"The maximum short-circuit operation time of the line exit is 18 milliseconds, and the shortest is only 10 milliseconds?"

"yes, the average action time is 15......"

"By chance, right?"

"It is the result of nearly 100 tests. ”

"Later, you look here, the system oscillation test, the error rate is zero?"

“…… Really, after simulating so many system oscillations, there was not a single mismovement. ”

"Not only that, there was no mismovement in the case of the loss of dynamic stability, but from the test report, 80% of the warning codes given by the 866A accurately described the system unsettling factors. ”

"Yes, dozens of system fault judgment codes are written on the product manual, which can be displayed on the electronic screen at that time, and the parameter records will be stored in real time, and they can be called up at any time when doing accident analysis. ”

"This is microcomputer protection, there is too much performance integrated in one device!"

In the process, the Electric Power Research Institute for Mitsubishi, ABB, GE and Siemens four copies of the test report of the same type of line protection were also distributed, and finally there is a temporary general standard for microcomputer protection, this set of standards is not very mature, mainly to regulate foreign manufacturers, basically according to their situation to set the standard.

A really intense and detailed discussion began, and at the same time compared with several major international manufacturers, comparing the advantages and disadvantages.

In fact, there is no need to compare, the advantages of 866A are clear at a glance, the number of conclusions in various tests is second to none, the core CPU and A/D conversion devices of 866A are the latest in the world, and the software algorithm is completely ahead of its time when the basic hardware is not disadvantaged. It took ten years of thinking and logic to reinterpret the line protection, but unfortunately, the current hardware and programming language environment still can't keep up with that set of concepts, and Zhang Yifu has not come up with all the functions.

But what is in front of you is enough to stand out from the crowd.

Hua Changqing didn't listen to others at all, but just lowered his head and looked carefully one by one, comparing the tests of several major international manufacturers. The more he looked, the more panicked he became, Zhang Yifu was right, 866A could not be a reassembly of imported products to deceive people, because his quality has surpassed any product of the same type on the market!

What surprised him even more or despaired was that due to the limited capacity of the Electric Power Research Institute, some functions of the product could not be tested now, such as the ability to simulate the carrier signal of the Tongguò line to transmit fault information in real time, but it did not have the ability to simulate the transmission signal of optical fiber communication, and then the setting of some small probability category faults and so on.

It can be said that the product strength of 866A. It has completely exceeded the needs of today's power grid!

Hua Changqing's thinking had come to a standstill, he thought that this should be a patchwork thing, like a cat and a tiger, and barely put into production, but he didn't expect that it had surpassed his own cognition, just like ...... It's like......

It's like the automation system design instructions in the safe.

Chen Yanrui can't have this strength, he can ensure the most basic function and stability of the product, it's not bad, it's definitely Zhang Yifu. Although I don't know how he came into contact with the concept of innovation on the international level, he did it. He is the real researcher and pioneer.

So what am I?

Hua Changqing thought so.

He has always been very confident that he has crushed Zhang Yifu in terms of vision, age, qualifications, experience, technology and knowledge, so he confidently pulled him into the gang, and now it seems that Zhang Yifu really has no need for this, and it is difficult for him to have anything that can attract Zhang Yifu, but it is Zhang Yifu's things that attract him.

Fang Siqi next to her. The attention is obviously not these reports, but the looks of everyone present, she has definitely participated in a lot of similar appraisal meetings, but she has never been so quiet, most of the appraisal meetings are going through the motions. In fact, there is nothing new, it is not uncommon for people below to chat and doze off, and in front of them, everyone is actually thinking about something, following Li Minghe's train of thought step by step.

How can Hengdian always make a fortune in a muffled voice!

It's better to sell than to innovate any product!

"I'll go first. Hua Changqing breathed a long sigh of relief, put a few reports aside, and did not receive them in his bag, "There is no need to listen to it anymore." ”

Zhang Yifu shrank his legs happily, making room for Hua Changqing to leave.

For these two people, it was basically nonsense for a long time, but Hua Changqing sounded like he was overwhelmed, and Zhang Yifu was just relishing.

Zhang Yifu seems to have spent a long time designing a perfect chess game, although he is very confident and familiar with the direction of each move after the start of the chess game, he can appreciate the established process, and the experience is still so wonderful.

And Hua Changqing, as a person who knows this well, has nothing more painful than watching other people's perfect chess game drills, and the communication between peers should be pleasant, but he can't be happy because of his pride.

"The 866A is very good, congratulations. Despite the unpleasantness, Hua Changqing still maintained the decency he deserved.

"Thank you, and I wish you an early arrival with your automated system. ”

Hua Changqing froze for a moment, and then looked at Fang Siqi: "You?"

"I'll sit down a little longer, I haven't eaten the buffet at the Jijing Hotel. Fang Siqi found a suitable reason to stay.

