"We will discuss the specific technical issues of the firewall separately after meeting." Hua Changqing still understood the truth. It was not good for the two of them to communicate in public in a high-end manner. He quickly turned to Mu Hengzhi and said, "Minister Mu, I think this path is feasible. We can go and have some contact."

"Yes." Mu Hengzhi nodded immediately, "Indeed, at the International Power Grid Conference, the people from the US Power Company also focused on future network security issues and specially introduced the concept of firewalls. In the long run, since it is a security issue, we need to pay attention to it."

Mu Zhiheng's voice fell, and as the meeting recorder's "swish" pen writing sound meant that the firewall became a real proposal, an urgent thing to do.

It is difficult for other people to interfere. They can only look at the inconspicuous undergraduate student in the back row with admiration. Whether it is a fool or a real skill, in short, this kid can scare Hua Changqing, in a sense, is already the most powerful person in this room.

As for Lao Zou, he has been alive for more than 60 years. He will not be unable to understand the minister's attitude. At this time, it is hard to say anything more, so he can only breathe in place. But it is difficult for him to blame Zhang Yifu, who caused the instigation. This kid has a very good attitude and speaks very well...

"Dear leaders, I have some ideas..." Zhang Yifu looked at Mu Zhiheng and Hua Changqing with advice.

"It's a big deal." Mu Zhiheng will definitely not underestimate the technicians of this power plant and listen with his ears.

"The second improvement plan is for this accident. Monitoring crash cannot directly lead to tripping. The direct reason is that the monitoring crash and the grid connection command signal disappears, which is equivalent to issuing a shutdown command to all units. I have roughly studied the monitoring system of Jiudan and found that the grid connection signal of the unit is completely controlled by the monitoring system. That is to say, once the monitoring problem occurs, the entire factory unit will have problems. As for the matter, I think under the existing technical conditions, we can add a way to convey the grid connection signal, that is, to introduce the switch status quantity, and communicate it to the unit alone without the monitoring system. In this way, even if the monitoring system is paralyzed, the unit will not lose the grid connection signal. It can continue to operate normally according to the power value before the monitoring failure, and at the same time send an alarm signal, so that the staff can handle it in time."

The concept of firewall may be somewhat high and low, but the switching state quantity is undoubtedly more down-to-earth. Simply put, these are the two numbers "0" or "1". If the unit receives "1", it is equivalent to receiving a grid-connected signal and continuously working.

Some engineers who have studied automation immediately began to think about the feasibility of this solution.

The switch status quantity and monitoring system are used to work together, and the grid-connected power generation of the control unit is simply the norm in 20 years. It is not that these engineers in front of us are stupid, but they are just that the automation knowledge is too classic.

There is a saying that it is understandable if you have a little bit of knowledge. Everyone is engaged in technology, and their education is both undergraduate and master's degree. For them, the inspiration brought by "introduction of status" is actually not more complicated than saying "adding an oil tray" to Niu Dameng. The engineers immediately began to communicate with the left and right, and told the solutions they thought were feasible.

This switch status can be operated manually and is very simple. It only requires a data channel to be completed. Even if the monitoring crashes, it can ensure the unit operation. The real double insurance is the only way to do the power generation of the unit. However, the unit's power generation power cannot track the dispatching commands in real time, but it is also temporary. As soon as the alarm is issued, the duty officer can immediately resume manual operation.

Such a practical improvement plan accidentally opened up the thinking of the technicians, and the atmosphere in the entire venue was also inspired. At this time, Zhang Yifu could sit down silently with satisfaction. The seniors in front of him were full of wisdom and only needed a light push.

At this time, Mu Hengzhi on the main seat finally showed a look of relief. This is the technical seminar, which has nothing to do with factions or interests. We should discuss technical issues and propose solutions in a practical way.

He asked casually: "This concept of switch state quantity seems to be more down-to-earth."

"I have limited understanding of the issue of automation, so ask Chinese workers." 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, in the United States, I have never heard of using switch status quantity to achieve dual insurance for grid-connected signal... This is really a... simple and innovative concept... It is so easy and practical, why no one thought it out? This technician... is really a bachelor's degree? He works 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, Zhang Yifu, who just graduated this year."

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

"Wait!" Hua Changqing exclaimed, "Zhang Yifu... Zhang Yifu... isn't that... the answer sheet!!"

"Director Liu's answer to the graduates' inspection, let them look forward to China's power industry 20 years later." Hua Changqing's excitement was already beyond words, "I never thought that I would meet him here, I never thought that I could be so soon!"

Mu Hengzhi and the Director of Safety Supervision next to them couldn't help but look at each other.

