most practical course, and it is also a favorite aspect of power grid interview, because it involves our future work, electrical design, operation and maintenance of electrical equipment, and selection of electrical equipment. Main recommendation: Power Plant Electrical Part (Douban), Fourth Edition. The second edition of Power Plant Electrical Part (Douban) supplements the video teaching course of Xi Jiaotong University: Power Plant Electrical Part of Xi Jiaotong University. Rar_ free high-speed download relay protection principle: mainly for the protection principle of power grid: lines, power transformers, generators, buses, etc. The conditions of safety, reliability and economy are analyzed in detail. Principles of Power System Relay Protection (Douban) 72 Lecture on Principles of Power System Relay Protection of Xi Jiaotong University, Harbin Institute of Technology. Senior high-voltage technology and computer protection rar_ free high-speed download will not be mentioned one by one, but the most important thing is power system analysis, power plant electrical part, relay protection principle. In addition, two websites of Baidu network disk and teaching videos of some courses are attached: Baidu cloud network disk sharing-morning wind 5 173 Xi, microcomputer principle and interface technology of Anjjiaotong University.

(Personally, I think there are two choices:) You have learned the professional courses required by the school well and have spare capacity. You can choose a local direction, such as high voltage transmission, power grid frequency modulation, reactive power compensation and other directions for in-depth research. Personally, I don't advocate going to the library to borrow a bunch of books on high-voltage technology and electrical architecture after studying the professional courses required by the school, and then eating them one by one. This is often ineffective. You forget a book after learning it. You can try to study the graduation design topic of senior year, and it will be much better to borrow books when doing curriculum design. There is no absolute study time at these stages. For example, if you learn computer language, you can learn it from freshman year. According to everyone's learning ability and energy, it is enough to arrange these three stages of learning reasonably. About the software and hardware of this major: Hardware: There are few things in this field, and there are not many experimental equipment because of the danger. Key experiments: circuit experiment, electrician experiment, electrician training and digital electrical simulation experiment. Software: MATLAB, PSASP, BPS, CAD, C language, which softwares are commonly used in electrical engineering and automation? The SIMULINK simulation module in MATLAB is our most commonly used simulation tool, which can simulate power systems and power electronic devices. MATLAB/SIMULINK Simulation and Application of Power System (Douban) Learn with this book, and you can basically master its simulation. BPA and PSASP mainly aim at digital simulation of power flow and motor transient. PSASP_ free high-speed download. Because PSASP is developed by China Electric Power Research Institute, many graphics and data are in line with national standards and easy to learn. Just do a few more examples. Let's talk about what these softwares can help us: 1. When I manually calculated the short-circuit current and power flow distribution of a seven-node power plant system for the first time, it took me three days and more than 20 draft papers, which was a considerable amount of calculation. Later, PSASP is used to calculate the short circuit and power flow of this system, which can be completed in about ten minutes. The key point is that the calculation amount and difficulty of system short-circuit current increase exponentially with the number of nodes. It is impossible to calculate a system with three nodes and dozens of nodes in a few minutes, while software such as PSASP can calculate a system with hundreds of thousands of nodes. 2. Besides, there are too many things that matlab/simulink can do: What can matlab do in the engineering field? Are there any examples of applications in electrical engineering? -Shen Sunhe's answer, if mastered, can be used to do many, many interesting things. Matlab tutorial _ free high-speed download 3. The first three are the key points, because our professional experiments are dangerous and infeasible, and they are all simulated by software. Then the first two software simulations can basically meet our professional experiments and circuit simulations. As for CAD, in fact, the focus is on the future work, especially those who are engaged in electrical design in the future: those who are engaged in drawing by Party B, hehe, not to mention how hard it is: except for the electrical design of buildings, the copyright actually used in the design of power plants and substations belongs to the author. Please contact the author for authorization for commercial reprinting, and please indicate the source for non-commercial reprinting. 4. Finally, I think this BPA is the most useful software in our major, but it is not easy for beginners to get started, but once they learn it, no matter how complicated the network is, it is the best software to use. You only need to write relevant cards and documents to get the results, which has absolute advantages over PSASP in convenience; The most important point is that the user interface lags far behind PSASP. When you use PSASP, you will find that there are many operations without shortcut keys, but BPA is a very friendly software, which can perform many convenient operations (such as modifying, moving components, adding data, etc.). ).
