Get close to the heavy equipment of a big country, and feel the power of “Made in China” and the charm of “Chinese Brand”.
Nuclear power plant “central nervous system” China-made “dragon scale” shines “national business card”
As “the cradle of China’s nuclear power engineering” and the only comprehensive nuclear power research and development institution in my country, the China Nuclear Power Research and Design Institute affiliated to China National Nuclear Corporation can always bring people many reveries and surprises.
Have you heard of the “central nervous system” of a nuclear power plant? It describes the nuclear power safety level DCS system, which is an important system to ensure the safety of nuclear reactors and personnel, with high safety level, high technical difficulty and strict quality requirements.
In 2013, the Nuclear Power Institute raised funds to start the research and development of the “Dragon Scale” system. With more than half a century of experience in the nuclear industry, it took five years to complete the core technology research in 2018. The safety-level DCS “Dragon Scale” with independent intellectual property rights “The system came out. So far, the “Dragon Scale” system has achieved 100% localization in terms of software and system integration. In December 2022, the “Dragon Scale” system was successfully supplied to Unit 1 in Zhangzhou, and the Nuclear Power Institute has the supply capacity of a safety-level DCS with completely independent intellectual property rights in China. The two five-year relay spans have laid a solid foundation for the large-scale application of the “Dragon Scale” system in civil nuclear safety-level DCS projects.
The Dragon Scale is just a vivid microcosm of the technological innovation of the Nuclear Power Institute.
Over the years, the Institute of Nuclear Power has been actively committed to the research and development of nuclear power, and has successively developed independent nuclear power technologies CNP600, CNP1000, and CPR1000; successfully developed the third-generation large-scale nuclear power “Hualong One” (ACP1000) with completely independent intellectual property rights, and has become a shining ” “National business card”; successful research and development of multi-purpose modular small pressurized water reactor “Linglong One” (ACP100); breakthroughs in the research and development of fourth-generation nuclear reactors such as supercritical water-cooled reactors and supercritical carbon dioxide nuclear energy systems; Key equipment, digital instrument and control systems, independent nuclear power design software, etc. have all been self-made, which has greatly improved China’s nuclear power independent innovation capabilities… These scientific and technological achievements reflect that China, as a nuclear power power, is making great strides towards the “world First-class” solid pace and firm determination!
“China Plan” extracts the “Pearl in the Crown” of the manufacturing industry
In Deyang, Sichuan, the capital of heavy equipment, we walked into the complete gas turbine test bench of Dongfang Steam Turbine, a subsidiary of Dongfang Electric Group. The huge banner of “Building China’s Air Force Engine” is extremely eye-catching. This is the place where the complete G50 gas turbine was tested. , It is also the key to forging the independent gas turbine industry chain.
In early March of this year, my country’s first nationally produced F-class 50 MW heavy-duty gas turbine commercial demonstration unit, known as China’s “competitive engine”, was officially put into commercial operation in Qingyuan, Guangdong, filling the gap in my country’s independent gas turbine application field. In late March, the second G50 gas turbine was successfully ignited in Deyang, Sichuan, officially entering the commissioning stage of the entire unit, and the G50 gas turbine has made further progress in commercial operation.
The Deyang G50 project is one of the first batch of gas turbine innovation and development demonstration projects. Dongfang International, a subsidiary of Dongfang Electric Group, participated in the general contract, and Dongfang Steam Turbine provided the nationally produced F-class 50 MW heavy-duty gas turbine. Since then, China’s independent gas turbine industry has opened a new chapter of high-quality development, and the clean energy field has an independent and controllable full-chain “Chinese solution”.
Heavy-duty gas turbines are known as the “Pearl in the Crown” of the industrial equipment manufacturing industry. To operate safely under high temperature, high pressure, and high speed conditions, it involves aerodynamics, solid mechanics, combustion, mechanics, materials, automatic control, etc. The interdisciplinary system is extremely difficult to develop, and it is a symbol of a country’s scientific and technological level and comprehensive national strength. Because it is a strategic equipment related to national energy security, my country’s gas turbine industry chain is always facing the risk of being “stuck” by foreign countries.
Since 2009, Dongfang Electric Group has taken the lead in developing F-class 50 MW heavy-duty gas turbines with completely independent intellectual property rights in China. It has lasted for 13 years and has cooperated with nearly 300 units in the upper, middle and lower reaches of the industrial chain such as universities, equipment suppliers, and users. Carry out joint research, comprehensively overcome the whole process technology of gas turbine independent development and testing, build an independent F-class gas turbine design system, master the design method of the core components of the gas turbine and the overall performance of the whole machine, and the overall structure, and build a design with independent intellectual property rights Specifications, software and databases have achieved a breakthrough from “0” to “1”. The F-class 50-megawatt heavy-duty gas turbine has been rated as one of the “Top Ten National Heavies of Central Enterprises” twice.
