this man is not calm

Chapter 412 Reserve Force
The answer did not seem to be beyond Jin Shang's expectations.

"This is just a difference in size and strength. There is no difference in essence, right?"

"If you insist on explaining it this way, it is indeed true."

High-voltage direct current transmission technology, in fact, is the later ultra-high voltage technology. The communication HVDC power management system is only used in specific fields. In the future, with the development of new energy technologies such as photovoltaic and wind power and the large-scale deployment of distributed power sources, and the development of urban smart grid transmission systems, the application of flexible DC power supply networks will become more and more extensive.

Strictly speaking, the first model is only medium-voltage DC, which solves the problems of flexible interconnection, resource sharing, and safety and reliability of data centers in the power distribution link. It is only an internal transformation of the entire data center service system, which is more of a commercial behavior.
The second model goes a step further and tries its best to meet the requirements of green, low-carbon and environmental protection by greening power sources and optimizing transmission methods. It is clearly the future development direction.

There is no need for deliberate verification. Jin Shang can think of the application scenarios of this high-voltage direct current transmission technology. Energy and load are often mismatched. The proposals of super-large projects such as West-to-East Power Transmission, East-to-West Computing, and South-to-North Water Diversion were all born to solve practical problems.

In most cases, electricity consumption centers are not located in power generation centers. With the continuous advancement of urbanization, the requirements for power supply networks are becoming higher and higher, and there are more and more application scenarios for distributed power sources such as wind power and photovoltaics, thus giving rise to the third model.

The interconnected urban DC power grid will flexibly connect the city's massive regulating resources, such as distributed photovoltaics, wind farms, energy storage, charging piles, new energy vehicles and battery swap stations, to create a new customized data center that is 100% driven by green energy. It will also serve as an important subsidiary network for emerging energy flexible regulation resources to help the city's new energy municipal administration.

Of course, this thing looks beautiful, but it involves many areas, and it is currently only in the stage of conceptual design and planning sketches. I guess not many people who are working on it think it will be realized.

Only Jin Shang can see it with a forward-looking perspective. This is not some unrealistic science fiction fantasy, but something that will actually happen in the near future.

Undoubtedly, the most suitable scenario for the use of this new power grid transmission system is actually isolated areas like the Yongdong Islands that are isolated from the main power grid. The use of thermal power generation such as diesel and coal is costly and also produces pollution. There are some wind power and photovoltaic resources, but they are not very stable. It is somewhat unrealistic to establish a traditional AC power grid. A simple flexible DC transmission network is very suitable for this scenario, supplying power at a lower cost without considering too many technical difficulties.

Speaking of isolated islands, aren’t companies like Jin Shang and Jin Xi Culture, which are committed to building a self-sufficient integrated operation model and even want to build a self-reliant data center system that tries not to have major adverse impacts on the outside world, exactly the same?

Once the data center, industrial park, residential life system, commercial center, and other application areas are built, it will become a self-sufficient urban sub-center.

With the current development status of Beijing, the development of the central urban area is relatively complete and there is not much room for intervention. The western Beijing area is also developing rapidly and is busy with land grabbing. If you want to do something, you really have to take everything into consideration. The construction of a modern living area is inseparable from the organic combination of water, electricity, coal, three connections and one leveling, travel, transportation, food, clothing, housing and transportation, and all of this is inseparable from the most fundamental energy supply.

With electricity, shopping malls can operate, and mobile phones, household appliances, public transportation, street lighting, etc. can be used.

Why is it so difficult to build Jinxi Culture’s data center? Isn’t it because of the power supply problem?
If there could be a complete system to support the pace of cultural expansion today and tomorrow, it would be a huge boost.

In the current era of insufficient supply and surging demand, there is still hope to build a self-contained energy system around the capital. However, after a few years when urban construction is completed, it will be difficult to start a new system.

There is no chance in Beijing, so you can probably only develop in second- and third-tier cities around the capital, or in cold and harsh regions such as the Northeast and Beihai.

To put it simply, it means establishing private plots, consolidating the foundation, building a basic base, and using it as the main base to continuously expand the territory.

If we don't take advantage of the current good opportunity, not to mention our hometown in western Beijing, even the territories in the suburbs will be snatched away by others.

For other entrepreneurs, perhaps it is just a matter of changing places to develop, but Jin Shang is different. With the blessing of the ancestral golden finger of "Golden Broom", the larger and more complete the system is, the more it can exert its terrifying amplifying effect.

"No wonder...it's another godsend opportunity."

What is a local tyrant? Only those who have their own base are called local tyrants. Just playing around with IT and the Internet, expanding channels, building warehousing and logistics, and creating a network of relationships are all too empty.

