He saw that several of the power mouth elders who had continued to discuss the content of the meeting last night and planned to have a drink at the farm tea house were now sitting at the conference table with their backs straight and full of energy. [Read the latest chapter] I am very happy. Clearing his throat, he said: "You may already know that with the efforts of Senator Faraday, the Senate's first independently developed and produced practical motor has been successfully tested. I won't go into details about the great significance of this progress to the empire. On behalf of the People’s Committee on Energy and the Planning Institute, I would like to extend warm congratulations to everyone on the front lines of R&D and production.”
Although everyone here knows the true meaning of the so-called "independent research and development", everyone still applauded warmly - after all, it takes good craftsmanship to build a good model with Tamiya's panels, not to mention the "independent research and development" in Faraday's hands. "Board parts" are all sailboat models produced by small factories in Eastern Europe. It would be great to be able to make them.
After the applause, the Standing Committee member continued: "The successful manufacture of electric motors is only a small step in the establishment of our prime mover system. At present, we have begun to use steam engines extensively. However, the use of steam engines is limited by site, transportation, fuel supply, etc. There are many restrictions, such as low safety, high energy consumption and relatively low energy density, which are not enough to meet our rapidly developing industries. Moreover, electricity is indispensable in the metallurgical and chemical industries. Therefore, the promotion of electrification will inevitably have a positive impact on our The cause has brought about earth-shaking changes and rapid rise. The Senate, the comrades of the Executive Committee, and the colleagues of the Planning Institute all earnestly hope to develop our electric power industry as soon as possible. And the development of our electric power industry depends on you. .”
There was another round of warm applause.
"Next, we invite the person in charge of the electric power development plan: Comrade Qian Liushi to talk about our electric power development plan."
Qian Liushi stood up. Holding a folder, he walked up to the podium with a cheerful face - he first shook hands warmly with Chang Kaishen, then motioned to the elder sitting by the bed to close the curtains, and then he turned on a projector on the table.
This is not a computer projector. It is a traditional transmission projector, and the elders here are also quite familiar with this kind of projector. For Qian Liushi, this kind of projector was the most advanced multimedia equipment he encountered in elementary school and junior high school. He even helped teachers make many slideshows. Nowadays, no one has the time to spend a long time making ppts 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. They can only draw by themselves - and do it on the computer. If you want to draw it, you might as well draw it by hand directly on the plastic sheet.
And in this discussion meeting. A simple schematic diagram is enough, not to mention that everyone often comes up with an idea at once and finishes the drawing while others are speaking. After others have finished speaking, you can put the schematic diagram you drew on top and start speaking, and you can also make corrections while speaking. It is really a killer weapon tailor-made for the elders.
The Planning Institute purchased twenty units before 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 lamp stock of projectors dropped to the warning level that these projectors were suddenly remembered.
Because most of them have been taken away by the Ministry of Education. The rest became meat and potatoes. Only a few large departments such as the Planning Institute have obtained it.
Qian Liushi cleared his throat and said:
"Now I will briefly explain the agenda of today's meeting based on the results of previous discussions at the forum and other meetings. I also hope that everyone will add what I have not listed. Next, I will first talk about the current status of our Lingao Electric Power Company. "
Qian Liushi and Faraday had a long talk with Chang Kaishen and Wu De and others at the Planning Institute a few days ago. The content of the conversation was mainly about the current situation of the power sector, existing machinery manufacturing, and the production capacity and technical level of the metal smelting industry. A power company is actually just a power generation, transmission and distribution enterprise. The manufacturing 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.
The total power generation capacity owned by Lingao Electric Power is currently 1120kw, including 600kw of hydropower and three 200kw units of Bairen Hydropower Station. Thermal power generation 520kw: Bopu Fengcheng Hydropower Station 100kw, Bopu Thermal Power Station 420kw - driven by 2 fixed kettle machines made in the Czech Republic.
