Chapter 1306 The Song of Electricity ([-])

He saw that last night several Dianlikou elders who continued to discuss the content of the meeting last night, who were supposed to have a drink in the farm tea house, were also sitting at the conference table in high spirits at this meeting.I am very happy.He cleared his throat and said: "You may already know that with the efforts of Elder Faraday, the Senate's first self-developed and produced practical motor has been successfully tested. I won't say much about the significance of this progress to the empire. On behalf of the People's Committee of Energy and the Planning Institute, I would like to extend my warm congratulations to everyone on the front line of R&D and production."

Although everyone here knows the true connotation of the so-called "independent research and development", everyone still gave warm applause - after all, it takes good craftsmanship to make a good model with Tamiya's boards, let alone Faraday's " "Board parts" are the kind of sailboat models produced by small factories in Eastern Europe, and it is remarkable to be able to manufacture them.

After the applause, the Standing Committee member continued to say: "The successful manufacture of electric motors is only a tiny step in the process of establishing our prime mover system. At present, we have begun to use steam engines extensively. However, the use of steam engines is limited by venues, transportation, fuel supply, etc. And many other restrictions, and low security, its high energy consumption and relatively low energy density are not enough to meet our rapid development of the cause. And electricity is still indispensable in the metallurgical and chemical industries. Therefore, the promotion of electrification will inevitably affect our Our business has brought about earth-shaking changes and a rapid rise. The upper and lower members of the Senate, comrades in the Executive Committee, and colleagues in the Planning Institute are all eager to develop our electric power business as soon as possible. And the development of our electric power industry depends on you. .”

There was another burst of warm applause below.

"Next, we invite the person in charge of the power development plan: Comrade Qian Liushi to talk about our power development plan."

Qian Liushi stood up, took a folder and walked up to the podium with a happy face—he first shook hands with Chang Kaishen warmly, then motioned for the elder sitting by the bed to close the curtains, and then he opened a window on the table. projector
This is not a computer projector, but a traditional transmissive projector, and the veterans present are quite familiar with this kind of projector.For Qian Liushi, this kind of projector is the most advanced multimedia equipment he encountered in elementary school and junior high school, and he even made many slides for teachers.Nowadays, no one is in the mood to spend a long time making PPT on the computer, and they don’t have the Internet, so they can’t choose and download appropriate pictures and materials from the vast amount of information on the Internet, so they can only draw by hand—on the computer. It's better to draw it by hand directly on the plastic sheet.

And in this kind of discussion meeting, a simple schematic diagram is enough, not to mention that everyone often has an idea for a while, draw it by yourself when others are speaking, and put the schematic diagram drawn by yourself on it after the other person has finished speaking After the lecture, you can also make corrections while talking.It is really a big killer tailored for the elders.

The Planning Institute purchased [-] units before the D day. After D-Day, due to habitual problems, digital projectors were still used in other meetings, except that the Ministry of Education immediately put them into use in schools.It was not until recently that the stock of projector bulbs dropped to the warning level that these projectors were suddenly remembered.

Since most of them have been taken away by the Ministry of Education, the rest have become sweet pastries, and only a few major departments such as the Planning Institute have gotten their hands.

Qian Liushi cleared his throat and said:
"Now I will briefly explain the agenda of today's meeting based on the results of the discussions in the forum and other meetings. I also hope that you can add what I have not listed. Next, let me talk about the current situation of our Lingao Electric Power Company. "

A few days ago, Qian Liushi and Faraday had a long talk with Chang Kaishen and Wu De at the Planning Institute.The content of the conversation is mainly about the current situation of the power sector, the existing machinery manufacturing, the production capacity and technical level of the metal smelting industry.The power company is actually just an enterprise that generates, transmits and distributes power. The manufacture of power equipment actually depends on the industrial sector, and the level of machinery manufacturing and the capabilities of the metallurgical industry determine the scale and level of the power industry.

