"The short circuit operation time of line exit is up to 18 milliseconds? The shortest is only 10 milliseconds?"

"Yes, the average action time actually hit 15..."

"By accident?"

"It is stated above that it is the result of nearly a hundred trials."

"Looking at this point, the system oscillation test is zero?"

"...It's true that after simulating so many system oscillations, there was no mishap in one go."

"Not only that, there is no error in the absence of dynamic stability. Moreover, from the test report, 866a's warning codes accurately describe the system uneasiness 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. They can be called out at any time when doing accident analysis."

"This is microcomputer protection. There are too many performances integrated in a small device!"

While he was eager to try, Professor Li Minghe finally began to preside over the appraisal, and from beginning to end, he analyzed and discussed the experimental projects in turn. During this process, the Academy of Electrical Sciences also distributed copies of the test reports of the same type of line protection of Mitsubishi, ABB, Ge and Siemens. Finally, there were temporary common standards for microcomputer protection. This set of standards is not very mature. It mainly regulates foreign manufacturers and is basically set according to their situation.

A truly tense and meticulous discussion began here, and compared it with several major international manufacturers, comparative advantages and disadvantages.

In fact, there is no need to compare it. The advantages of 866a are clear at a glance. The data conclusions in various experiments are the most advanced. The core CPU and A/D conversion devices of 866a are all the latest. When the basic hardware has no disadvantages, the software algorithm is completely ahead of the way. After ten years of thinking and logic, it reinterprets the line protection. Unfortunately, the current hardware and program locale still cannot keep up with that concept, resulting in Zhang Yifu not taking out all the functions.

But these in front of you are enough to stand out.

Hua Changqing didn't listen to others' speeches at all. He just lowered his head and looked at it carefully. Compared with the tests of several major international manufacturers, he became more and more panicked. Zhang Yifu was right. 866a could not have been a scam from reassembling imported products, because his quality has surpassed any similar product on the market!

What surprised him even more or despaired was that due to the limitations of the Academy of Electrical Sciences' capabilities, some functions of the product cannot be tested now, such as the ability to simulate the transmission of fault information through line carrier signals, but does not have the ability to simulate fiber optic communication transmission signals, and for example, some low-probability fault settings, etc.

It can be said that 866a's product strength has completely surpassed the current power grid demand!

Hua Changqing's thinking had already come to a standstill. He thought it should be a piece of paper, a piece of cake and a piece of paper, and barely put into production, but he didn't expect it to have surpassed his own cognition, just like...

Just like the automation system design instructions in the safe.

Chen Yanrui could not have this strength. It would be good if he could ensure the most basic functions and stability of the product. It was definitely Zhang Yifu. Although he didn't know how he came into contact with the concept of innovative international level, in short, he did it. He was the real researcher and pioneer.

Then what am I?

Hua Changqing thought this way.

He has always been very confident that he has crushed Zhang Yifu in his vision, age, qualification, experience, and technology, so he confidently brought him into the group. Now it seems that Zhang Yifu really doesn't have this need, and it's hard for him to have anything that can attract Zhang Yifu. Instead, Zhang Yifu's things are very attractive to him.

Fang Siqi next to her was obviously not concerned with these reports, but the expressions of everyone present. She has definitely participated in many similar appraisal meetings, but she has never been so quiet once. Most appraisal meetings are formalities, and there is actually nothing new. People below chat and dozing off are common, and everyone in front of her was thinking about something, following Li Minghe's thinking step by step.

How can Changdian always make a fortune in silence!

It’s better to innovate any product if you want to play with your life!

"I'll leave first." Hua Changqing breathed a sigh of relief, put several reports next to him, but did not receive them in his bag, "There is no need to listen again."

Zhang Yifu shrank his legs happily, freeing up space for Hua Changqing to leave.

For these two people, they were basically nonsense for a long time, but Hua Changqing sounded like she was in a panic, and Zhang Yifu was just interested in it.

It was like Zhang Yifu designed a perfect chess game for a long time. Although he was confident and familiar with the direction of every step after the chess game started, he could appreciate this established process and the experience was still so wonderful.

