"The specific technical issues of the firewall will be discussed separately after the meeting. Hua Changqing still understands things in the end, and it is not good for the two of them to communicate in public and high-end after all, he hurriedly turned to Mu Hengzhi and said, "Minister Mu, I think this road is feasible, we can go and have some contacts." ”

"Hmm. Mu Hengzhi then nodded, "Indeed, at the International Power Grid Conference, the people of the American power company also focused on the future network security issues, and deliberately introduced the concept of firewalls. ”

Mu Zhiheng's voice fell, and with the sound of the meeting recorder's pen writing, it meant that the firewall had become a proposal in the real sense, an urgent thing to do.

It was also difficult for others to interject, only to look at the inconspicuous undergraduate student in the back row, whether it was fooling or real ability, in short, this kid could bluff Hua Changqing, in a sense, he was already the most powerful person in this room.

As for Lao Zou, he is a person who has lived for more than 60 years, and he will not be unable to understand the minister's attitude, and it is no longer good to say anything more at this time, so he can only gasp and sulk in place. But it's hard for him to blame Zhang Yifu for provoking the trouble, this kid still has a very good attitude, and he is right-hearted......

"Leaders, I still ......have a little idea," Zhang Yifu looked at Mu Zhiheng and Hua Changqing instructively.

"It's a big deal. Mu Zhiheng will definitely not underestimate the technician of this power plant at this moment, and listen attentively.

"The second improvement plan is for this accident, the monitoring crash can not be directly led to tripping, the direct cause is due to the monitoring crash, the grid-connected command signal disappears, which is equivalent to giving all units a shutdown order. I have probably studied the monitoring system of Jiutan, and the grid-connected signal of the current unit is completely controlled by the monitoring system, that is to say, once there is a problem with the monitoring, the whole plant will have problems. As far as the matter is concerned, I think that under the existing technical conditions, we can add a way to convey the grid-connected signal, that is, the introduction of the switching state quantity, not through the guò monitoring system, and convey it to the unit alone, so that even if the monitoring system is paralyzed, the unit will still not lose the grid-connected signal, and can continue to operate normally according to the power value before the monitoring failure, and at the same time send out an alarm signal, so that the staff can deal with it in time. ”

The concept of firewall, may be a bit high and low, but the amount of switching state is undoubtedly more down-to-earth, simply put, this is the "o" or "1" two numbers, the unit receives "1", it is equivalent to receiving the grid-connected signal, continuous work.

Some engineers who have studied automation immediately began to think about the feasibility of such an option.

The switching state quantity and the monitoring system go hand in hand, and the grid-connected power control unit is simply the norm after 2o years, not that these engineers are stupid and can't think of it, but the current automation knowledge is too classical.

There is a saying that one point makes sense, everyone is engaged in technology, and their academic qualifications are bachelor's, master's and doctor's degrees, for them, the enlightenment brought by the "introduction of state quantity" is actually not more complicated than saying to Niu Dameng "add a support oil pan", and the engineers immediately began to communicate with the left and right, and said what they think is feasible.

This switch state quantity, can be operated manually, very simple, only need to construct a number of channels can be completed, even if the monitoring crash, can also ensure the operation of the unit, the real double insurance, but the unit power can not track the scheduling instructions in real time, but it is also temporary, as soon as the alarm comes out, the watchman can immediately resume manual operation.

Such a practical improvement plan inadvertently opened the minds of the technicians, and the atmosphere of the whole venue was also stimulated. At this time, Zhang Yifu can sit down silently with satisfaction, these seniors in front of him are full of wisdom and only need a gentle push.

At this time, Mu Hengzhi on the main seat finally showed a relieved expression, this is a technical seminar, regardless of factions and interests, to discuss technical problems and propose solutions.

He casually asked left and right: "This concept of switching state quantity seems to be more down-to-earth." ”

"I have limited understanding of the problem of automation, so ask Huagong. The leader of the safety supervision department on the left smiled, "Is this concept popular in the United States?"

Hua Changqing immediately shook his head: "No, I have never heard of the use of switching state quantities in the United States to achieve double insurance for grid-connected signals...... It's really a ...... It's a simple and innovative idea...... It's so easy and doable, why didn't anyone come up with it......? Is it really an undergraduate? Working in a power plant?"

Mu Hengzhi smiled and took out the meeting materials, pointed out Zhang Yifu's name on the list, and handed it to Hua Changqing: "That's right, I just graduated this year, Zhang Yifu." ”

Hua Changqing looked at the name, and his eyes suddenly lit up.

"Wait!" Hua Changqing exclaimed, "Zhang Yifu...... ZHANG Yifu ...... Isn't that the ...... That's on the answer sheet!!"

Director Liu inspected one of the graduates' answers and asked them to look forward to China's power industry in 20 years. Hua Changqing's excitement was already overflowing, "I didn't expect to meet him here, I didn't expect it to be so fast!"

