Chapter 422: electric power

With the spread of the rise of the Han nation in South America, the international situation is increasingly moving on a different trajectory from the original history.
The situation in South America continues to be turbulent. Some white families and European surplus people living in South America have gradually abandoned South America and chose the United States, Canada, Australia, New Zealand, South Africa and other countries as destinations for immigration.
Affected by this change, the United States, Canada, Australia, New Zealand, and even South Africa, Rhodesia and other colonies in Africa also received more white immigrants than in the same period in history.
The number of white people in the United States, Canada, Australia and other regions has increased. Western society is stronger than the historical period in the race among the world's ethnic groups. In the face of the historical changes caused by the rise of the Han Dynasty, Li Mingyuan was surprised, and also felt a kind of A sense of urgency.
As the time approaches the twentieth century, the development of science and technology will become more mature and complex, and the role that Li Mingyuan can play in it will become smaller and smaller. Therefore, in order to try to reduce the negative impact of the butterfly effect on the interests of Han, The research and development of some core technologies and weapons must be speeded up and carried forward.
"Using direct current to transport electricity consumes a lot of power and costs, and is not suitable for widespread promotion.
Although American Edison advocated the use of DC and tried various methods to expand the scope of DC power supply, it only improved the power supply situation in small and medium-sized cities. As for the power supply in big cities, Edison's improved DC power plants are still powerless.
The future of power transportation is in the form of AC power generation.
Although the local area lacks high-quality anthracite, ordinary thermal coal resources are not lacking. Jiangdong Sanzhou has rich thermal coal reserves, which can be used as raw materials for thermal power generation, and the central and northern areas of the country are rich in hydraulic resources. Construct large-scale hydropower stations in turbulent and large water level basins, and make reasonable use of local hydropower resources. "
Electric power is the source of future industrial development. Li Mingyuan has always paid great attention to the development of the local power industry.
"Firepower, hydropower, and even wind power can generate valuable electricity. When the first medium-sized hydropower station was built in 1882, because of imperfect technical reserves, only direct-current power generation could be used. The Limero Hydropower Station) has always had problems of low power generation efficiency and huge consumption during transportation.
In recent years, a large number of emerging companies have appeared in cities such as Changan, Songjiang, Huaiyang, and Xinjing, and the demand for electricity is more robust. Taking Xing'an Hydropower Station as an example, the first-generation power stations use only two or three generators Ten kilowatts, a power station with a total power generation of about one hundred kilowatts, can only meet the power needs of three or five medium-sized factories, but cannot cover the power supply task covering the entire city. "
Compared with the chemical industry, the technical level and control of the power industry are more difficult.
At the same time, Li Mingyuan, a chemical engineering professional, can give key guidance in many subdivided fields, while in the power field, it is only directional guidance. The help to power researchers is not as obvious as in the chemical field.
If you use the AC remote power supply, you need to increase the voltage to reduce the power loss in the transmission line, and then you must use a transformer to reduce the voltage before it can be sent to engineering and enterprises.
The DC transformer originally used in Hanguo had a simple structure and easy maintenance. Of course, the effect was not so ideal.
The AC transformer is relatively complicated. After the Royal Academy of Sciences put into operation the Xing'an Hydropower Station in 1882, it began to study the AC transformer. However, until 1886, the engineer from Westin House Company, Stanley, developed a high-performance After the AC transformer, the Han country developed a localized AC transformer in 1887 by drawing on Stanley's technical experience.
Han lags behind Americans in the field of AC transformers,
However, relying on some of the advantages of the prophets provided by Li Mingyuan, in the field of generating units, the Han country has made further achievements.
Early generators were driven by steam engines. In September 1883, the Royal Academy of Sciences used a newly invented mechanical turbine to replace the steam engine and directly connected to the generator. At the same time, the cloud gear and other devices were removed to solve the problems of unstable operation and severe wear of the generator set.
In May 1886, the new turbine achieved an efficiency of 75 kVA, and it was operating well in an experimental hydropower station on the banks of Parana.
