Urgent! Urgent! Urgent! Are there any brothers and sisters of Huadian? Tomorrow, Huaneng International will interview, ask for guidance, and get high marks online.

I am a graduate of 2009, and graduated from an ordinary undergraduate course in Jiangsu.

I once saw the recruitment information of Huaneng Yuhuan 4* 1000MW on Polaris Power Cai Ying. I have a look, damn it, there are four 1000MW generators, which is also the largest thermal power plant in China (of course, it is not as good as the 26*700 hydropower generation of the Three Gorges, but it is not a power plant, but a power station, hehe). I looked at it carefully.

That time (that is, Huaneng interviewed in Hangzhou and Beijing at the beginning of March this year), I was in Nanjing, one day in advance, at the Party School of Zhejiang Provincial Committee. It took me 5.5 hours to get there by train. Fortunately, on the same train, several of them were kindred spirits with me, and then they left together.

The next day, people who had been informed about 160 came about 5 1, which was not bad because there was another interview point in Beijing. The written test in the morning, the interview in the afternoon and the written test questions are very basic, but you can't do some basic ones, because some of them are engineering problems, and the written test questions will be attached. The interview experience is very painful, because the electrical meeting will be 35 days later, and the first one will be 20. There is also a platform for communication. Huazhong University of Science and Technology, Shanghai Jiaotong University, many famous universities have come, many from Zhejiang and some from Nanjing. What's even more frightening is that they came to Shihezi University by train 200 kilometers west of Urumqi for 66 hours. Hehe, I have never heard of it. It's strange to hear that a university supports a county-level city. I will never go there in my life.

Later, the organizer found that 20 minutes was a long time, and it was almost impossible to finish it in an afternoon evening. Later, everyone had less and less time. It's been five minutes since we arrived at electrical engineering (oh, I forgot to say, the written interview is divided into majors, thermal engineering, thermal control and electrical engineering). God, what can I meet in five minutes? Generally, professional questions are rarely asked, such as "self-introduction, academic performance and some topics." If the interview is ok, he will keep you waiting for news. If not, it is very direct, so that you can find a job quickly. However, they also admit that the chances are not great. Each major only accepts 1 1 person, and there is no news after half a month.

Attachment: Huaneng Yuhuan 2009. 3 written test questions (about 90%)

Fill in the blanks (1* 10) (I can't remember a single space)

1 The mass of the diode on the multimeter side should be within the range of () of the multimeter, and ABC on the transformer stands for () color respectively.

2 The work done after the electric field force makes the conductor move a certain distance is called ()

In the power generation system, the part that converts non-mechanical energy is called () power, and the part that converts electric energy is called () power.

4 The basic requirements of relay protection are: (); Rapidity; (); Reliability.

5 adjust the synchronous generator () can mediate the reactive power distribution of generator voltage system.

6 synchronous generators connected to the grid are required to run stably, and each synchronous generator should run ().

True or false (that's all I remember. Everything else is easy to handle. I only know that the last eight questions are complete and correct. The sentence is long and obviously correct, just like 7)

1 The total length of current quick-break protection is related to the operation mode ().

2 The greater the generator capacity, the greater the frequency; The smaller the capacity, the smaller the frequency ()

3 to expand the ammeter capacity should be series () resistance.

4 in household appliances, the power switch should be installed on the live wire side ()

5 inverse time current protection, the greater the short-circuit current, the longer the action time ()

6 lightning arrester is in lightning by the needle to avoid voltage ().

The power system consists of generators, transformers, transmission lines, circuit breakers and other primary equipment. ()

Multiple choice questions (2* 10) (I only write two options, which are not difficult) (it is easy to delete one and forget the other)

1 In a pure inductance circuit, the phase of voltage and current ().

A is 90 degrees in front and B is 90 degrees in the back.

2 the following according to the conductivity from big to small are ()

A silver copper aluminum iron b iron aluminum copper silver

3 in the EHV no-load circuit, the terminal voltage is higher than the initial voltage ()

A is low level and b is high level.

4 Three-pole asynchronous motor with speed of ().

A is greater than 1000 rpm, and b is less than 1000 rpm.

5 Current fast sectional protection ()

A can't protect the whole line, and whether B can protect the whole line is related to the operation mode.

6 a transformer, the voltage is 220/380, and its connection mode is ().

Triangle/star b star/triangle

7 when three-phase alternating current is passed through the stator winding of synchronous generator, () will be produced.

A rotating magnetic field b pulsating magnetic field

8 power factor is ()

A P/S B Q/S

Four questions and answers (5*6) (complete)

How much do you know about the system of thermal power plant? Try to write five systems.

What is the method of changing AC into DC? What is the way to change DC to AC?

Five comprehensive questions (2* 10) (complete)

1 auxiliary transformer voltage 6kv, Se=2000kVA, transformation ratio 6.3kv/0.4kv to find the primary and secondary side currents of the transformer.

We all know that some lights at home are controlled by two switches in different positions. Try to write the circuit schematic diagram of this control.