Hua Changqing just left, without taking the test report, Fang Siqi took the opportunity to move to the side and came to Zhang Yifu's side, facing Zhang Yifu's vigilant gaze, she kept a safe distance and showed a unique cheap smile.

"Hee-hee. ”

"Hey, I've been idle enough lately. Zhang Yifu snorted.

"Hey, who the hell is he?" Fang Siqi took the opportunity to aim at Jia Luansong, who was concentrating.

"Inquire less. Zhang Yifu immediately stopped her bad thoughts, "Where did you get your badge? Believe it or not, I received it?"

"Don't be so stingy! Anyway, with or without my mouth, you all have to give so much money to the Jijing Hotel! ”

"Don't worry, you don't have that chance. Zhang Yifu waved his hand and said, "Don't disturb me to enjoy the appraisal meeting." ”

"By the way, let me tell you, we are no longer ready to poach your people in internal discussions. ”

"Then I really have to thank you. Zhang Yifu sneered, "It's because the finances can't bear it, right? Hua Changqing's treatment is so high, and the money is like a strong wind." ”

"There is also this factor...... Fang Siqi shook his head bitterly and said, "After recruiting so many people, I am still preparing, preparing, constantly preparing, asking for money, asking for money, asking for money, and I have used half a year's budget this month." ”

After that, she said softly: "Just sue you, don't tell others that I am dissatisfied with him~"

"Don't disgust me. Zhang Yifu waved his hand and said, "Knowing that you have a thick foundation, feed him slowly, and be ready to feed him for three or four years." ”

"Don't scare me, no one can afford to feed me for so long. ”

"What's the scare?" Zhang Yifu snorted at Chen Yanrui on the stage, "Who do you think is more suitable to be the boss between him and Hua Changqing?"

"Needless to say, aren't Chen Yanrui's current achievements all from you?"

"Not really, you think too highly of me. Zhang Yifu shook his head and said, "Professor Chen is very stable, and his thinking will be much more comprehensive than mine, and some of the details I missed are made up by him." The character is also stable, and I wholeheartedly hope to do a good job of line protection, and there are no superfluous ideas. Hua Changqing is not, he has eaten and seen outside, his temperament is also proud, his heart is too big, the www.biquge.info of the pen fun pavilion is too high, so many products are not done, he has to come up to engage in power system automation, which involves too many things, and they are all new things, you see him digging a doctor in the east, digging a researcher in the west, it seems that the elite gathers, in fact, no one has ever done automation products, everyone has to start from scratch, little by little accumulation, a group of academic people will make such a large and complete product? You wait, it's good to have something in three or five years. ”

Fang Siqi answered Zhang Yifu in the most incomprehensible way, only to see her holding her chin and saying seriously: "Brother Yifu is smart, and he got to the point all of a sudden!"

"Get out. ”

Lunch is a sumptuous buffet, there is no rest after the meal, the meeting continues, the atmosphere is becoming more and more lively, all parties began to speak and ask questions, most of the questions are at the technical level, they are very curious about how to achieve such an advanced and stable performance, Chen Yanrui and Chang Jiang are prepared before the meeting, what can be said, what can not be said fooled over.

After the identification of the dynamic model test, everyone is very sure that this is definitely a successful product, and when the meeting is about to end, the reporter of the electric power newspaper also came, and they are willing to go out only after confirming that there is no problem with the identification, of course, it is indispensable for the constant power to supply the past manuscript and the carriage and horse fee.

Finally, in the type test discussion, 866A finally exposed some problems, in the temperature, damp heat resistance, electromagnetic compatibility and other tests will barely be qualified, long-term harsh environment will have a great impact on the device, in these high-voltage tests, 866A operation will have a certain deviation, in this regard is obviously inferior to the four major importers.

The shortcomings in the process need to be overcome urgently.

Finally, Professor Li Minghe made an appraisal summary.

Professor Li wore reading glasses and read out the appraisal conclusions of all the appraisal committee members in an obviously excited voice:

"Today, organized by the Relay Protection Professional Committee of the Society of Electrical Engineering, in the appraisal meeting of the '866A microcomputer circuit protection device' developed by Hengdian Technology Co., Ltd., the appraisal committee listened to the development report of the 866A line protection device, and the technical and economic analysis ............"

The appraisal committee unanimously agreed that the 866A microcomputer circuit protection device is reasonable in design, advanced in principle, perfect in function, reliable in performance, easy to use, and the overall technical indicators have reached the advanced level of similar products in the world, and has a good application prospect. ”

The applause sounded again, the front is all nonsense, the last sentence is the most important, every word is worth a thousand gold, which indicates that 866A can be put into production and used, as the only product of domestic microcomputer protection, after the identification of experts in the most authoritative department, the policy and market behind it are almost unimaginable.
