The experimental base of the SMES research group is located on the west side of Xihai City, covering a large area.
The main entrance of the base looks like a dilapidated factory, with only two rusty iron doors and a small post booth with armed guards standing guard.
Behind the iron gate is a fairly spacious dirt road.
Only after walking along the dirt road for more than two hundred meters can you see the gate inside the base.
Many people are already waiting there.
Wang Hao already knew the news yesterday, but because the expert team's itinerary was confidential and he only knew that they would come to check today, he didn't know that the expert team was coming half an hour in advance, so he simply waited at the door with the others.
.
Xu Baogong is no longer an outsider.
Whether it was related to scientific research or meetings, Wang Hao and Xu Baogong had met many times. When they met again, it was not a false politeness, but a sincere handshake.
Xu Baogong sighed, "Academician Wang, you can really do anything. Research a superconducting energy storage device. I originally thought it would take a long time, but it turned out to be such a surprise for me."
Wang Hao smiled and said, "There is just some progress. You came at the right time. I was worried about some things."
"What's up?"
"Electricity problem!"
Wang Hao shook his head a little depressed and led a group of people into the experimental base.
They talked as they walked.
The expert team walked around the perimeter of the SMES experimental device. Because the experimental device has been running, there are no protection measures inside, and there is no way to go in and see directly. There is nothing visible from the outside.
The group of people finally walked towards the office building.
Along the way.
Liu Mingkun kept talking about the research progress, "The experimental device we built was turned on a week ago. The initial charging power was less than 5,000 kilowatts. In the past two days, the power department has pulled new lines to increase it to 10,000 kilowatts.
.”
"It's been a week now." He said with a somewhat proud tone. "Although the system fault detection in the background also has high fluctuations, it has never exceeded the critical value."
"For the time being, we are charging with a power of 10,000 kilowatts..."
Wang Hao also followed up, "Our next research plan is to detect whether overload power charging will cause excessive pressure, and the other is to detect high voltage resistance."
"The fastest thing to do is the discharge experiment, but it still takes time."
"If there are no problems along the way, we will definitely have to fully charge the battery so that the device's power capacity reaches its extreme value."
He shook his head dejectedly as he spoke, "But no matter which target it is, it needs enough power supply."
"The current power supply is still too poor. We still hope to have a high power supply of 50,000 kilowatts..."
"Minister Xu, you must solve this problem for us as soon as possible. Normally, the power supply of 50,000 kilowatts is not so high that it cannot be supplied..."
Xu Baogong shook his head and smiled.
He is the person in charge of high-tech in the Ministry of Science and Technology, and he cannot directly manage the power department.
In addition, they definitely support the research and development of SMES technology, but practical problems must be solved realistically.
Along the way just now, he saw the situation and the power department was also solving the power supply problem.
However, if you want to realize the transmission of 50,000 kilowatts of electricity, you can't just turn on the switch. It will definitely take a certain amount of time.
Among them, experts in electricity science understand that a power supply of 50,000 kilowatts can continuously ensure the power consumption of tens of thousands of households, which is equivalent to the power consumption of a large manufacturing factory.
Every large-scale manufacturing factory must first solve the problem of power supply when planning to build a factory.
Then new power facilities need to be built, and the power department must coordinate power use to ensure that large factories continue to use power.
This does not mean that it can be solved. It will take more than a month at the earliest, and sometimes it will even take several months or a year.
When the topic entered this stage, others also realized that the SMES power storage experimental device manufactured by Wang Hao's research group was indeed charging at high power all the time.
Many people looked at Pan Dong frequently. Pan Dong kept saying along the way that the new experimental device must be low-power charging.
Pan Dong's expression was full of seriousness. He didn't say anything, but he was obviously much more serious than the others. Especially after entering the monitoring room, he kept checking various data, asking about each screen, and the fluctuations in the computer display.
He still doesn’t believe in the so-called ‘continuous high-power charging’.
"This is absolutely impossible. There must be something wrong somewhere."
"Be sure to take a good look."
"Research, what is the problem? This is impossible, there must be something wrong..."
The progress of Wang Hao's research team has exceeded his knowledge.
After checking for a long time, Pan Dong couldn't find the problem, so he simply asked, "How do you solve the problem of quench protection?"
He was asking about Liu Mingkun.
Liu Mingkun was stunned for a moment, "Professor Pan, are you talking about the detection problem of the energy storage coil? We have background fault monitoring for this."
He took Pan Dong to a computer. The screen showed a basically parallel line, with occasional bulges that were not large. "This is the fault monitoring system. If there is a problem, the display will fluctuate greatly."
Pan Dong shook his head and said, "I saw it just now and know that you have this system. Our research team also has this system!"