A young man who makes Hua Changqing so interested... must be not simple.

First, Duan Youwei's recommendation, then Hua Changqing's appreciation.

In addition, he also talked about real things in the conference room, opened up the experts' thinking and promoted the rhythm of technical discussion.

Mu Hengzhi narrowed his eyes and looked at Zhang Yifu, who had already sat down silently, and had a deep understanding of his achievements and reputation. Looking at the young technician of this large power plant, it was difficult not to feel a sense of appreciation.

He is not as crazy as Hua Changqing, and knows the worldly style. He stops at the same time and is willing to commit himself to the power plant. He has never seen such a talent and age in his life.

Since the founding of the People's Republic of China, in order to cultivate talents, we have done everything we can to study in the Soviet Union, the United States, and Japan. Generations have gritted our teeth and persevered, nodded and returned from studying... Finally, today, at this moment, we have begun to bear real fruits.

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

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

You have made a contribution, too.

But the future belongs to him.

Mu Hengzhi's imagination has been discussed in a hot topic.

"Now we have ready-made switching state quantity control devices. In fact, this method is used in many power plants. It is just because Jiuzhan is engaged in monitoring automation, so it is useless."

"Yes, the transmitters are all ready-made, and you only need to control them together with two sets of methods."

"As long as there is a set of signals that meet the conditions, it will be connected to the grid."

"This two-pronged approach will make Americans not afraid of tripping even if their software is completely paralyzed."

Everyone's words and words are like enlightenment. Once the thinking is unfolded, this question is simply too simple, even simpler than a oil pan.

Their negligence before was indeed a reason. Chinese people like to go to extremes when doing things, and too much is not enough. They say that they are conducting automation pilot projects and controlling all software, so they handed everything to the software and used the most automated way to do the Jiutan Power Plant. In fact, a few of the details only need to be slightly adjusted to reduce the losses caused by paralysis of the automation system.

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

"Old Duan, you are crouching tigers and hidden dragons in your factory."

"Our thinking is rigid, but I didn't expect that the comrades in the power plant would have such clear ideas."

"Yes, graduates are really amazing nowadays. The automation knowledge has been mastered to this level."

"It has to be the major of our Northern Electrical Institute."

"That's right, when it comes to power systems, they are really no worse than Tsinghua University."

Almost half of everyone present were from the Northern Electrical Institute. After all, 50% of the people from the Tsinghua Motor Department went abroad, 15% went into business, and 15% went to school. The remaining little bits left in the power system were mostly going to work in the power system, and few people were engaged in technical work in this venue.

Several major power colleges in the country are the mainstays of transporting talents to the power industry. With so many people sitting in it, a considerable number of them are Zhang Yifu's alumni.

As the topic changed, it turned into an exchange meeting of the Northern Electrical Institute. Everyone talked about the 1990 graduates and past events.

Mu Hengzhi felt helpless again in an instant. The atmosphere was too warm. It was like this when the meeting was held. Especially for meetings of this scale, it was simply too simple to run a topic.

However, he did not stop it. The agenda of the meeting has been basically completed. He was very satisfied with the introduction of two excellent solutions. In order to explore the application of firewalls, strategically increase security strength; in order to withdraw, only a small switch quantity can be introduced, which can actually eliminate potential hidden dangers.

It's already here, everyone is willing to talk, so let's talk.

After all, people who work in technology are still very different from those who work in power. They are more emotional and stubborn, especially when facing technical problems, they seek truth and truth, and often ignore the issues of interests. Fortunately, due to Zhang Yifu's outstanding performance this time, just like the "oil-holding pan" incident, the issues of interests and corrections have been perfunctory, and just list the solutions.

It was rare and everyone was happy. The so-called conservatives, with Lao Zou's silence and the introduction of their state, were nothing to say. Even the people who were about to bombard Hua Changqing's guns all at once, put down their sour mentality and started discussing happily.

Old Duan turned around silently, nodded deeply at Zhang Yifu, with a happy face. This was the result he hoped to see.

Zhang Yifu also nodded and replied, thanking the leader for giving him the opportunity.

He himself also knew that relying solely on his conceptual knowledge, the problem could not be solved directly. Whether it was introducing a firewall or introducing a switch state, it required a lot of complex work, and it must be completed by the engineers in front of him. Therefore, in the subsequent communication, he did not dare to be too ambitious at all. When faced with the problems and details thrown by others, he understood it, asked if he didn't understand it, and asked for advice. This humility was quite useful, making everyone feel that this technician was not as powerful as he could, and he also had technical weaknesses. He was also a person like himself.
Chapter completed!