Why doesn’t Jin Shang’s career plan include a career in politics?
Under the current model, if you don't reach a certain level, the role you play will be very limited and the scope of influence will be small. For the "Golden Broom", the effect will be limited. Even if everything goes smoothly and you become a powerful figure in the system, you have to be at least 40 or 50 years old. You have to wait a lot. The young Jin Shangke is unwilling to spend half his life on this.

In contrast, although the influence of business has its limitations, it can easily go beyond the circle. It has a certain degree of control not only locally, but also domestically, and even abroad. Isn’t that the case with those large multinational companies and super conglomerates?
Instantly, the word "energy" came to Jin Shang's mind, causing him to palpitate. The energy of the "golden finger" that was imperceptible to outsiders continued to surge, proving that the host's guess was correct.

The history of human development is the process of improving energy efficiency. Especially in the modern information society, the impact of energy has penetrated into all aspects. The mastery and utilization of electricity largely determines the prospects for future development.

"We will use this communication HVDC power supply technology. This is just the first data center and our first foray into the energy and power sector. There will be more to be built in the future. We can't go through so much trouble every time."

What data center? It's just an excuse. Jin Shang has long wanted to join forces with his second uncle Mei Yingnian, second uncle-in-law Zhang Hua and other allies to jointly develop a plan similar to the sub-center of the capital's remote urban area.

Relying on natural development to move forward step by step is too slow.

It is always inconvenient to use someone else's car, so it is better to start a new business and "create something new". To put it bluntly, although real estate, the Internet, electronic equipment and the like can make money, they are too superficial.

The term "new rich" is actually a nice way of saying "nouveau riche". Look at what the "old money" are doing.
How can there be a conglomerate that doesn’t even get involved in energy?

It's fine if you don't have money to play, but if you have money, you should act quickly. Once the market is saturated and the gaps are filled, it will be a waste of time and effort if you want to get involved.

Now that the general direction has been decided, the details can be improved by the employees. Since a modular customization strategy is adopted to reduce costs and area requirements, the data center can be opened first and then gradually expanded as needed.

The previous idea of ​​achieving everything in one step is actually unnecessary.

Only by building it and putting it into use can everyone feel its usefulness and ease the resistance to expansion. Many high-tech technologies in the next 20 years were not mature until the late 1980s and early 1990s, just like today's lithium batteries, which seem to have a bright future, but in fact have very unsatisfactory results.

The weight reduction and miniaturization are not up to standard, the safety issues have not been resolved, and the conditions of use are still very harsh. The mainstream on the market is still the stable and reliable lead-acid battery. Although this thing has a short service life, it is cheap, has a high recycling rate, and can be recycled, which is also very cost-effective.

As for lithium batteries and the like, the price-performance ratio of new products is very poor, and there is currently no value in secondary recycling.

After the technical meeting, Jin Shang and several key persons in charge went to see the customized products commissioned to the electromechanical equipment company for development.

The first is the key product, which is the maintenance-free battery with a fully sealed structure and modern technology that was recently launched. It is the classic lead-acid battery, which is widely used in energy storage devices of uninterruptible power supplies such as UPS, ATS and HVDC.

According to marine electrical engineers, lead-acid batteries are backward and heavy, but they are very practical, especially for marine equipment energy storage devices. Lead-acid batteries are the mainstream. They are safe and reliable, have strong anti-interference capabilities, and have loose operating conditions. They are very suitable for use in harsh working conditions such as at sea.

This visit made Jin Shang understand why, even after 30 years, lead-acid batteries have not been replaced by lithium batteries, air batteries, hydrogen energy, etc. The bottom line is that lead-acid batteries have superior floating charge performance, far exceeding emerging energy storage modes such as lithium batteries. They are very useful in continuous, constant-voltage charging, and are the most cost-effective in telephone exchange stations, backup power supplies, and high-frequency compensated charging and discharging.

Of course, lead-acid battery packs are only the last iron gate for power supply safety. Large-capacity energy storage still requires liquid flow redox or pumped storage, and lithium batteries are also one of the development directions.

In the past, Jin Shang felt that the more high-tech the technology, the easier it was to use. However, in many fields, especially the power supply field with high requirements for safety, reliability and stability, many mature old technologies are more popular and will not be completely eliminated.

CSSC Electromechanical has been deeply involved in the marine equipment market for many years and has some experience in durable electrical machinery equipment.

In addition to batteries, we also have some technical reserves in the fields of fans, refrigeration and air conditioning, and water cooling systems.

