……
The system prompts sounded one after another, and Li Yang felt a warm current spread throughout his body, and he felt extremely comfortable!
In his mind, the structural diagrams of various electrical equipment meshed like gears, gradually forming complete systems:
In the 60s, the 200MW steam turbine generator set, which had just started, had a tall boiler and a sturdy steam turbine, making a roaring sound;
In the 70s, the mass production of 300MW "subcritical" units began, using reheat steam turbines to significantly improve power generation efficiency;
In the 80s, the 600MW "supercritical" unit, which represented the advanced level at that time, had greatly improved boiler parameters and operated at ultra-high pressure;
In the 90s, the million-kilowatt "ultra-supercritical" units introduced from abroad adopted variable-pressure operation, with an efficiency of up to 45%;
Entering the 21st century, a large number of "efficient and clean" coal-fired power generation units have been put into operation, pollutant emissions have been greatly reduced, and energy conservation and emission reduction have achieved remarkable results...
In just a few decades, thermal power technology has made rapid progress, unit parameters have been rising steadily, and the capacity of a single unit has doubled!
Li Yang sincerely admires the technological innovation and engineering wisdom contained in this!
He secretly sighed: With this knowledge, the power supply problem of the steel plant should be easily solved, right?
"The golden finger skill has been completed!" The system prompt sounded
[The host has learned the mature power generation technology at the end of the last century. The current power generation engineer level: advanced, power generation increased by 50%, energy consumption decreased by 20%!]
Li Yang was overjoyed. It seemed that the learning results this time were very good!
After closing the book, he walked out of the office with full confidence and strode towards the steelmaking workshop.
He didn't care at all about the countless doubtful and awed looks from behind him!
Arriving at the steelmaking workshop, Li Yang looked around and saw that everyone was still waiting anxiously, with pale faces, fearing that production would be delayed.
Secretary Zhang and several other leaders were also there, all with frowns on their faces, looking out from time to time, as if they were waiting for news from Li Yang.
Seeing him appear, I felt relieved and hurried to meet him:
"Xiao Li, is there any progress on the electricity issue? Everyone is counting on you!"
Li Yang smiled slightly and said calmly:
"Dear leaders, I have a solution to the power shortage! We need to build a new power plant and install high-power generators!"
"A new power plant?" Everyone was shocked and looked at each other.
You know, a power plant can't be built just by saying so. It requires equipment, technology, and funding!
Moreover, the country is in a difficult period right now, where will all that money come from?
Thinking of this, even Secretary Zhang was in a dilemma and couldn't make up his mind for a while.
But on second thought, Li Yang has always been prudent, keeps his word, and has never let anyone down.
Now that he has spoken, what is there to hesitate about?
After figuring this out, Secretary Zhang immediately made the decision:
"Xiao Li, you can do whatever you want! The power plant's affairs are now completely handed over to you! Whether it's personnel or materials, the factory will fully cooperate!"
Other leaders also nodded repeatedly, expressing their unconditional support.
Li Yang was overjoyed when he heard this, and his frown finally relaxed.
He bowed to the crowd and said in a sonorous voice:
"Thank you for your trust! I promise to build a power plant with the largest power and the most advanced technology in the shortest time! For our steelmaking business,
Provide the most solid power guarantee!
Before he finished speaking, the applause was thunderous and lasted for a long time!
Everyone was impressed by Li Yang's ambition, and hope ignited in their eyes!
With electricity, you have everything!
……
Soon, under the coordination of Li Yang and Secretary Zhang, the site of the new power plant was finalized and various procedures were being processed in full swing.
The factory selected a group of capable personnel and formed a special project team, led by Li Yang, who was fully responsible for the design and construction of the power plant.
Li Yang worked day and night, pushing forward without stopping.
Construction drawings, civil engineering budget, equipment selection... each link was carried out in an orderly manner under his command.
Of course, the most important thing is the main engine of the new power plant - the generator set.
According to Li Yang's idea, this will be a high-power steam turbine generator with a single unit capacity of up to 60 kilowatts.
It not only meets the existing electricity needs of the steel plant, but also leaves sufficient redundancy for future expansion and development.
However, with the technological conditions of the 60s, it was not easy to manufacture such a huge machine.
Steam turbines and generators alone are the most complex large-scale power devices, requiring precise processing technology and special materials, and it is not something that can be achieved overnight!
Not to mention the supporting equipment such as boilers, transformers, high-voltage switches, etc., all of which are technology-intensive, high-precision and cutting-edge products!
Li Yang is very clear about this.
When he was making a pinhole camera, he was almost stumped in the laboratory by material and processing problems!
But now, we are facing large-scale power generation equipment, which is many times more complicated than a camera!
The slightest mistake may lead to failure!
Thinking of this, Li Yang was secretly shocked and the pressure increased sharply.
But he quickly adjusted his mindset and devoted himself to his work.
"I have a system to protect me. Do you believe I can't handle a mere generator?!"
Li Yang secretly vowed in his heart that he would complete this seemingly impossible task as quickly as possible!
He opened the book "Thermal Power Plant and Power System" that he had read before and started a new round of study and research.
This time, he wanted to understand every component of the generator set thoroughly!
Then, based on the knowledge granted by the golden finger, targeted improvements and optimizations are carried out, striving to design a "unique" national heavy weapon!
In this way, Li Yang worked tirelessly on the drawings and models, watching his ideas gradually become reality:
———High-temperature and high-pressure boilers use the latest supercritical parameters, with reheat steam temperature up to 600 degrees and pressure up to 25 MPa. At the same time, specially made high-strength alloy steel pipes can withstand harsh working conditions and ensure safe and stable operation;
———The steam turbine adopts a four-cylinder and eight-exhaust layout, consisting of three cylinders of high, medium and low pressure, and is also equipped with a reheater and a moisture separator. The thermal efficiency
As high as 45% or more! The precise speed regulation system can achieve continuous regulation of wide loads and adapt to frequent fluctuations in the power grid;
———The generator is the most critical component, which determines the capacity and efficiency of the unit
Li Yang chose the most advanced steam turbine generator at that time. The stator bar adopts a hollow insulation structure and is filled with hydrogen, which greatly improves the heat dissipation capacity. The rotor adopts brushless excitation and the rotating rectifier is directly installed on the rotor shaft, eliminating the vulnerable carbon brushes and slip rings.
———The main transformer connects the generator and the high-voltage transmission line, which should reduce losses and ensure insulation. Li Yang uses an oil-filled self-cooling structure.
The oil tank is equipped with a respirator and moisture-proof device to cope with changes in temperature and humidity. The insulation material of the transformer uses the most advanced epoxy resin casting insulation at the time, which greatly improves the voltage resistance.
……
A series of advanced technologies and innovative processes make the performance parameters of this generator set far beyond the level of its contemporaries.
It is a unique "power heart" in the world. Once completed and put into operation, it will surely write a new chapter in the field of thermal power!