Mu Hengzhi and the director of safety supervision next to him couldn't help but look at each other.

The young man who made Hua Changqing so interested...... It must not be simple.

first came Duan Youwei's recommendation, and then Hua Changqing's appreciation.

In addition to that, he talked about the real thing in the conference room, opened the minds of the experts, and drove the pace of technical discussions.

Mu Hengzhi squinted at Zhang Yifu, who had already sat down silently, hiding his merits and fame, and looked at the small technician of this big power plant, it was difficult not to have a feeling of appreciation.

is not as crazy as Hua Changqing, understands human feelings, and is willing to commit to the power plant, such a talent, such an age, he has really never seen it in his life.

Since the founding of the People's Republic of China, in order to cultivate talents, he has done everything he can, going to the Soviet Union to study, to the United States, and to Japan...... Finally, today, at this very moment, the real fruit is beginning to bear fruit.

In Mu Hengzhi's eyes, the appearance of Zhang Yifu is not just the excellence of this individual and the efforts of the individual, but the condensation and sublimation of several generations of people.

He couldn't help but look at the lost old Zou again.

You also have credit.

It's just that the future belongs to him.

Mu Hengzhi's reverie has been hotly discussed.

"Now we have a ready-made switching state measurement control device, in fact, this method is used in many power plants, but it is useless because Jiutan is engaged in monitoring automation. ”

"Yes, the transmitters are also ready-made, and only two sets of methods need to be controlled together. ”

"As long as one set of signals meets the conditions, it is connected to the grid. ”

"With such a two-pronged approach, even if the Americans' software is completely paralyzed, they are not afraid of tripping. ”

Everyone's words and words are like an initiation, and as soon as the thinking unfolds, this question is simply too simple, simpler than supporting the oil pan.

Before their negligence is indeed for a reason, the Chinese do things, love to go to extremes, too much, said to be engaged in automation pilot, full software control, so they handed over a qiē to the software, in the most automated way to do the Jiutan power plant, in fact, several of the details only need to be slightly adjusted, can reduce the loss caused by the paralysis of the automation system.

Soon, the topic turned to the appreciation of Zhang Yifu, a little technician.

"Old Duan, your factory Crouching Tiger, Hidden Dragon. ”

"We are all rigid in our thinking, but I didn't expect the comrades at the power plant to think so clearly. ”

"Yes, the current graduates are really amazing, and the automation knowledge has mastered this kind of process. ”

"It has to be the specialty of our Northern Electric Power Institute. ”

"That is, when it comes to the power system, it is really no worse than Tsinghua. ”

After all, 5o% of the people from the Department of Electrical Engineering of Tsinghua University have gone abroad, 15% have gone to sea, 15% have engaged in academics, and the remaining little bit has remained in the power system.

Several major electric power colleges in the country are the mainstay of delivering talents for the electric power industry, and a considerable number of people are alumni of Zhang Yifu.

As soon as the topic changed, it became an exchange meeting of the Northern Electric Power Institute, and everyone talked about the graduates of the 9O class and the things of the previous years.

Mu Hengzhi felt very helpless in an instant, this is the atmosphere is too warm, and the meeting is like this, especially for a meeting of this scale, it is not too simple to run off the topic.

However, he did not stop it, the agenda of the meeting was almost complete, and he was satisfied that he had come up with two excellent solutions. Further, you can explore the application of firewalls to strategically improve the security strength, and retreat, you can introduce only a small switch, which actually eliminates potential hidden dangers.

It's already on this, everyone is willing to talk, let's talk.

In the final analysis, people who engage in technology are still very different from those who engage in power, they are more emotional, more stubborn, especially in the face of technical problems, seeking truth and truth, and often ignoring the problems of interests. Fortunately, this time, due to Zhang Yifu's prominent expression, just like the "oil pan" incident, the problems of interests and corrections have been perfunctory, and the solutions can be listed.

It's rare, and everyone is happy, the so-called conservatives, with Lao Zou's dumb fire, the introduction of state volume, there is nothing to say, even the people who are ready to bombard the muzzle of the cannon at Hua Changqing have also put down their sour mentality and discussed it freely.

Lao Duan silently turned his head and bowed deeply to Zhang Yifu, full of joy, this is the result he wants to see.

Zhang Yifu also nodded in return, thanking the leaders for the opportunity.

He also knew that he could not directly solve the problem with his own conceptual knowledge, whether it was the introduction of firewalls or the introduction of switching state quantities, it would take a lot of complex work, and it would have to be done by the engineers in front of him. Therefore, in the following exchanges, he did not dare to be ambitious, in the face of the problems thrown by others, details, he understands is to understand, not to understand is to ask, is to ask for advice, this humble energy is also quite useful, so that everyone feels that this technician is not so powerful that it is beyond reach, there is also a technical weakness, and he is also a person like himself.