Jin Shang thinks this indirect evaporative cooling system in front of him, which is as big as a standard container and specially customized for data center rooms, is very good. It is definitely not as convenient as a conventional air conditioner for frequent starting and stopping in a short period of time, but it is very useful for data center rooms that are turned on uninterruptedly for a long time and have strict requirements on indoor temperature and humidity. It is not only energy-saving and electricity-saving, but also can be customized in standardized modules, easy to transport and install, and saves space.

The air inside and outside is isolated, and its core components are the heat exchange core, natural cooling, fan cooling, spray evaporation, compressor supplementary cooling, and multi-stage refrigeration mode, which are still very attractive.

The only thing that makes people concerned is that this multi-stage cooling mode consumes a lot of water. Fortunately, the practical technicians said that it can use preliminarily filtered urban sewage, recycled water and even seawater and other fresh water that is far below drinking grade.

This adds a lot of added value to this indirect evaporative cooling system.

Next, based on the customized product design plan sent by Jinxi Culture Headquarters, the Mechanical and Electrical Company produced two decent products in just one quarter.

One type looks like a baseball bat stuck upside down in the ground. It is hollow inside and very light. A push or even a breeze will cause it to vibrate rapidly, driving the special power generation system underneath to convert mechanical energy into electrical energy.

Another type of fan looks like a large subwoofer, but it does not have fan blades inside, but instead has separate sheet-like membrane blades. When wind passes through the guide device, the internal membrane blades vibrate violently, and the central power generation system can convert this kinetic energy into electrical energy.

Ever since the discovery of electromagnetic induction, generators that convert mechanical energy into electrical energy have emerged in large numbers. There are all kinds of them. Wind turbines do not all look like large three-blade fans. With just a little modification, they can be transformed into a variety of shapes.

The two bladeless wind turbines in front of you with different shapes use the famous Karman vortex street phenomenon in classical fluid mechanics to produce violent vibration and oscillation effects. They are made of carbon fiber and glass fiber, with a lightweight body and internal elastic rods, which allow them to shake in wind speeds of three meters per second or even lower. The principle is similar to that of conventional AC generators. The eddy current will cause the internal turbine to oscillate between the coil and the magnetic field, generating electricity through electromagnetic induction without rotation.

Compared with fan-blade generators, bladeless wind turbines are very small in size, extremely light in weight, and easy to install. They save more than half of the installation and operating costs compared to traditional wind turbines. They have almost no requirements for wind direction during operation and can start generating electricity with a very weak breeze.

Although its power generation efficiency is nearly 30% lower than that of traditional wind turbines, it is still very cost-effective compared to its advantages.

Its lifespan is also quite long. Even in extremely harsh environments, it can be used for more than 30 years. If properly maintained, its theoretical lifespan is close to 100 years. This is exaggerated. The lifespan of a person from birth to death is not as long as that of an industrial wind turbine.

In addition, considering that it has no fan and occupies a small area, the columnar bladeless fan can be installed anywhere and can be arranged very densely. The noise is not loud, not exceeding 20 decibels. The guide tube-type blade-wing wind turbine can be placed in rows on the edges of roofs, walls, railings and other high places without affecting other buildings. It can also be used as a landscape and perfectly integrated into daily urban construction.

With this said, its advantages are obvious. Large, high-performance three-blade wind turbines have blades that are nearly a hundred meters long, which are difficult to deploy inside the city. The wind farm area required is extremely large, and the installation spacing is also not small, which will have an impact on the environment, and the low-frequency noise problem is difficult to solve. Therefore, they can only be deployed in remote areas with abundant wind resources. If the wind is slightly weaker, they will not be able to move.

The advantage of bladeless wind turbines is that they are not picky about location and do not affect daily urban life. They can generate electricity with just a little wind. Although their efficiency is a bit low, their lifespan is long, and a little accumulation is very significant. They are also very consistent with the promotion and development direction of distributed power sources, making perfect and efficient use of idle space in metropolises, and fully utilizing the locational advantages of every inch of land being valuable.

After trying it several times, Jin Shang was satisfied with this product and planned to find a place to test the effect. If it was good, he would roll it out on a large scale.

"Patents are applied for when they should be, and bonuses and subsidies for the R&D department are paid when they should be. It's already very good to have such results."

After making the conclusion, Jin Shang had a clear understanding of the capabilities of his employees.

Now the company is large and has many subsidiaries and grandchildren. If you look around, you will find some talent. The R&D capabilities of each business segment, although not top-notch, are at a decent level. Products that do not require too high standards can still be developed.

At least the performance so far is quite satisfactory. As for data center servers and high-end gaming servers, don't expect too much for the time being. It will be fine as long as they can be maintained well and all services can be used normally. We don't have the strength to develop products independently from scratch.
