He saw that several of the power mouth elders who had discussed the content of the meeting last night and wanted to have a drink at the farm teahouse were also sitting upright at the conference table in high spirits... He felt very happy. He cleared his throat and 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. I represent energy here.
The People's Committee and the Planning Institute extend warm congratulations to all those 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.
"Plate 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 passed, 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 affected 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 undertakings. Moreover, electricity is indispensable in the metallurgical and chemical industries. Therefore, the promotion of electrification will inevitably have a great impact on us.
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. The development of our electric power industry is entrusted to 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 and walked up to the podium with a folder in his hand. He first shook hands warmly with Chang Kaishen, then motioned to 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 transmission projector. The elders here are also quite familiar with this kind of projector. For Qian Liushi, this kind of projector was the first one he encountered in elementary school and junior high school.
He has the most advanced multimedia equipment, and he even helped the teacher make a lot of slides. Nowadays, no one wants to spend a long time making ppt on the computer, and they don’t have the Internet, so they can’t access the vast amount of information on the Internet.
You can choose to download appropriate pictures and materials, and you can only draw them by hand - if you draw it by hand on a computer, it is better to draw it directly on the plastic sheet.
And in this kind of discussion meeting, a simple schematic diagram is enough. Besides, everyone often has an idea at a time. When others are speaking, they draw it by themselves. After others finish speaking, they can just put the schematic diagram they drew on top of it.
Once the lecture is started, it can still be corrected 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 customary issues, except for the Ministry of Education, which immediately put them into use in schools, digital projectors were still used in other meetings. Until recently, the projector bulbs
It was only after the stock dropped to the warning level that these projectors were suddenly remembered.
Since most of them have already been taken away by the Ministry of Education, the rest have become a piece of cake, and only a few large departments such as the Planning Institute have obtained them.
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 conversation with Chang Kaishen and Wu De and others at the Planning Institute a few days ago. The conversation mainly focused on the current situation of the power sector, existing machinery manufacturing, and the production capacity and technical level of the metal smelting industry.
Question. 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. The total power generation wattage connected to the power grid is 1120kw, including 600kw hydropower and three 200kw units of Bairen Hydropower Station. Thermal power generation 520kw: Bopu Fengcheng Hydropower Station 100kw, Bopu Fire
The power station has a power capacity of 420kw - driven by 2 stationary boiler machines made in the Czech Republic.
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 self-provided power station mode. Most of them are used to solve domestic electricity problems in sporadic residents and are 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 transmission and distribution system composed of 10kv transmission cables laid along the Wenlan River is not a "network" at all. It is just a bus bar.
The power transmission system: there are only 2 outgoing wires, a few π connections in the middle, and a few small distribution rooms. It is primitive and crude. Even so, Lingao Electric Power Company has insisted on networked power supply from the beginning. This is what the picture shows
The power grid is said to have excellent stability and continuous power supply capabilities. If the self-provided power station model is adopted, the power must be cut off once the equipment needs to be inspected. Once there is a power grid, the maintenance of power generation equipment will not affect the power supply. This is very important for many departments that require continuous power supply.
It is of great significance to enterprises.
However, the "grid" was too crude at the beginning. Not only did it not show many advantages, it also collapsed frequently. The main problem was that the power generated by the grid was insufficient at the beginning. Lingao Electric Power Company tried its best to allow it to be connected to the grid and generate electricity.
The power barely exceeds 1mw, which can be regarded as a little grid effect. Otherwise, any equipment failure, including large load disconnection, will cause the "grid" to collapse. For this reason, Qian Liushi has always hoped to use the other two 200kw hydroelectric generators.
Installed in place - this will allow this original "power grid" to operate more stably.
The entire power system adopts the 10kv/400v transmission and distribution standard. The user voltage is 380v for industrial use and 220v for civilian use - consistent with the old time and space standard. All power consuming units, except self-owned power stations, are located along the Wenlan River.
Government agencies and industrial and agricultural enterprises generally supply the two bases of Bairencheng and Bopu. The majority of electricity consumption is the electrolysis process of the chemical industry, precision machining and electroplating of the mechanical industry. In addition, medical,
Pharmacies and schools. In addition, computers in various computing centers use electricity. In contrast, the seniors’ daily and office electricity consumption is ranked last in the power supply priority-electricity consumption is really 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.
Enough effort to study it." 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 materials 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 ability to manufacture these equipment is a bit weak based on the materials capabilities that the industry can currently provide.
"The first is self-produced silicon steel sheets. Ma Niao Iron and 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
The quality and output are both unsatisfactory.”
This result is not surprising. Silicon steel is a high-grade special steel and is very difficult to produce. In the old days, it was made using electric arc furnaces. If you want Ma Niao Steel Company to produce results immediately, there is no need 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, dressed in the same costume as the other male veterans around her.
She is wearing a four-pocket training uniform of coarse blue cloth. Only her ponytail tied with a ribbon reveals her feminine features. Of course, if you sit 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; but our laboratory has also proposed another method to produce silicon, that is, using 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, given 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 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 technological level, this energy consumption may have to be doubled.
