Chen Yanrui faced this problem, and after thinking about it, he still chose not to explain: "It is a comprehensive algorithm, and at the same time, the response time and so on need to be calculated, etc., cannot be given intuitively." ”

As he was talking, there was a new information import on the computer screen in front of Chang Jiang, and normal people would definitely not understand what the hell that pile of yellow English words was.

"It was an alarm, it didn't trip, but an alarm was issued. Changjiang operates while reassuring everyone.

Chen Yanrui also immediately squinted and swept to the electronic screen, and at the same time recorded quickly in his hand: "It's okay, it's normal, it's just a temporary small fluctuation, you should call the police, but it's not enough to trip." ”

Chang Jiang also glanced at the electronic screen, nodded and breathed a sigh of relief, the first reaction was normal, and at the same time he shook his head and smiled: "Mr. Chen, we don't need to record it like this, every qiē is recorded in the computer." ”

"Make a note of it yourself, it's practical, it's purely a habit. Chen Yanrui laughed at himself, "Old man, be tolerant." ”

"Hehe, nothing else. Chang Jiang pointed to the screen and said, "We may have to simulate like this for two weeks, and we will continue to simulate at night when no one is here, thousands of accidents, this is really not something that can be calculated by pen and paper, the core meaning of the computer is to free our hands and put time and energy into more important things." ”

Xiang Xiaofei stood behind and teased: "Why don't I think you two are liberated...... Isn't this still something to keep an eye on?"

"Isn't this just the beginning, fresh?" Chang Jiang laughed, "Look, two days later, no matter how he calls the police, no one will pay attention to him, just print out the report every day, and go back to analyze and study together." ”

Xiang Xiaofei didn't wait for him to finish, and suddenly pointed to the electronic screen and said, "Eh! This screen flashed!".

Sure enough, the bottom line of small English letters on the screen on the simulation instrument flashed, like the kind of flashing on an electronic watch.

"Beautiful!" Chang Jiang had already shouted at the screen. "I made a protective move two seconds ago, and the action time is ...... 8 milliseconds, outstanding!"

"Huh, this is done?" asked Xiang Xiaofei puzzled, "There is no intuitive reflection?"

"That's what relay protection is all about. Chang Jiang pointed to the bare machine not far away and smiled, "It's like a never-tireless sentinel." As long as there is a power supply, it will never stop, and every millisecond will be sampled, examined, calculated, and judged, for decades. And once a failure occurs, it will react within a dozen milliseconds to cut off the fuse of the accident. Much faster than a human reaction. ”

"It's getting better and better now. Chen Yanrui also sighed, "With this little thing, the accuracy, speed and reliability will be greatly improved, from the perspective of our product design, there will be infinite scalability in the future, such as the improvement of the algorithm, or the macro parameters of the power grid have been adjusted, we only need to upgrade the system version." It can solve the problem of upgrading. ”

"Teacher Chen, it will be even more powerful in the future. Zhang Yifu saw that the experiment was so smooth. He was also a little excited, and then generously stated, "With the rise of optical fiber communication and the improvement of network technology, it will be easy to establish a faster and more reliable communication channel between the protection of these lines, and constantly exchange data and check each other." At that time, the current differential protection will be the protagonist, and even if there is rejection, the backup protection will be added, let's call it ...... Cloud Protection ......

"Cloud protection?" Chang Jiang exclaimed, "What is this concept?" ”

All right. Zhang Yifu dug a deep pit for himself, cloud protection or something purely improvised, cloud eggs, isn't it the expansion of longitudinal protection, and he followed the IT operators in 10 years to make a lot of fun!

But Chang Jiang's curiosity obviously wants to dig into this pit.

"This ...... It's just a concept I'm imagining, based on Cloud-Computing, we can connect the information of every decentralized automation device in the power grid into a network through optical fibers, and they together interweave a piece of "cloud", you can imagine if all the devices create a communication channel with very low latency, sample each other, and assist each other in calculations, what kind of picture will it be?

Not only Chang Jiang, but even Chen Yanrui fell into a long-term sluggishness.

These two people already know the Internet and microcomputers very well, and their ideas are avant-garde enough, but after all their thoughts, they still can't imagine the picture described by Zhang Yifu.

Don't talk about them, even Zhang Yifu himself is not easy to describe, just a little pretending to force cloud computing, I didn't expect to arouse such a big curiosity between the two, it's not good.

"I can't understand that. Chang Jiang gestured and said, "Longitudinal protection is the most basic cloud protection?"

The principle of traditional longitudinal protection is actually distance protection plus the discrimination of communication signals, which is based on the number of communication, and the protection points at both ends of a line compare their respective numbers to monitor mutations and achieve protection.

"At present, longitudinal protection is point-to-point communication, which cannot be regarded as cloud protection, and the number of longitudinal protection jù interactions is too small, only those few parameters. "Zhang Yifu had to work hard to fill the hole," In the future, after the level of communication technology network technology and microcomputer hardware, a large number of fast data jù interaction will become possible, and this is not only between adjacent nodes, but the entire power grid, the fluctuation of the unit in a power plant in Xijiang can be instantly captured by all the surrounding nodes, the power plant substation carries out the overall calculation, and the whole network responds to this within tens of milliseconds, and sends a report, the dispatching duty room at all levels can get this report within one minute, immediately find out the cause of the accident, and call up the relevant number of the accident scene at any time in front of any computer, and the accident handling can be more accurate, quick ......"

Zhang Yifu followed his train of thought so nonsense, he felt as if he had discovered something......

Although the grid automation he knows is already very advanced, what he just said has reached the level of "intelligence", integrating the concept of cloud computing on the Internet, the entire power grid seems to have become a large computer, an extremely sensitive and complex brain, when any part of the body is uncomfortable, you can make decisions through the calculation of the brain.

Technically, this is not a fantasy, as long as there are enough smooth communication conditions, a genius enough software system, a fast enough computer, and a good enough digital sampling......

What the fuck is this...... Is it the future...... (To be continued......)
