Chapter 336 Ultra-high Voltage Transmission Technology
The car was speeding on the road leading to the nuclear power plant, and the roar of the engine seemed to tell the urgency of the situation.
Li Yang sat in the back row, staring at the scenery passing by quickly outside the window with a serious look, and his mind had already begun to think about various possible problems.
The young staff member sitting in the co-pilot seat turned around, his face full of anxiety.
He took a deep breath and began to report the situation to Li Yang: "Engineer Li, the nuclear power plant reported that just half an hour ago, the circuit system suddenly experienced abnormal fluctuations. At first, the staff thought it was just a normal voltage fluctuation, but soon discovered that the situation was much more serious than expected."
Li Yang frowned slightly and motioned for him to continue.
The young man swallowed and continued, "According to feedback from the on-site engineers, the main transformer was severely overheated, and the transmission lines were also damaged to varying degrees.
What is most worrying is that even though they took emergency load shedding measures, the problem is still not under control."
Li Yang's brows furrowed more and more, his brain worked rapidly, quickly comparing and analyzing this information with his own knowledge.
Seeing that Li Yang didn't say anything, the young man added, "Engineer Li, they said this situation has never been seen before and they suspect there may be something wrong with the equipment itself. Now the entire nuclear power plant is on high alert. They are worried that if the problem is not solved in time, it may affect the safe operation of the reactor."
At this moment, Li Yang suddenly raised his head, a light flashed in his eyes, and the corners of his mouth slightly raised, revealing a smile of understanding.
"I understand," Li Yang's calm voice broke the tense atmosphere in the car, "The problem is not the equipment itself, but that our power transmission system cannot keep up with the power generation capacity of the nuclear power plant."
The young man and the driver both looked puzzled, obviously not fully understanding what Li Yang said.
Li Yang looked at their bewildered expressions and patiently explained: "Our nuclear power plant generators are too advanced, and the electricity they generate far exceeds the carrying capacity of the existing power transmission system. Simply put, it's like using a small water pipe to transport the water of a large river. Naturally, the water pipe can't bear it and eventually breaks."
The young man suddenly realized and exclaimed: "So that's it! Then, Mr. Li, how can we solve this problem?"
Li Yang's eyes sparkled with wisdom. He looked at the electric poles flying by outside the window, and began to think of solutions in his mind. "We need a new transmission technology, a technology that can carry ultra-large currents and ultra-high voltages." There was a hint of excitement in his voice, "We need ultra-high voltage transmission technology."
"Ultra-high voltage transmission technology?" the young man and the driver repeated in unison, obviously confused by this unfamiliar term.
Li Yang smiled and nodded, and began to explain this revolutionary technology in detail.
Ultra-high voltage transmission technology, as the name suggests, is the technology of transmitting electricity at extremely high voltage.
Compared with conventional high-voltage transmission, ultra-high voltage transmission raises the voltage to a whole new level.
In AC systems, UHV usually refers to voltage levels of 1000 kV and above; in DC systems, it refers to voltage levels of ±800 kV and above.
The core advantage of this technology is that it can significantly increase power transmission capacity and efficiency.
By boosting voltage to such high levels, UHV transmission lines are able to carry far more power than conventional high-voltage lines.
This means that with the same transmission corridor width, UHV lines can transmit up to 4-5 times the power of ordinary high-voltage lines.
Not only that, UHV transmission can also significantly reduce transmission losses.
During long-distance power transmission, electrical energy will be lost as heat due to line resistance.
Ultra-high voltage transmission can minimize this loss by increasing voltage and reducing current.
This is undoubtedly of great significance for a country like Yan, which has a vast territory and uneven distribution of electricity demand.
However, the implementation of UHV transmission technology is not easy.
It requires solving a series of technical problems such as insulation, corona effect, and electromagnetic compatibility.
At the same time, due to the extremely high transmission voltage, extremely high requirements are placed on the manufacturing process and materials of the transmission equipment.
It was because Li Yang saw the huge potential of this technology that he decided to introduce it into the power transmission system of the nuclear power plant.
After Li Yang briefly explained the basic principles of ultra-high voltage power transmission to the two people in the car, he began to conceive of a specific implementation plan.
His brain was working rapidly, like a high-speed computer, quickly matching and analyzing various technical parameters and actual situations.
"First," Li Yang said as he thought, "we need to design a complete UHV transmission system. This system mainly consists of three parts: substations, transmission lines and supporting equipment."
The young man took out his notebook and carefully recorded every word of Li Yang. Li Yang continued: "The substation is the core of the entire system. We need to design a transformer that can increase the voltage output of the nuclear power plant to 1000 kilovolts or even higher. The design and manufacture of such a super-large transformer will be a huge challenge."
