Power Electronics Power Transmission What professional foundation do graduate students need?

It has to be powered by electronics. There is this book. The retest didn't tell you what to test?? My classmates' re-examination is over, and you have to take a look, and the knowledge you have learned is within the scope of the re-examination.

Combined with my experience, I would like to give some suggestions to the landlord.

If you are a major in power electronics and DAO power drive, it is recommended that you specialize in switching power supplies. In the direction of power electronics, there are many power supplies, such as sine wave inverter power supply induction heating power supply But switching power supply is the most promising, but also the highest salary, it is very difficult to be proficient in switching power supply, if you can really be proficient in switching power supply, the current ** in foreign companies (such as Philips, Delta Electronics, etc.) monthly salary of about 30,000 is still very possible.

Let's talk about the most important courses to learn switching power supplies.

1) Power electronics.

2) Circuit analysis.

3) Automatic control.

4) Transformer principle and design.

It is necessary to learn power electronics and circuit analysis for power supply, and it is necessary to learn automatic control after switching power supply to a certain extent, and be very proficient in the Bode diagram and Rashorn transform in automatic control.

Then you have to be proficient in transformers, transformers look simple, but when you really design them, you will know how deep the water is inside. Let's put it this way, if you learn the transformer well, you will basically learn the switching power supply well. The design of a transformer involves a great deal of knowledge of magnetism.

In short, the switching power supply is very promising, but it is not easy to learn well, after 5 or 6 years of work, if you can study seriously every day, and at the same time have a good predecessor to take you, then maybe you can be proficient in switching power supply, otherwise it may take more time to be proficient in switching power supply, just say so much, I wish the landlord success in his studies.

This is related to the overall research direction of your school, and power electronics and power transmission should be a direction under the electrical engineering major. Specific to each research direction, they are roughly similar, rectifiers, step-down, switching power supplies or inverters, just these links. If you want a high salary, you have to look at your strength.

It depends on the strength of your school, this major is relatively easy to employ.

The employment prospects for these two majors are both positive and mixed. Supply exceeds demand, there are many graduates, the economy is weak, and employment is restricted.

The development of state-owned enterprises is subject to many policy constraints, one time and another. The State Grid and China Southern Power Grid have been better in recent years, and since last year, the income constraints have begun to be strict. State-owned enterprises are intertwined, the relationship is complex, talented are not necessarily useful, most of the professional should be in the line, personal opinions, for people who are content with the status quo, suitable for state-owned enterprises; For those who want to mix in the career, it is suitable for state-owned enterprises; The benefit of a state-owned enterprise is that there is a stable career and no pressure.

With the development of electric power, all kinds of services and power industries and technologies are constantly updated, and the future is broad. Some joint-stock enterprises, joint ventures and enterprises directly under the power grid are vying for turf and fierce competition. Power products are profitable, and there are more companies joining, which is inevitably mixed.

Men are afraid of entering the wrong industry, and women are afraid of marrying the wrong man, so the first thing to do is to choose the right unit, a unit with development potential. Secondly, it is necessary to choose units with scientific internal management and reasonable distribution. There will be no pie in the sky, and high-income income is directly proportional to one's ability and dedication.

There is no low income in the early stage, and there will be no high income in the later stage.

The power industry is high-tech and high-capital, and it will be very difficult for school graduates who do not have original accumulation to start their own businesses. Not the target of choice.

As far as the power grid is concerned, you can go to the south or go to the south, the income gap between the north and the south is still relatively large, and it is not good to say whether you are comfortable; In addition, the annual income is also up and down, and the impact of the specific position on life is also a huge difference, to sum up, into a good unit, and then go to a department that is not so day and night, as long as you work hard, personal development will still have, of course, no background do not expect to be a big leader.

As far as your location is concerned, Power Electronics and Power Transmission recommends you to go to Hefei Industry or China University of Mining and Technology (Xuzhou), and Electrical Machinery and Electrical Appliances recommends you to go to Shanghai University.

The first choice is 211 University, North China Electric Power University, if you think this is difficult, Hohai University, Beijing Jiaotong University, Southwest Jiaotong University, Hebei University of Technology, Hefei University of Technology, China University of Mining and Technology, these 211 are not bad, you are from Zhejiang. Kao Mining University and Hefei University of Technology, Hohai University is closer to you.

China's top universities: China's top 10 universities with the most development potential (Source: Xinhua News Agency).

