Zhang Yifu was shocked by what he said, this concept may have been proposed, but he himself has never heard of it, purely out of the mouth, but after a little thought, this is more than ten years later, but it is not so fantastical, a magical smart grid......

His thoughts exploded like a big explosion.

Smart Meter ...... for Home Use Enterprise Electricity Monitoring ...... Real-time data analysis of microgrids, regional networks, and large power grids...... Intelligent Analysis, Load Forecasting...... Power generation plan, wind power consumption......

The distance between the units of the power plant and the electricity meters of thousands of households, which may be tens of thousands of kilometers, is connected by such a magical network in a dozen milliseconds.

"Shaw, this concept is still space-like. Chen Yanrui thought for a long time, but decided to pour a basin of cold water, "First, it is impossible for our communication channel to meet this number of interactions, and second, how can the CPU keep up with such a large amount of computing? And I really can't imagine how complex the core software system is, how can it be possible to hand over such an important thing to the computer?"

"Hmm......" Zhang Yifu didn't refute, you don't need to tell primitive people how amazing the fire gun is, this is really unrealistic for Chen Yanrui, just like the current people are obviously holding a brick, and the big brother who doesn't even have a text message function, no matter how you describe the smartphone to him, he can't understand why you pick up the phone in Jijing, you only need a very simple operation to see the video taken in Washington a minute ago.

The real smart grid only needs to be quietly brewed in your own mind, and it will take too long to do that...... But Zhang Yifu does not regret this, because that is the real challenge and direction, more than ten years later. After the knowledge of the predecessors has sent them far enough, they belong to their own challenge direction.

"It reminds me of Turing...... "the theoretical and practical founder of the modern computer, who assembled a large circuit board and performed binary calculations in order to decipher the Natsu code." After a few months of calculation, he really let him figure it out. Today's computers may only take a few minutes to calculate those things, and the concept that Shaw mentioned may take less than a second.

"Huh......" gestured to Xiao Fei, "It's just such a short time, although I can't understand what you say, it's very convenient." ”

"Maybe in a few decades, that's really the case. Chang Jiang immediately smiled and waved his hand. "But it's useless to think about it now, let's do a good job of protecting the microcomputer in front of us first. ”

"Hmm. Chen Yanrui also pointed to the instrument in front of him, "I just simulated a power grid oscillation, and the disturbance is relatively large, Changjiang, did you mismove over there?"

"Nope. Chang Jiang glanced at it and said with a smile, "This simulated power grid is too miserable, covering all the tragic accidents in the past 100 years." ”

"That would be great. Zhang Yifu pulled out of his thoughts and laughed. "If you go through all the accidents in 100 years, you don't need to update the software algorithm in 100 years. ”

"Haha. The premise is that our transmission equipment is not updated either. Chang Jiang laughed and asked, "By the way, I heard that you went to the Sanxi Demonstration Meeting? ”

"Yes, and the direct current transmission should be ahead of the Sanxi Dam unit for power generation. Zhang Yifu nodded seriously, "I have already thought about the tone of the power system leader. Something like that—"

As he spoke, he put on a stern and political expression, and said in a Ludong accent that was not very proficient: "Comrades, we must ensure the electricity of Sanxi." You can send it, you can drop it, you can use it!"

Chang Jiang and Xiang Xiaofei laughed on the spot when they heard this, Chen Yanrui couldn't help laughing, and praised again and again: "Yes, yes, the tone is like a minister." ”

It's simple, but it's anything but like that.

It is almost certain that this cross-regional long-distance transmission will use low-loss ultra-high voltage DC transmission, and it must be imported technical equipment.

That is, at the same time, it is necessary to establish a sufficient scale of hub substations and converter stations, to convert direct current into AC, and to change high voltage into medium and low voltage.

The regional power supply network has also kept up with the pace of construction, so that the vast water resources of the Yangtze River will eventually fall to thousands of households in more than a dozen provinces in the form of electricity.

How amazing physics is, the endless flow of the Yangtze River, can finally shine, you can cook, and you can even watch a movie.

In the process of chatting and laughing, the instrument simulated the situation several times, the test prototype responded uniformly and normally, and everyone gradually relaxed, this set of magical algorithms has not been fully understood by Chang Jiang so far, but it has proved that it is simply amazing, and now it is only 30%. If all the parts related to AC and DC ultra-high voltage and ultra-high voltage are written, and all the parts that are combined with communication automation are written, I really don't know what kind of effect it will play.