Li Yang closed his eyes and the structural diagram of the transformer appeared in his mind.
He quickly calculated and adjusted in his mind, opened his eyes a few seconds later, and said, "We can use a new plug-in bushing structure, combined with an advanced cooling system, to solve the heat dissipation problem of ultra-large capacity transformers. At the same time, we also need to develop insulating materials that can withstand such high voltages."
The young man listened attentively and couldn't help but sigh: "Mr. Li, you are so thoughtful."
Li Yang smiled and continued, "The next step is the transmission line. UHV transmission lines are different from ordinary high-voltage lines. We need to design a completely new tower structure. These towers must not only be able to withstand huge mechanical stress, but also take into account the impact of the corona effect."
He thought for a moment and added: "We can use larger-section conductors, such as eight-split conductors, to increase transmission capacity and reduce line losses. In addition, we also need to design special insulator strings to ensure that flashover does not occur at such high voltages."
The driver secretly glanced at Li Yang through the rearview mirror, his eyes full of admiration.
Although he didn't quite understand the professional terms, he could feel the strong confidence and professional knowledge contained in Li Yang's words.
Li Yang seemed to be immersed in his own thoughts, and continued: "Finally, there are supporting equipment. We need to design circuit breakers, lightning arresters, transformers and other equipment that can withstand ultra-high voltage. The performance of these equipment is directly related to the safety and stability of the entire system."
He suddenly thought of something, his eyes lit up, and he said, "Oh, right, we also need to develop an advanced monitoring system. This system should be able to monitor the operating status of the line in real time, including parameters such as temperature, stress, and voltage fluctuations. Once an abnormality is found, it can be adjusted or handled immediately."
The young man was so fascinated by the speech that he almost never stopped writing. He exclaimed, "Mr. Li, you came up with such a complete solution so quickly. It's amazing!"
Li Yang smiled and shook his head, "This is just a preliminary idea. The specific implementation still requires everyone's joint efforts. However, I believe that as long as we unite as one, we will be able to overcome this difficulty."
At this moment, the car drove into the gate of the nuclear power plant. In the distance, the huge cooling tower stood in the night sky like a silent giant. Li Yang's eyes became firm, he knew that a technological revolution was about to unfold here.
The car slowly stopped, Li Yang took a deep breath, opened the door and walked out. The person who came forward was Zhang Guoqiang, the chief engineer of the nuclear power plant, his face full of anxiety and expectation.
"Engineer Li, you are finally here!" Zhang Guoqiang walked up quickly and held Li Yang's hand tightly. "The situation is getting worse and worse. We really don't know what to do."
Li Yang patted Zhang Guoqiang on the shoulder and comforted him: "Don't worry, I have thought of a solution. We will gather all the technical staff immediately. I have something important to announce."
Zhang Guoqiang was stunned for a moment, then overjoyed. He immediately turned around and told the staff around him to notify the heads of various departments. Soon, the main technical personnel of the nuclear power plant gathered in the central control room, and everyone's face was full of tension and expectation.
Li Yang stood in front of the crowd, looking at everyone with a determined look. He cleared his throat and said, "Comrades, I know that everyone is worried about the current situation. However, I want to tell you a good news: we can not only solve the current problem, but also take this opportunity to take our nuclear power plant technology to a higher level!"
Everyone looked at each other, not understanding what Li Yang meant.
Li Yang did not keep the secret and said directly: "We are going to introduce ultra-high voltage transmission technology. This technology can completely solve the transmission bottleneck problem we are currently facing, and at the same time it can greatly improve our transmission efficiency."
"Ultra-high voltage transmission?" a young engineer couldn't help asking, "Engineer Li, what is this technology? We have never heard of it."
Li Yang smiled and nodded, and began to explain in detail the principles and advantages of UHV transmission technology. As he explained, the originally confused faces were gradually replaced by surprise and excitement.
"Oh my God," exclaimed a senior engineer, "If we can really achieve this technology, it will completely change the power landscape of our country!"
Li Yang nodded and said, "Yes, this technology is far more significant than just solving our current problems. It will open up a whole new field for our country's power industry. But," he said, his voice suddenly becoming serious, "we must realize that the realization of this technology is by no means easy. We will face countless technical difficulties and challenges."
He looked around and saw determined faces. Li Yang knew that these were the country's best engineers and scientists who had the ability and determination to overcome any difficulties.
"Okay," Li Yang took a deep breath, "Now, let's get started. We will divide into several groups, each responsible for the design of the substation, transmission line and supporting equipment. Each group must have a detailed implementation plan, and we will meet every night to discuss the progress."
