Katayama still looks dedicated. He politely introduced which computers control fuel delivery, which ones observe the grid parameters, and which ones are circuit breakers that operate transformers and lines and other equipment.√∟

A modern automation power plant is fully displayed in this small control room. For Katayama and even Joe Oda, they are really full of pride at this time. They also have this proud capital, but they can't even say they are arrogant, and they are still polite.

As for Ou Wei's level, he can no longer raise any quality questions, or he has never talked about anything of good quality at all. It took him a long time to think about it before he could hold it back to a problem.

"Is your management here three shifts?"

Even though Oda Chee, who is half an amateur, was a little ashamed, he still conveyed this question and the answer was quickly passed back: "We have a total of 257 employees here, and the operation mode of four shifts and three values ​​is used."

Well, at least Ou Wei asked one thing when he didn't know it, that is, this world-class power plant has a manpower demand of only 257 people.

In addition, the so-called four-shift three-value, also known as four-shift three-operation, is a time management method that the power plant has to choose from, that is, to work 8 hours shifts and then rest for 24 hours, so that it can be repeated, and occasionally take a day off. A week is calculated, it is slightly less than the standard eight-hour day, which seems to be a good loss, but it will definitely become extremely difficult for you to date your girlfriend and have a room with your wife.

Power plants are risky, so be cautious when entering the industry...

In addition, the staff working at the nuclear power plant will undoubtedly suffer a heavier baptism at the same time. Zhang Yifu suddenly knew why the birth rate in Japan is so low, why marriage, love, and wife are so popular.

Wait, the main purpose of this trip is not about the human and wife. Zhang Yifu quickly turned his mind back, and after a brief observation of the automation interface, he asked: "Is the automation system here only the interaction between dcs and private s?"

After hearing the question, Oda Kei was stunned for a moment, but he still forced his translation. Katayama, wearing the gray work uniform of an ordinary worker, fell into a certain confusion.

Not only them, but most of the people on this trip were also confused.

Previously, Zhang Yifu studied the automation system at the National Conference and National Competition, as well as in the courses in his previous life. If he had to say that the power plant operation was not his major, automation was the main business. After all, when he was on duty in his previous life, he was facing this thing all day long.

The three twilight things like dcs, private s and mysterious s jumped onto the table again, skipping those damn terms. In fact, the concept of these three brothers is very simple.

dcs is the information collection, and the bottom layer of the slave unit collects data from the boiler and presents it.

Private S is the middle-level factory control system. The duty personnel here are facing private S. They can observe data and perform necessary control and operations here.

Mis prefers office management, financial procedures, and on-duty arrangements.

Therefore, it is not that difficult to achieve the interaction between dcs and private s at this stage, and Jiutan has basically been implemented, but that is a system built by Americans. It does not meet the needs of Chinese people, so it is a bit poor to use.

With DCS and Private S. It can be said that this power plant has basically completed automation in monitoring. I can see how many degrees in the boiler, and I can easily press Enter and open a gate.

In the environment where automation technology is beginning to become popular, whether to have a perfect MIS has gradually become an important indicator for measuring the automation standards of a power plant and whether it is fully automated and modernized management. If Kashima Power Plant also has MIS and is fully utilized, it can only be said that the gap is a bit big.

After Katayama communicated with Odachi Kiri, Odachi asked: "Kayama hopes you can explain the specific meaning of the abbreviations such as private s and dcs."

"Oh, forget it. This still needs to be communicated with the engineers of the TEC headquarters." Zhang Yifu waved his hand. It seemed that there was no more. I was a little relieved. "Then let me change the question. This operation interface is pure Japanese. Is it translated or self-developed?"

After a little communication, Oda Choi immediately replied: "This automation system is purely developed by TD. TD. has a power software company affiliated with it and has automation technology that is no less than that of Europe and the United States."

After saying that, he did not forget to add: "TongDian's software is used throughout Japan. If you need procurement, we can help communicate. TongDian's software has been running safely and efficiently for a long time."

"I understand." Zhang Yifu really didn't know how to answer him. Japan's hardware is indeed strong, but no matter what, the software is just that...

However, through this conversation, Zhang Yifu became very interested in TD.

