Obviously, such a discussion will not lead to any substantive results, and the end result will be that another standard study report will be produced at the following academic committee meeting to continue the discussion.

Subsequently, just after the end of the standardization report, it was Zhang Yifu's turn to make a report, "The Application of Fieldbus Technology in Power Automation", what a timely situation, Schroeder, do you want to be more obvious!

Zhang Yifu took a deep breath and began his own report, since it is a special invited report, he must show some level and talk about some dry goods, otherwise he will lose China's face.

He first said the metaphor that has always been the case, the current power automation system, like a bunch of messy building blocks, hard to stick them together, and the bus, is the future of the organic link between each building block of the bridge, the previous standardization discussion has also been said, reasonable communication standards are the top priority, as the first to take thermal control, electrical full automation, the use of a comprehensive field bus operation of E1, I to talk about ideas and experience, I hope to do a part on the road to unified automation standards.

Zhang Yifu came in from a very shallow point and gradually went deeper to talk about his own views.

The report is divided into three tiers.

First, why should it be realized?

Second, how to achieve it?

The third is how far we have achieved.

Most people did not take the Chinese deputy's speech seriously, but after reading the agenda of the meeting, they felt that this Chinese was forcibly moved by some guy to help and make trouble, but the more they listened, the more they felt deeply.

Not for anything else, but they didn't participate in the E1 evaluation, and they didn't mention Zhang Yifu's whimsical ideas, the key is that they have almost achieved it?

This is really ahead of the world level.

How is it possible for someone to stand on top of the world as soon as they lift their feet?

So at first, most people think that this person is here to fool around.

However, the more I listened, the more true it became, and Nima talked about the details in great detail. If you follow this line of thought, everything seems to be really fine, why didn't we use Ethernet earlier! And how do your algorithms and programs keep up?

More people began to record, think, and hold back questions.

Zhang Yifu also came prepared, and showed the IEC evaluation report at the appropriate time. and the official evaluation, this is deliberately asked by Schroeder, in order to be afraid that sometimes, others will not believe him without evidence, and he must have an authoritative seal.

Everyone carefully examined the picture on the projector, and only then did they really pay attention to Zhang Yifu and his speech, he can talk empty, IEC is rigorous, no dry goods. It is impossible to produce such a report.

Some of them also noticed that Zhang Yifu's so-called realization was only a basic realization, and that the E1 system had never been implemented in any power plant or substation at all, everything was in theory and in the test environment, and the IEC evaluation was clearly "in experiment", not "in practice".

Of course, there is no need to question this. It's a place in itself that's the most avant-garde, cutting-edge technology exchange. What is needed is to throw stones to ask for directions, guide the way, and open the way.

Zhang Yifu's report was finally implemented on E1, and now Hengdian has also participated in the design of the Beidesert Power Plant, cooperating with ABB Siemens and other manufacturers in the construction stage. There will be a lot of unification, and in the follow-up actual automation construction, there is also a unified plan, and some equipment is difficult to unify the interface, which is also in contact and discussion. However, the most critical communication problem, PRO has been perfectly solved, he also follows the IEC communication standards, in the future automation standard development process, whether it is the first large-scale application of PRO in power automation, or the completion of Hengdian's E1 system, there will be a certain reference significance.

At the end of the speech, everyone did not speak for about half a minute, basically digesting what he said.

In fact, some people have put forward these ideas a long time ago, but the technical environment at that time was not satisfied, and even now it may not be satisfied, otherwise Siemens and the like would have done it a long time ago.

But now a Chinese person says that he has strung all these things together, and he has said it in a similar way, and many details and solutions are instructive, which is really incomprehensible.

It is better to ignore the fact of "China" for the time being, put down this layer of colored eyes, and try to accept and study this report as if it was said by a leading country in technology.

One of the members sitting at the front took the lead in raising his glasses, looked at Zhang Yifu's conference name tag and said, "What Mr. Zhang said is very good, unfortunately we have not had the opportunity to see the prototype of E1, is anyone lucky enough to participate?"

Schroeder raised his hand at the same time as the Canadians who were present at the time, and then Schroeder motioned for you to say, I won't say anything.