In addition to this 1120kw. They also own a total of 400kw of wind power, small hydropower, solar power and thermal power that are not connected to the grid and operate in self-provided power station mode. Most of them are used to solve domestic electricity problems for sporadic residents. It is of no significance to the power industry. Only in Sanya are there a 100kw generator set driven by a pot camel engine and a 150kw generator set driven by a diesel engine that has been converted to a gas engine used by Ma Niao Iron and Steel Company. "
The "grid" of Lingao Electric Power - According to Qian Liushi and other power people, the power transmission and distribution system formed by laying 10kv transmission cables along the Wenlan River cannot be said to be a "network" at all. It is just a power transmission system composed of one busbar: there are only two outgoing wires, a few π connections in the middle, and a few small power distribution rooms. That is primitive and crude. Even so, Lingao Electric Power Company has insisted on interconnected power supply from the beginning. The picture shows the stability and continuous power supply capability of the power grid. If the self-provided power station model is adopted, the power must be cut off once the equipment needs to be inspected. Since there is a power grid, the inspection of power generation equipment will not affect the power supply. This is of great significance to many departments and businesses that require continuous power consumption.
However, at the beginning, this "power grid" was too crude. Not only did it not show many advantages, it also collapsed frequently. The main problem is insufficient grid-connected power generation at the beginning. Lingao Electric Power Company has worked hard to make the power of grid-connected power generation barely exceed 1MW, which can be regarded as a little grid effect. Otherwise, any equipment failure, including a large load off-line, will cause the "grid" to collapse. For this reason, Qian Liushi has always hoped to install two other 200kw hydroelectric generators in place - so that this primitive "power grid" can operate in a more stable state.
The entire power system adopts the 10kv/400v power transmission and distribution standard. The user voltage is industrial 380v and civilian 220v - consistent with the old time and space standards. With the exception of self-provided power stations, all electricity consuming units are agencies of the Senate and industrial and agricultural enterprises distributed along the Wenlan River. The supply is roughly concentrated in the two bases of Bairencheng and Bopu. The bulk of electricity consumption is the electrolysis process in the chemical industry, precision machining and electroplating in the mechanical industry. In addition, medical, pharmaceutical and schools are also able to receive adequate electricity guarantee. In addition, the computers in each computing center use electricity. In contrast, the elders' electricity consumption for their daily lives and offices was ranked last in the power supply priority list - electricity consumption was too tight.
"...Our industrial technology is now 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, transmission and distribution. Enough effort to study." Qian Liushi took down the slide "Current Current Situation of Electricity Production and Supply" and replaced it with another.
"The main problem we are facing now is the need for breakthroughs in material science." Qian Liushi knew: generators, motors, power transmission and distribution equipment... these are not high-tech. They have enough data and original models to refer to. However, the manufacturing of these equipment is actually a bit weak based on the material capabilities that the industry can currently provide.
"The first is to produce self-produced silicon steel sheets. Ma Niao Steel Company is currently organizing people to carry out technical research. We do not have an electric arc furnace - of course, if we do, we may not be able to use electricity - we can only use fire smelting. The results of the current test It’s the quality and output that are unsatisfactory.”
This result is not surprising. Silicon steel is a high-grade special steel and is very difficult to manufacture. In the old days, electric arc furnaces were used for manufacturing, so if you want Ma Niao Iron and Steel Company to produce results immediately, you don't have to think about it.
"...We have already carried out further technical research on this issue." Ge Xinxin from Ma Niao Central Heavy Industry Laboratory stood up. She is a beautiful woman in her late thirties, wearing training uniforms like other male veterans around her. She wears a four-pocket work clothes made of coarse blue cloth, and only the ponytail tied with a ribbon reveals her feminine features. Of course, if the seat is close to her, you can 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; but our laboratory has also proposed another method to produce silicon, which is to use copper or aluminum for reduction. Which method should be used? Let’s look at the results of the test.” She looked around at the elders in the conference room who were paying attention to her, and said in a clear voice, “But we can guarantee that if you 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 transmission lines. We can't make steel-core aluminum stranded wires now, so the only option is Bare copper wires. This involves the production of electrolytic copper - not only wires require electrolytic copper, but electric motors also require a large amount of electrolytic copper to produce. Our current power supply situation is a bit tight."
In the 21st century, Chinese industry consumes approximately 309 kilowatt hours of electricity to produce one ton of electrolytic copper. Under Lingao's technical level, this energy consumption may have to be doubled. (To be continued...)