He spoke louder, causing people in the distance to look over.
Pan Dong didn't care at all. He continued, "I mean, how did you solve the quench problem when you encountered it?"
"This..." Liu Mingkun suddenly became speechless.
Pan Dong's eyes lit up, could this be the problem?
At this time, Liu Mingkun said, "The problem is, have we not encountered the problem you mentioned?"
"..."
Pan Dong was stunned and didn't know how to continue asking.
If someone doesn’t encounter a question, how can he answer it?
But……
It’s impossible not to run into problems!
Liang Jingye walked to the front and said professionally, "The quench problem generally exists."
"Affected by many factors, energy storage coils will always have problems such as instantaneous overcurrent, thermal interference, increased resistance, overheating, instantaneous high voltage, etc., which will cause safety problems in energy storage coils."
"The inductance of the superconducting energy storage coil is relatively large, and the operating current of the energy storage coil fluctuates for a long time, making detection very difficult..."
Liang Jingye said a lot of things very professionally, and she also said that Liu Mingkun didn't know how to answer.
These are so professional!
Although he is the deputy director of the research team, he is involved in many internal design details and does not know the specific situation. The detection of energy storage coils and the computer background operating mechanism are not his responsibility at all.
Seeing Liu Mingkun being questioned, Pan Dong suddenly smiled and looked at Liang Jingye with relief.
Wang Hao came over and said, "Team Leader Liang, all the issues you mentioned should be related to design, right?"
He continued, "The design we made is very complete and balances the monitoring of each part. We have placed detection instruments at the reference position of each coil."
"In addition, we also have insurance-type internal and external three-layer detection, including voltage, temperature and power overload, with detailed detection systems."
"All data will be uploaded to the background and undergo a series of automatic analyses, which will eventually be reflected in fault fluctuations."
After hearing this, Liang Jingye shook her head and said, "Then it's impossible to completely avoid the quench problem."
She continued, "My team specializes in troubleshooting energy storage coils, and later discovered that the high-temperature superconducting energy storage coil technology provided by the electricians itself had problems."
"This technology can indeed greatly improve the efficiency of electrical energy storage, but it will weaken the pressure-bearing capacity of the coil."
After hearing this, the people around looked at Liang Jingye differently.
There were some very professional issues that they couldn't understand, but when Liang Jingye talked about the superconducting coil technology provided by electricians, they all knew about it and found no problems at all.
The research on SMES technology directly used the results of the Institute of Electrical Engineering of the Academy of Sciences. As a result, Liang Jingye discovered problems with the results.
This is very unusual.
Wang Hao also looked at Liang Jingye with admiration and said with a smile, "It's really surprising that you can discover this problem."
"However, we did not directly use the technology provided by electricians. In the underlying basic design, we improved the coil winding method from three degrees to two degrees, and also increased the cross section of the coil so that it can carry higher current.
…”
This time it was Liang Jingye's turn to be surprised.
She has also thought about improving the superconducting coil technology provided by electricians, but how can the results of the Institute of Electrical Engineering of the Academy of Sciences be easily improved?
Now that Wang Hao talked about improvement methods, we immediately started discussing with him.
The more they talked, the more professional they became. At first, there were several people listening, but later they all walked away when they realized they didn't understand.
Later, even Pan Dong walked away.
Everyone else looked at the data from the testing room, and some people from the research team helped introduce what each data represented.
After all the introductions, everything will be clear to you.
At this time, everyone already believed that the SMES energy storage experimental device was indeed continuously charging with a power of 10,000 kilowatts.
In fact, most people believed it at first, because it was impossible for Wang Hao to fake it. For Pan Dong, SMES technology was a scientific research pursuit, but for Wang Hao, it was just a piece of research.
Even if the research on SMES technology cannot be completed, it will not have any impact on Wang Hao personally.
At this time, Pan Dong was still studying it carefully. He really hoped to find out the problem, but now even he believed it.
That's the problem.
Everything in front of him was beyond his understanding.
At the same time, Pan Dong also felt that it was unacceptable. Wang Hao's research team only spent three months to make the SMES experimental device capable of stable high-power charging.
The continuous high-power charging of the SMES experimental device is equivalent to solving most of the problems.
Even if a malfunction occurs later, the problem will definitely be found and solved.
It's like building a computer. It will encounter many problems when it is turned on. After starting, the software may have many problems.
When there is no external interference, such as virus invasion or external force damage to the equipment, the computer can be used for a long time, which means that there is no problem with the computer itself.
Subsequent failures suddenly occurred, and in most cases it was hardware damage.