临高电力拥有的全部发电能力，目前联入电网的总发电瓦数为1120KW 其中水力发电为600KW,百仞水电站的3台200KW机组。火力发电520KW：博铺丰城轮电站100KW，博铺火电站420KW――由2台捷克制造的固定式锅驼机驱动。

In addition to this 1120KW, they also have a total of 400KW of wind power, small hydropower, solar power and thermal power that are not connected to the grid and operate in the mode of self-provided power stations.Most of them are for sporadic residents to solve the problem of domestic electricity consumption, which is meaningless to the electric power industry.Only in Sanya, there is a 1KW generator set driven by a boiler machine and a 100KW generator set driven by a diesel engine, which has been converted into a gas engine, which is used by Mali Iron and Steel Company. "

The "grid" of Lingao Electric Power -- according to Qian Liushi and other electricians, the power transmission and distribution system formed by laying 10KV transmission cables along the Wenlan River is not a "network" at all.It is just a power transmission system composed of one bus bar: there are only two outgoing lines, with several π connections in the middle, and a few small power distribution rooms.That is primitive and crude.Even so, Lingao Electric Power Company insisted from the very beginning that it should be connected to the grid for power supply.The picture shows the stability and continuous power supply capacity of the power grid.If the self-provided power station mode is adopted, once the equipment needs to be repaired, the power must be cut off. With the power grid, the maintenance of the power generation equipment will not affect the power supply.This is of great significance to many departments and enterprises that need continuous electricity consumption.

However, this "grid" was too crude at the beginning, not only did not show much superiority, but it collapsed frequently.The main problem is that the grid-connected power generation power is insufficient at the beginning.Lingao Electric Power Company has worked hard to make the grid-connected power barely exceed 1MW, which is considered to have a little grid effect, otherwise any piece of equipment failure, including a large load disconnection, will cause the "grid" to collapse.For this reason, Qian Liushi has always hoped to install two other 2KW hydroelectric generators in place - so that this original "grid" can have a more stable operating state.

The entire power system adopts the 10KV/400V power transmission and distribution standard.The user voltage is 380V for industry and 220V for civilian use—consistent with the old space-time standard.Except for the self-provided power station, all the power consumers are the organs and industrial and agricultural enterprises of the Senate distributed along the Wenlan River, and they roughly supply the two bases of Bairencheng and Bopu.The bulk of electricity consumption is the electrolysis process of the chemical industry, precision machining and electroplating of the mechanical industry.In addition, there are medical care, pharmaceuticals and schools that can be fully guaranteed.In addition, the computers in each computing center consume electricity.In contrast, the living and office electricity consumption of the veterans is the last priority of power supply - the electricity consumption is too tight.

"...Our current industrial technology is going to a higher level, especially chemical industry and metallurgy, which all depend on sufficient power supply. The installed capacity of Lingao power grid is bound to have a big development, so the next step is to increase power generation and transmission and distribution. Sufficient strength to conduct research." Qian Liushi removed the "Current Status of Electricity Production and Supply" slide and replaced it with another one.

"The main problem we are facing now is the need for breakthroughs in material science." Qian Liushi knows: generators, motors, power transmission and distribution equipment... These are not high-tech, they have a lot of materials and original models for reference, However, the manufacture of these devices is a bit weak in terms of the current material capabilities that the industry can provide.

"The first is the self-produced silicon steel sheet. The Mariao Iron and Steel Company is currently organizing people to carry out technical research. We don't have an electric arc furnace - of course, we may not be able to use electricity - we can only smelt it by fire. The results of the current experiment It’s the quality and the yield that are not satisfactory.”

This result is not surprising.Silicon steel is a high-grade special steel, which is very difficult.In the old time and space, it was made by electric arc furnace, so it is unthinkable for Ma Niu Iron and Steel Company to produce results immediately.

"...We have carried out further technical research on this problem." Ge Xinxin from the Ma Niao Central Heavy Industry Laboratory stood up. She was a beautiful woman in her late thirties, and she was wearing training uniforms like other male veterans around her. Her four-pocket dungaree overalls, her femininity is revealed only by the ponytail tied with a ribbon.Of course, if the seat is close to her, you can still smell a faint scent of perfume.

"The biggest difficulty in silicon steel smelting is the preparation of silicon powder. We are trying to solve this; however, our laboratory has also proposed another method to produce silicon, that is, to use copper or aluminum to reduce it. Which method to use depends on Look at the results of the experiment." She looked around at the elders in the meeting room who were paying attention to her, and said in a crisp voice, "But we can guarantee that if we give us another month, we will be able to overcome this difficulty."

Qian Liushi nodded: "Okay, in this case, we can think that the mass production of silicon steel has been solved." He continued, "The second is the power transmission line. We can't produce steel-cored aluminum stranded wire now, so the only option is The copper wire is bare. This involves the production of electrolytic copper-not only the wire needs electrolytic copper, but also the electric motor needs a large amount of electrolytic copper to produce. Our current power supply situation is a bit tight."

In the 21st century, China's industry needs to consume about 309 kWh of electricity to produce one ton of electrolytic copper.At Lingao's technical level, this energy consumption would probably have to be doubled.