Over two years after 1886, many researchers at the Royal Academy of Sciences tried to experimentally improve the turbine performance, and in July 1888 developed a second-generation turbine with a speed of 9,000 rpm and a power generation of 150 kilowatts.
Small turbines with a power of 150 kilowatts are insignificant compared to turbines with millions of kilowatts in future generations. However, in the current era, only the British, American, French, and German countries can achieve the same level of technology as the Chinese. .
It was the earliest to take the lead in AC hydropower stations. Although it was a step slower than the Americans due to technical reserves, it took five or six years for the Han country to make progress in the core area of ​​power again. Standing on the same starting line in the power sector, this means that the stalled power station construction project will usher in a new outbreak.
While working on the construction of the second generation power station, we are tackling the technical difficulties of the third and fourth generation power stations.
Li Mingyuan sat in the top position and gave the officials of the Ministry of Industry's Electric Power Department a clear goal: "Before 1900, complete the research target of 1000 kilowatt turbines, and by 1910, increase the power generation of turbines to 10,000 kilowatts."
According to the research and development progress of western countries in the field of emerging science and technology, the research and development goals set by Li Mingyuan for officials and relevant researchers of the Royal Academy of Sciences are not whimsical. After all, in the original history, western countries also completed within a similar time period. Technical problems in generating power.
"Your Majesty, the power generation project involves many fields, and the minister requested to allocate more scientific research personnel to assist the Ministry of Industry and Power's work."
Shen, the chief of the Ministry of Industry, took the task first, and then proposed the conditions.
"Higher students majoring in physics majoring in local universities and colleges will be your first choice. In the Royal Academy of Sciences, electric power-related researchers will also cooperate with you."
Li Mingyuan said kindly: "These people you use first, and then two or three months, when the power researchers hired by the government from Western countries arrive home, your task will be much less difficult."
"Your Majesty."
The head of the Ministry of Industry bowed slightly, and then asked cautiously: "There are twelve German power researchers in the Royal Academy of Sciences. Are most of the power researchers hired this time also German?"
"The Germans make up about half, and the rest are Austro-Hungarians, French and an American."
Li Mingyuan recalled the list of high-paying hires and laughed: "I remembered a person wrongly. Tesla did not naturalize in the United States. Now, strictly speaking, he should be a Serbian-Austro-Hungarian empire."
As a science man in the last life, it is impossible to have not heard of Tesla's name.
During the period from the end of the nineteenth century to the first half of the twentieth century, Tesla was arguably one of the most accomplished scientists.
Throughout his life, he built the largest AC hydropower station in the United States, and invented radio remote control technology X-Ray photography technology, radio, radar, fax machine, vacuum tube, neon tube, missile navigation and other hundreds of items. Profound technology and technology, and obtained about 1,000 patents, but these did not make him entangled, but often fell into a difficult economic situation.
As early as 1880, the Han Dynasty sent personnel to contact Tesla, but because of Western media's malicious smearing of the Han government, and Tesla himself was fascinated with the research and development of scientific research and other reasons, the persuasion operation has not made progress.
In 1880, Tesla was still a little-known man, and it was not difficult to forcibly tie him to South America by means of the Han Dynasty ~ EbookFREE.me ~, but one was forcibly tied and unwilling The cooperation Tesla did not help Han's scientific and technological research and development. Therefore, according to the instructions of the local government, the persuasion of Tesla has been carried out in a gentle manner.
In 1888, the long-term deployment of Tesla achieved its final success. Under the secret provocation and influence of the Han country, Tesla's relationship with its American counterparts was on the verge of rupture.
In February 1888, Edison bribed some government officials and brought Tesla to prison on suspicion of illegal competition.
In April 1888, Tesla Electric Company was banned. Although Tesla himself was released, he also lost all his assets in the United States.
In April, after being completely disappointed by his American counterparts, especially Edison, the original employer, Tesla, penniless and marginalized, reluctantly agreed to the invitation from the Han country and promised to engage in research work in South America.
Although the method is a bit unclear, as long as it can complete the tasks assigned by the local government, let alone secretly use small methods, it is more intense methods, and those intelligence personnel stationed in the United States will also try.