The same goes for the SMES experimental device. It can be charged at high power for a long time. After a long period of time, if problems occur again, it is likely that the internal device is damaged.
This is a quality problem of the internal device, which may not be directly related to the design and technology of the research team.
Therefore, Wang Hao's research has entered an advanced stage.
Here comes the problem...
It only took Wang Hao's research team three months to reach the advanced stage. Then wouldn't their efforts in the past two years have been in vain, and they can be disbanded immediately after returning.
Thinking of this, Pan Dong felt extremely depressed.
…
Everyone in the expert team can understand Pan Dong.
Although they thought Pan Dong was funny and said "there must be something wrong" along the way, they found that there was no problem at all.
However, Pan Dong is also very pitiful.
The competition in many scientific researches is very cruel. When doing the same research, if one team does it first, another team will put in more efforts, which means nothing.
This is the situation Pan Dong is encountering now.
They worked hard for two years, but were surpassed by Wang Hao's research team in three months, and were still far behind.
After they go back, it is basically impossible for their research to continue. They will either be merged into Wang Hao's research group, or they will have to face disbandment.
So Pan Dong had a sullen face all the way, with no smile at all.
Liang Jingye didn't seem to feel any pressure. She kept talking to Wang Hao about professional issues, and at the same time she felt very amazed in her heart.
She found that Wang Hao knew every part of the SMES power storage experimental device very well, as if he was involved in the details of the design of every part.
Wang Hao not only knows the details of the design, but can also explain the principles of the design.
This is an amazing thing!
The SMES power storage experimental device is very complex.
Liang Jingye thinks that she is very involved in research, and she only understands the energy storage coil part in detail.
In Pan Dong's research team, Pan Dong is only responsible for the general design, experimental work, some device details, and small technical aspects. He has no involvement at all. If problems arise, he can only seek the opinions of others.
This is normal.
This is the case for most research team leaders of large projects.
For example, the chief designers of some large projects are only responsible for grasping the general direction of research and development. Some technical problems in research are also handled by specialized technical groups below.
Liang Jingye looked at Wang Hao with eyes full of admiration and admiration.
When she thought that SMES technology was just a piece of Wang Hao's research, which could even be said to be "not worth mentioning" compared to the theoretical research he had done, she felt even more impressed.
Others feel the same way.
Needless to say, Wang Hao's genius is natural. As for the project itself, they were surprised by the speed of Wang Hao's research team.
Just three months!
Many research projects have just started in three months, but Wang Hao's research team is already at an advanced stage of progress.
At noon, the research team invited us to have a meal together.
Xu Baogong and Wang Hao sat together and talked about ensuring high-power power supply as soon as possible, "This aspect can definitely be guaranteed."
"I will talk to the power department specifically and ask them to try to solve it within a month!"
Wang Hao was relieved now.
After meal.
A group of people walked outside. Wang Hao continued to walk with Liang Jingye and asked again, "Team Leader Liang, it's the same question as last time. Are you interested in coming to work with us?"
He said it very straightforwardly.
The people nearby immediately looked at Liang Jingye, while Liang Jingye looked at Pan Dong hesitantly.
Pan Dong's face turned dark when he heard this.
He said in a serious tone, "Academician Wang, Xiao Liang is an indispensable talent in our group!"
Wang Hao smiled apologetically and nodded, seeming to accept Pan Dong's statement.
Liang Jingye was embarrassed and didn't know what to say.
Others looked at Pan Dong strangely, because they all knew that the rapid progress of Wang Hao's research team would definitely affect Pan Dong's team, and whether his research team could continue to exist was a question.
Pan Dong also knows what other people think.
Even if his research group is disbanded directly, he does not want to see Liang Jingye go to Wang Hao's research group.
He found another reason, "Indeed, there is a big gap between our groups, but Academician Wang's research is almost completed, and there is no need for anyone else."
This reason is quite reasonable.
The SMES power storage experimental device is already capable of stable high-power charging, and subsequent failures can be easily solved. The research can be said to have entered an advanced stage.
What’s the point of Liang Jingye participating in the research again?
Wang Hao frowned and said, "Professor Pan, you are wrong. How can we say that our research is almost completed?"
"Isn't it?"
Pan Dong immediately said, "Your experimental devices are all capable of high-power charging. At this stage, the follow-up work will be smooth and routine testing."
Wang Hao continued to shake his head and said, "Professor Pan, I think you probably didn't notice the name of our project?"
"What's the meaning?"
Others looked over without knowing why.
Wang Haodao, "What we are doing is research on SMES batteries. The purpose is to provide energy power support for future aviation technology, not to manufacture SMES power storage devices."
"Not only is our research not over, it has only just begun!"