As a person who is well versed in this, Hua Changqing has nothing more painful than watching others practice the perfect chess game. The communication between his peers should have been pleasant, but he can't be happy because of his pride.

"866a is very good, congratulations." Despite the unpleasantness, Hua Changqing maintained the decent she deserved.

"Thank you, and I wish your automation system to be released soon."

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

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

Hua Changqing left like this, without taking the test report, Fang Siqi took the opportunity to move aside and approached Zhang Yifu. Facing Zhang Yifu's vigilant gaze, she kept a safe distance and showed a unique slutty smile.

"whee."

"What a hell, I'm so idle lately." Zhang Yifu snorted.

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

"Stop asking." Zhang Yifu immediately stopped her bad thoughts, "Where did your attendance certificate come from? I'll accept it if you believe it?"

"Don't be so stingy! Anyway, if you have this mouth, you will give Jijing Hotel so much money! You'll just give you a meal in the future."

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

"By the way, let me tell you that we are no longer planning to poach your people in our internal discussion."

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

"There is also this factor..." Fang Siqi shook her head in pain, "After recruiting so many people, she is still preparing, preparing, constantly preparing, asking for money, and constantly asking for money. She has used a budget of half a year this month."

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

"Don't disgust me." Zhang Yifu waved his hand, "I know you have a strong foundation, so feed him slowly and prepare for three or four years."

"Don't scare me, no one can afford to feed me for such a long time."

"Why is scaring?" Zhang Yifu nodded at Chen Yanrui on the stage, "Who do you think is more suitable for being the boss?"

"Then you need to say? Aren't Chen Yanrui's current achievements all given by you?"

"It's really not. You look down on me too much." Zhang Yifu shook his head, "Professor Chen is very stable. He thinks much more comprehensively than me. Some details I missed are all made up for. He is also stable in character, so he hopes to protect the line without any unnecessary thoughts. Hua Changqing is not. He has eaten and seen something outside, and he is arrogant, has a big heart and too high. If he doesn't make so many products, he has to do power system automation as soon as he comes, and it involves too many things, and it's all new things. Look at him digging a doctorate in the east and a researcher in the west, and it seems that there are elites. In fact, it's not that anyone has made automation products, and everyone has to accumulate from scratch, and a bunch of academics can create such a large and complete product from the beginning? Just wait, it's good to have something in three or five years."

Fang Siqi answered Zhang Yifu in the most inexplicable way, and saw her holding her chin and saying seriously: "Brother Yifu is smart, and he has come to the point at once!"

"roll."

Lunch was a hearty buffet, and there was no rest after the meal, the meeting continued, and the atmosphere became more and more active. Personnel from all sides began to speak and ask questions. Most of the questions were technically. They were curious about how such advanced and stable performance was achieved. Chen Yanrui and Chang Jiang prepared before the meeting, saying what they could say, and fooling them if they couldn't say.

After the dynamic mold test and appraisal was completed, everyone was very sure that this was definitely a successful product. When the meeting was almost over, the reporters of the Electric Power News also arrived. They were willing to do so only when the appraisal was confirmed that there was no problem. Of course, the manuscripts and car fees from Hengdian were indispensable.

Finally, in the discussion of type tests, 866a finally exposed some problems. It will barely pass the tests such as temperature, humidity and heat resistance, electromagnetic compatibility, etc. The long-term harsh environment will have a significant impact on the device. In these high-voltage tests, the operation of 866a will have a certain deviation, which is obviously inferior to the four major import manufacturers in this regard.

The shortcomings in craftsmanship need to be overcome urgently.

Finally, Professor Li Minghe will conduct an appraisal summary.

Professor Li wore reading glasses and spoke in a visibly excited voice to read the appraisal conclusions passed by the appraisal committee members:

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

"The appraisal committee unanimously agreed that the 866a microcomputer line protection device has a reasonable design, advanced principles, complete functions, reliable performance, and easy to use. The overall technical indicators have reached the advanced level of similar international products and have good application prospects. The appraisal committee unanimously agreed to pass the appraisal."
