When Chen Yanrui faced this problem, he still chose not to explain after thinking about it: "That is a comprehensive algorithm, and it also needs to calculate the response time, etc., which cannot be given intuitively."

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

"It was an alarm, it did not trip, but the alarm was issued." Chang Jiang made everyone feel at ease while operating.

Chen Yanrui immediately narrowed his eyes and swept to the electronic screen, and quickly recorded it in his hand: "It doesn't matter, everything is normal, it's just a temporary small fluctuation. It should be called the police, but it is not enough to trip."

Chang Jiang also glanced at the electronic screen, nodded and breathed a sigh of relief. He was the first to react normally. At the same time, he shook his head and smiled: "Mr. Chen, we don't need to record this way, everything is recorded in the computer."

"Remember it yourself, be down-to-earth, it's purely a habit." Chen Yanrui laughed at himself, "Is it old man, be tolerant."

"Haha, there's nothing else." Chang Jiang pointed to the screen and said, "We might have to simulate this for two weeks. No one will continue to simulate at night. Thousands of accidents are really not something that can be calculated by paper and pen. The core meaning of computers is to liberate our hands and put our time and energy on more important things."

Xiang Xiaofei stood behind and joked, "Why didn't I feel that you two are liberated... Do you still have to stare at me?"

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

Before Xiang Xiaofei could finish speaking, she suddenly pointed to the electronic screen and said, "Hey! This screen flashed!"

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

"Beautiful!" Chang Jiang shouted at the screen. "The protection action was made two seconds ago, and the action time was...8 milliseconds, which was very outstanding!"

"Ah? That's it done?" Xiang Xiaofei asked in confusion. "No intuitive response?"

"Is it a flash of lightning? This is the meaning of relay protection." Chang Jiang pointed to the bare metal not far away and said with a smile. "It is like a never-tiring sentry. As long as there is power supply, it will never stop. Every millisecond will be sampled, examined, calculated, and judged, and it will be the same for decades. Once a failure occurs, it will react within ten milliseconds, cutting off the fuse of the accident, which is much faster than a person's reaction."

"It's getting more and more powerful now." Chen Yanrui also sighed, "With this little thing, the accuracy, speed and reliability will be greatly improved. Judging from our product design, there will be infinite expansion in the future. For example, there are improvements in algorithms or adjustments to the macro parameters of the power grid. We only need to upgrade the system version to solve the problem of updates."

"Teacher Chen, it will be even more powerful in the future." Zhang Yifu was also a little excited to see that the experiment was so smooth. With the rise of fiber optic communication and the improvement of network technology, the protection of these lines will be easily established to establish a faster and more reliable communication channel, and continuously interact with data and check each other. At that time, current differential protection will be the protagonist. Even if there is a refusal, backup protection will be added. Let's call it...cloud protection..."

"Cloud protection?" Chang Jiang said in surprise. "What is this concept? Tell me."

Well, Zhang Yifu dug a deep pit for himself. Cloud protection is purely improvised, cloud protection is just an egg. Isn’t it just an extension of the vertical protection? Isn’t it joining in the fun with the IT operators in more than 10 years later!

But Chang Jiang's desire for knowledge obviously needs to explore this pit deeply.

"This... is just a concept I'm thinking about. Based on cloud-computing, we can connect the information of each decentralized automation device in the power grid into a network through optical fibers, and they jointly interwoven into pieces of "clouds". Imagine what kind of picture would it be if a communication channel with very low delay was created between all devices, sampling each other's data, and assisting each other in computing?"

Not only Chang Jiang, but also Chen Yanrui was stunned for a long time.

These two people already have a good understanding of the Internet and microcomputers. Their ideas are already avant-garde enough, but after exhausting their thoughts, they still cannot imagine the picture described by Zhang Yifu.

Not to mention them, even Zhang Yifu himself is not easy to describe. He just pretended to be a little bit of a cloud computing. Unexpectedly, it aroused the two of them so much curiosity, which was not easy to accomplish.

"Can I understand this way?" Chang Jiang said with a gesture, "Dimensional protection is the most basic cloud protection?"

The principle of traditional vertical protection is actually distance protection and communication signals. It is based on data communication. The protection points at both ends of a line can monitor mutations by comparing their respective data and achieving a protective effect.

"At present, vertical protection is point-to-point communication, which cannot be considered cloud protection. Moreover, vertical protection data interaction is too few, only those parameters." Zhang Yifu had to fill in the pit. "In the future, after the communication technology network technology and microcomputer hardware level is improved, a large number of fast data interaction will become possible. Moreover, this is not just between adjacent nodes, but the entire power grid. The fluctuations of units in a power plant in Xijiang can be instantly captured by all surrounding nodes. The substations of each power plant perform overall calculations, and the entire network responds to this within a few dozen milliseconds, and sends a report. The dispatching duty rooms at all levels can get this report within one minute, and the cause of the accident is immediately checked. Data related to the accident site can be retrieved at any time before any computer. The accident handling can be more accurate and quick..."

Zhang Yifu followed his thoughts so nonsense, and he felt as if he had discovered something...

Although the power grid automation as he knows is already very advanced, what he just said has reached the level of "intelligence". Combining 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 discomfort occurs anywhere in the body, decisions can be made through brain calculations.

Technically, this is not a fantasy. As long as there are sufficiently smooth communication conditions, sufficiently talented software systems, sufficiently fast computers, and sufficiently complete digital sampling...