In his eyes, this is simply a huge wealth in the history of China's electric power, leaving the Electric Power Research Institute to engage in research and development in private enterprises, he was ready to lie on the salary for five or six years, but he did not want to be close to this treasure in a few months.

"Then we can count on the inside information. Chen Yanrui followed Zhang Yifu's speech just now, "Since the follow-up will be introduced through Guò Sanxi to introduce ultra-high voltage direct current transmission, then those projects of west-to-east power transmission will definitely be carried out DC." When the development of this model is completed, we will also follow the research and development of 330-500KV AC line protection and DC line protection. ”

"Not only that, if such a large-scale construction of ultra-high voltage DC, the demand for transformers and circuit breakers of the corresponding specifications is also huge.......

"Oh, that technology still needs to be provided by foreigners. Chen Yanrui hurriedly stopped this sign, "Let's first study the line protection thoroughly, and then the transformer protection, power generation protection, and automation system, this order, don't jump so far." ”

"Yes...... Chang Jiang scratched his head and smirked, "I just suddenly feel that there is not enough time at all, and there is no shortage of manpower, but there are too many things to do." ”

Zhang Yifu smiled with emotion, this is too right.

That's why we need you to create this golden product with a lot of profits, derive different models, and take the lead in dominating this market.

Speaking of being one step ahead, although Zhang Yifu didn't want to put pressure on them, he couldn't help asking: "Mr. Chen, if this simulation is real, what steps will be taken before the product is launched?"

Chen Yanrui's expression tightened a little when he heard this, and he looked back at Zhang Yifu: "Yifu, don't say that I poured cold water on you...... The success of this test can only say that our software system and acquisition device are no problem, and our main work is to package products in the industry, assemble signal outlets, man-machine panels, machine shells, etc., I know what you want to ask...... This series of work is the fastest and fastest, and it will take a month to produce a real test prototype, which will go through three long steps before it is listed. ”

Chen Yanrui said and raised his hand and said: "They are the real moving model, the type test and the trial operation, these three steps are not led by us, but done by the power system." The dynamic model test is similar to the test we are doing now, but it is not carried out under digital simulation conditions, but in the test environment of real generators, transformers, and transmission lines. The type test is to test whether the product can work normally under various temperatures, humidity, vibration and other conditions, as well as the test of damage and life, which are essential tests. These two tests have to be sent to the Electric Power Research Institute to do, and in the end, only when these two tests are passed and approved by the authoritative department can they be put into trial operation. We need to contact the leaders of the power management bureau, ask for their consent, provide our products to the power grid for free, trial operation for one and a half years, if the reliability is no problem, and then submit the product trial operation report to institutions and experts for comprehensive evaluation, a qiē shun lì, before it can be published. ”

Compared to R&D, these things are really troublesome......

Chang Jiang helped Zhang Yifu and asked, "Mr. Chen can find a way to try out that piece, right?"

"Well, I can figure it out with Chang Chang and even Shaw. Chen Yanrui nodded, patted his face and laughed at himself, "The state also encourages such trial runs, otherwise there will be no way to develop the industry, and as for the potential risks it brings, we can only rely on our old faces to settle it." ”

"How long did the first two tests take?" Zhang Yifu asked next.

"I know this, I came out of the Electric Power Research Institute? Chang Jiang immediately said, "Conventional relay protection, one month is enough, but we are the first microcomputer protection, the power research institute has not done this test before, this is probably an uncertain factor, at the same time, it is best to invite several authorities in the industry to come forward, together with a reliability report, the power grid only dare to test operation." ”

"Is there an industry standard for microcomputer protection now?" Zhang Yifu asked again.

"Yes, there is a ...... The ...... used to standardize the protection of imported microcomputers," Chang Jiang muttered, "according to this standard...... We must have no problem with the software system, it is the final product ......"

"Absolutely. Zhang Yifu said with a smile, "That is our minimum standard, I dare not say anything else, microcomputer protection and automation, we can catch up within three years." ”

"That's it. Zhang Yifu took a deep breath and began to point out, "We have limited experience in the industrial design of products, so we can find other schools or manufacturers to cooperate, as long as the confidentiality of our products is guaranteed." Try to complete those tests as quickly as possible, and I will also say hello to the trial run and try to ......"

Zhang Yifu was just about to get to the next point in time, but then he shook his head and forgot it, don't give this kind of pressure, a few people have already worked so hard, there is no need to impose their attitude of catching up with time on them, they are already very good.

"Next year. Chang Jiang gritted his teeth, and before he knew it, he began to catch up with time, "Let the product be launched next year." (To be continued......)