In principle, Dongdeng is a private joint-stock company. Now it seems that its business scope is not only about power generation, power equipment manufacturing, power engineering construction and software industry. Zhang Yifu himself is very interested in studying the operation of this enterprise and the rise and fall of this world-class electric giant.

The subsequent visit to the steam engine factory, which should be the highlight, was not good, because everyone has seen Japanese steam turbines. The Japanese steam turbines in Japan are basically the same as those in China. The only difference this time is probably the word "supercritical". Units 5 and 6 of Kashima Power Plant are both supercritical units, and the incoming parameters are 24.12mpa. Zhang Yifu has made up for the supercritical class, and has a qualitative leap in thermal efficiency, which is also a shortcut to fundamentally reduce coal consumption. No matter how much effort is made in other places, it is better to introduce a supercritical unit directly.

Speaking of this type of unit, Joe Oda immediately entered his sales rhythm, talking about the top Japanese motor technology and the advanced supercritical technology. This is indeed understandable. China has just planned to study this thing, but Japan has been using it on a large scale for many years. Their supercritical unit can indeed stand the test.

The Chinese League members heard him talk endlessly, and nodded frequently if they understood or not.

Lao Chang couldn't hold it in anymore, and seized an opportunity and asked: "You said that the stator of this steam turbine generator uses internal cooling and the rotor uses internal cooling. Can you explain why these two internal cooling is adopted? Are there any conditions for dual water cooling?"

As soon as Lao Chang said that Oda Kei became silly. These were promoted according to internal materials. As for water and hydrogen internal cooling, he didn't know what kind of bird thing is. In desperation, he had to ask for advice from Katayama.

After Katayama thought for a while, he answered Japanese and Odaki quickly translated it: "Kayama means that this is more efficient."

Chang Siping shook his head and said, "Water-cooling and hydrogen-cooling are always different from the efficiency. I can accept that double-water-cooling or double-hydrogen-cooling is high, but this kind of thing is called high efficiency, which is really hard to understand."

Oda Kei immediately became embarrassed and discussed with Katayama again.

This problem is indeed a bit difficult for the two of them. After all, it involves deeper professional knowledge. Except for Duan Youwei, the others present are also confused.

But it is absolutely meaningful for Chang Siping to ask this question. This time, for idle people, it was based on the design and management arrangement of Japanese power plants. However, for a motor dynamics expert like Chang Siping, the only task is to understand this supercritical steam turbine, to figure out whether it is so awesome, why is it so awesome, to ensure that the ones we bought can be so awesome, rather than just getting a fool who eliminates it. This is Lao Chang's responsibility and everyone's responsibility, but only Lao Chang can bear it at this moment, because compared to the beach, he pays more attention to this thing.

The stator and rotor sound mysterious, but in fact it is correct to understand it completely literally. The stator is the fixed part of the motor, and the rotor is the rotating part. Faraday told us in the textbook again and again that the principle of electromagnetic induction is actually to cut magnetic lines to generate electrical energy. The huge blades of the turbine constantly rotate and drive the rotor to create a rotating magnetic field. The stator cuts this magnetic field to generate electrical energy. The loss in the process of converting mechanical energy into electrical energy produces heat. We must cool them in some way, otherwise the metal cannot last long at high temperatures.

Air, hydrogen and water have become the only choice.

Among them, the cooling efficiency of hydrogen is slightly better than that of normal air, so for ultra-high-end generators, it is actually just a matter of entanglement between hydrogen and water cooling.

Among them, according to the basic thermodynamics of Shalangyan, the heat capacity of water is extremely high, and the hydrogen efficiency should be slightly lower. After all, it is a gas and the physical properties are here. The water is cool when it comes in and hot when it comes out. After a while, it should be cooler. However, it should be cooler when it is placed in the generator and on the stator rotor. There are more statements about hydrogen cooling and water cooling.

There are experts in the areas where there are some exquisite things. Furthermore, why is Mitsubishi’s 1 million kilowatt supercritical unit water-cooled, and why is it not used for stator water-cooling, and whether it has the ability to use dual water-cooling, it is necessary to understand clearly.