The Canadian nodded, "I was there at the time, and the E1's performance was really amazing, even if it was only in the lab, but the excellent system performance has been confirmed." When it comes to the actual construction, many hardware equipment Hengdian will take the import method, cooperate with major manufacturers, in the instructions at the time, a feasible solution has been given, as for the key point of the report - fieldbus technology, before E1 is put into production, it is indeed impossible to draw an effective conclusion. ”

"Yes. Zhang Yifu said with a smile, "Although I am 100% confident that all the design difficulties have been overcome, whether the PRO bus standard can be supported efficiently and stably still depends on the effect after it is put into operation." ”

"Please rest assured of this. Schroder hurriedly said, "The PRO standard has rich and comprehensive application experience and foundation in industrial control, which is fully enough to support the power generation industry." ”

"I'm more concerned about the E1 system itself. Another member said bluntly, "This is too groundbreaking, and China's power plants are already in the construction stage, and you can see such a system in more than a year, whether it is Hengdian or the managers of Chinese power plants, it is too bold." ”

In academic exchanges, the environment is better, there are not so many doubts or contempt, most of them are admiration, and the wording is also "courage", not reckless.

"Thank you for the compliment, but I deserve it. Zhang Yifu also immediately became humble, "According to my original intention, I should have made this kind of report after the E1 was put into production, but this time I was invited, and I was afraid that everyone would think I was ...... before I came."

Zhang Yifu said, unable to think of what words to use, and hurriedly asked Qiu Qiang beside him: "How do you say 'bragging'?"

"......" Qiu Qiang is really difficult, the translation work is too torturous, but she still quickly said, "Bragging." ”

"Yes, Bragging. ”

Everyone laughed, and his English wasn't as good as the report sounded.

Zhang Yifu also laughed at himself: "My English teacher asked for $80 an hour, and I couldn't afford to hire it, so I begged this lady to be my translator for the time being." ”

There was another burst of laughter, and everyone was closer. Zhang Yifu does not have the overly serious and rigid attitude that Chinese participants often have, and in addition to his professionalism, he gives people the feeling of a sunny young man.

Soon, some people began to ask some incomprehensible details, and Zhang Yifu also answered them one by one, mainly focusing on complex control, including load, steam pressure, speed, water level, etc., which requires real-time analysis of a large amount of data, which will cause a sharp increase in the amount of communication.

This was naturally something that E1 had in mind during the design phase. Different from the traditional practice of moving the control and processing functions down to the site, due to the interconnection between the various subsystems, it will lead to the trouble of communication surge, Hengdian will adhere to the consistent concept, integrated control, and solve and analyze these problems in the "brain" through PRO and TCP/IP communication protocols.

The problem is that communications are blocked.

So Zhang Yifu had to talk about the design of redundancy......

endlessly, Zhang Yifu's report has far exceeded the planned time, but no one has stopped it, even the host has ignored the time. This is the academic discussion, the atmosphere is very free, and there are no too rigid requirements and purposes.

Zhang Yifu naturally didn't dare to just play tricks on himself, and led Hu Haitao out many times and asked him to talk a few words, so as not to make this leader look particularly soy sauce.

At the end of the half-day exchange, the following agenda had to be postponed.

At lunchtime, Zhang Yifu observed an interesting phenomenon, that is, the participants of Xianggang and Wanwan deliberately kept a certain distance from the mainland, and Xianggang still had reason to hug the thighs of Britain and the United States and communicate more with the others, while Wanwan was closer to the Japanese, and only two or three participants simply sat with the Japanese team.

Zhang Yifu originally wanted to pull Hu Haitao over to talk about getting to know him, for him, this is an opportunity for more people to realize Hengdian microcomputer protection and E1, and the Hong Kong and Taiwan markets are just a breakthrough point before the official export, and it must be easier for a family to chat.

Hu Haitao has no interest in this, most of the Chinese delegation, including him, have very limited exchanges with Hong Kong and Taiwan, mainly because the people in Xianggang and Hong Kong look down on this side and don't want to be bored, and they have a relatively deep political relationship with Wanwan, for fear that there will be problems if they talk too much, he also advised Zhang Yifu not to talk too much.

Zhang Yifu is right to think about it, whether it is capital or technology, the power industry in Xianggang is absolutely dependent on the British system for the time being, and due to its own geographical reasons and poor energy distribution, the power generation system is more inclined to learn from Japan, nuclear power has become the mainstream direction, almost all imported Japanese equipment.

The family market is not so easy to get into.

Hu Haitao is also right, communicating with Wanwan is more awkward at the political level, although it does not rise to the level of politics of national events, but really in terms of power system technology. Imagine that the energy supply in modern warfare is almost the grain and grass in ancient warfare, and whoever can destroy the opponent's power grid is equivalent to almost cutting off the opponent's logistics production. The mainland is okay, Liaoyuan is vast, but the bend of the island has always maintained a sense of crisis, unwilling to disclose too many power details, this mood itself will cause a huge gap to the technical exchanges between the two sides, as for the microcomputer protection and automation system, they naturally dare not use the mainland brand.

After thinking about it, Zhang Yifu still gave up this plan, follow the organization, and don't make more trouble. (To be continued......)