1. Harbin Engineering University - With the country's huge national investment in the cause of "three seas and one nuclear" implemented year by year, Harbin Engineering, which has about half of the faculty of the predecessor Kazakhstan Military Industry, will surely become famous all over the world, and its strength and popularity will rise sharply.

2. Central South University - as rapid as Huazhong University of Science and Technology, Hunan has a profound literary style, and its economic strength has improved rapidly, so it is not a problem to support Zhongnan.

3. Huazhong University of Science and Technology - its rapid progress makes many brothers jealous. It is located in Wuhan, the thoroughfare of nine provinces, water and land transportation are developed, and the times require those in power to pay attention to the immediate achievements, so Hubei will favor engineering colleges and universities and snub Wuhan University.

4. Ocean University of China - Haida's unique professional setting determines its unique position in people's minds, as evidenced by its wide acclaim in China and Asia.

5. Sun Yat-sen University - gives people the impression of relying on money to feed fat, but its wide popularity, many alumni, and complete disciplines are its brilliant resources. In addition, it is located at the forefront of reform and opening up, and there is no doubt that Guangzhou will take off in the future.

6. Xidian University - after the dignified Xijun Electric, it is a relatively pocket-sized university, and its solid discipline foundation and the popularity of students' employment in the high-tech field make the students of Jiaotong University and Xi'an University of Technology in the same city silent.

7. Beijing University of Aeronautics and Astronautics - China will greatly increase investment in the field of aerospace, only this one, Beihang will have a bright future.

8. Shanghai University of Finance and Economics - Shanghai's development orientation is one of the world's financial centers in the future, therefore, its talent cannot be Fudan and Jiaotong University in the same city.

9. Lanzhou Jiaotong University - The renaming of Lanzhou Railway College has caused discussion among the four Jiaotong universities in the mainland. With the large-scale development of the western region, the state will certainly make great achievements in railway construction, and this has become a geographical advantage of Lanjiao.

10. Jilin University - The new Jilin University inherits the strong majors of biology and computational mathematics from the original Jilin University, and integrates the characteristic disciplines of the other three universities, making it firmly in the top spot of the comprehensive university in Northeast China.

The Department of Electrical Engineering at Zhejiang University has a long and famous history, and it depends on your grades.

Taiyuan University of Technology, majoring in electrical engineering.

Majoring in electrical engineering at Southwest Jiaotong University.

North China Electric Power University Electrical Engineering (Professional Degree) 985 Beijing Institute of Technology Electrical Engineering 985 Jiangsu University Electrical Engineering.

There are really a lot of graduate schools in the direction of electrical engineering, dear, 211 is also a lot, give you a few top rankings, you can screen them.

It's not complete yet, and there's more, so let's take a look.

Power electronics and electric transmission mainly study power conversion and its application in different occasions, such as new energy: solar energy, wind energy, etc., these energy sources need to be converted between AC and DC, taking solar energy as an example, it itself is DC low-voltage electric energy, which needs to be converted into high-voltage AC to be connected to the grid as needed; Power conversion required by various electrical equipment: DC DC conversion is required for inverters, mobile phones, notebooks, electric vehicles, etc. used for motor drive; Power transmission and distribution includes static reactive power compensation, DC transmission and distribution, etc.

Undergraduates mainly study the basic courses of engineering, such as digital, analog, single-chip microcomputer, but also learn power electronics technology, control and other related professional courses, and graduate students should be divided into different research directions according to the above different applications, which depends on the research direction of the supervisor!

Beijing here seems to be a test of power system analysis, professional courses test transient and steady state analysis of two books, the school will have an exam syllabus, if you don't come out, please go to the postgraduate examination forum to find previous years, the content of the exam will not be too different every year.

During graduate school, there will not be much difference between power electronics and power systems, some do software and some do hardware, but there will be people in the power system major who do the same thing as you, it all depends on the teacher, some teachers such as Xiao Xiangning, both power electronics and power system. But from the point of view of employment, power electronics is not as optimistic as the power system. Huadian takes the system as the measurement standard, and the proportion of power electronics entering the system is far less than that of the system and the direction of high voltage.

But a foreign company like ABB and Siemens is actually no worse than a power supply bureau or something.

At present, Huadian's highest score is in power system, followed by high voltage and power electronics, followed by higher and higher scores in electrical engineering (professional master's degree).

If you love power electronics, you might as well go to a school like Huazhong University of Science and Technology.
