Urgent! urgent! urgent! Are there any seniors from Huadian? Interview with Huaneng International tomorrow, looking for guidance, high scores online, etc.

I am a 2009 graduate from a general undergraduate university in Jiangsu.

I once saw the recruitment information of Huaneng Yuhuan 4*1000MW on the Polaris Power Talent Network. I took a look and thought, damn, having four 1000MW generating units can be regarded as the largest in the country. Thermal power plant (of course it is incomparable to the 26*700 hydroelectric power plant of the Three Gorges, but it is not a power plant, it is a power station, haha). I took a closer look and found that I need to send my recruitment materials by mail. It is quite formal. Yes!

That time (in early March this year, Huaneng had two interview locations in Hangzhou and Beijing), I was in Nanjing, one day in advance, at the Zhejiang Provincial Party School. It took a 5.5-hour train ride to get there. Fortunately, there were a few people on the same train who were on the same path as me, and we went together.

On the second day, about 51 people came out of the originally announced 160 people, which was pretty good, because there is also an interview point in Beijing. There was a written test in the morning and an interview in the afternoon. The written test questions were very basic, but there were some basic ones. You still don’t know how to do it, because some of them are engineering questions, and the written test questions are attached at the back. The interview experience is very painful because you have to wait. The electrical ones are all after 35, and the first one takes more than 20 minutes. If you wait to death, there will be In order to provide a platform for exchanges, Huazhong Science and Technology, Shanghai Jiaotong University, and many famous universities have come, as well as many from Zhejiang and a few from Nanjing. There are even scarier ones, 200 kilometers west of Urumqi and a 66-hour train ride from Shihezi. University, haha, I have never heard of it. I only heard that person say that it is strange for a university to support the people of a county-level city. I will never go anywhere in my life.

Later, the organizer found that 20 minutes was a long time, and it was almost impossible to complete it in one afternoon and evening. Later, the time per person became less and less, and in the electrical category (oh, I forgot to mention, the written test and interview points (Professional, Thermal Dynamics, Thermal Control, Electrical) It’s already 5 minutes per person. Oh my God, what can I interview in 5 minutes? Generally, I rarely ask some professional questions. I asked questions such as "self-introduction, academic performance and some topics." It has nothing to do with the major. If the interview goes well, he will ask you to wait for news. If not, he will be very direct and tell you to find a job quickly. However, they also admit that the chances are not very good, and each major will only charge 11. Personally, there was no news after half a month.

Attachment: Huaneng Yuhuan 2009. 3 test questions (probably memorized 90%)

One fill-in-the-blank question (1*10) ( There is one more thing that I can’t remember)

1 Use the () position of the multimeter to check the quality of the diode on the side of the multimeter. The ABCs on the transformer represent the () colors respectively.

2 The electric field force. The work done by moving a conductor a certain distance is called ()

3 In a power generation system, the part that converts non-mechanical energy is called () power, and the part that converts electrical energy is called () power

4 The basic requirements of relay protection are: (); rapidity; (); reliability.

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

6 requires that all synchronous generators connected to the power grid can operate stably, and each synchronous generator should () operate.

Two true-false questions (I only remember these, the others are easy, I just I know that the last 8 questions are all complete and the correct sentences are very long, and they are all obviously correct, just like 7)

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

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

3 A resistor should be connected in series to expand the ammeter capacity ()

4 In household appliances, the power switch Should be installed on the live wire side ()

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

6 The arrester relies on the needle tip to avoid overvoltage during lightning strikes ()

7 The power system is composed of primary equipment such as generators, transformers, transmission lines, and circuit breakers.

()

Three-choice questions (2*10) (I only wrote two options, they are not difficult) (I deleted one of the questions, and I can’t remember the other one, they are all easy)

1 In a pure inductance circuit, the voltage and current phases ()

A leads 90 degrees B lags 90 degrees

2 The following are listed in order of conductivity from large to small: ()

A silver copper aluminum iron B iron aluminum copper silver

3 In an ultra-high voltage no-load circuit, the terminal voltage is higher than the starting voltage ()

A low B high

4 A 3-pole asynchronous motor with a speed of ()

A greater than 1000r/min B less than 1000r/min

5 Current speed segment protection ()

A cannot protect the entire length of the line B. Whether it can protect the entire length is related to the operation mode

6 A transformer with a voltage of 220/380 and its wiring method is ()

A delta/star B star/delta

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

A rotating magnetic field B pulsating magnetic field

8 The power factor is ()

A P/S B Q/S

Four questions (5*6) (complete )

1 What are the levels of power transmission and distribution voltage in my country? Try to write down at least 5 types?

2 What are the commonly used high-voltage busbar wiring methods in thermal power plants? Try to write down at least 5 of them?

3 What should you do if someone gets electrocuted?

4 What do you know about the systems in thermal power plants? Can you try to write down 5 systems?

5 What is the method of converting AC into DC called? What is the method of converting DC into AC called?

Five comprehensive questions (2*10) (complete)

1 The voltage of the factory transformer is 6kv, Se=2000kVA, the transformation ratio is 6.3kv/0.4kv, find the transformer 1 and 2 secondary current.

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