Recently, SCIYON successfully won the bid for the world's first 630℃ secondary reheating power project 2×1000MW ultra supercritical secondary reheating National Power Demonstration project control system (DCS), further laying the SCIYON NT6000 intelligent control system of domestic DCS leading position.
The project is China Datang Group to fully implement the national "double carbon" goal, build a clean low-carbon, safe and efficient modern energy system, deepen the specific practice of clean and efficient use of coal, CCTV news focused attention.
The strong join hands to build wisdom demonstration
The Yuncheng project aims to build a comprehensive demonstration project of clean, low-carbon, safe and abundant, economically efficient, supply-demand coordination, flexible and intelligent, which will make a contribution to further speeding up the construction of a new electric power system in our country.
As the pioneer and leader of domestic DCS, SCIYON provides autonomous control, fieldbus, intelligent monitoring and other perfect control system solutions for the diversity needs of large generator sets. It has been deployed and applied in many millions of units such as Zheneng Group, Jiangsu Guosen, Guangdong Energy, Waneng Group, and continues to escort the safe and efficient operation of energy core heavy equipment.
Full range, the whole process of independent control: SCIYON for the Yuncheng national power demonstration project to provide a full range, the whole process of independent control NT6000 intelligent control system, including unit units, public systems, auxiliary control systems, matching APS automatic start and stop function, improve the unit start and stop process of the intrinsic safety, greatly reduce the work intensity of operators. The whole system conforms to the network security level protection 2.0 level three standards.
High performance intelligent power generation ICS: Based on the group's intelligent "three effects" and "three uses" as the construction principle, with the self-controllable NT6000 control system as the underlying support, with the help of advanced technologies such as artificial intelligence algorithms, mathematical modeling and expert knowledge, and through the deployment of powerful computing resources such as high-performance optimization controllers, advanced application servers and large time series databases, an integrated intelligent power generation control platform has been established. Synchronous establishment of intelligent control, intelligent monitoring and other advanced functions, significantly improve the level of production and operation, and vigorously promote the digital and intelligent construction of Yuncheng national electric power demonstration project.
Efficient and economical fieldbus: In the unit unit, public, auxiliary control and other systems are widely used fieldbus, a total of more than 3500 bus equipment in the plant, can transmit various parameters of the equipment, ensure more accurate data transmission at the same time, provide more comprehensive and rich equipment information data, reduce cable laying and construction costs, improve equipment health management ability, reduce the whole life cycle operation cost, Improve the level of automation, information and intelligence of the unit.
The 630℃ Datangyuncheng National Power Demonstration Project is located in Yuncheng County, Heze City, Shandong Province, with a total investment of 9.3 billion yuan, the construction of 2 1 million kilowatts of ultra-supercritical secondary reheating coal-fired generating units is the world's "highest pressure, highest temperature, highest efficiency, and lowest coal consumption" single-axis thermal power units of 1 million kilowatts. After putting into operation, the annual power generation can reach 11 billion KWH, saving more than 200,000 tons of standard coal and reducing 550,000 tons of carbon dioxide compared to the conventional one million reheating units. The project gathers the high-quality resources of the whole industrial chain of thermal power equipment in China, carries out scientific and technological innovation, and takes the reheat steam temperature of 630℃ and the thermal efficiency of power generation exceeding 50% as a demonstration site. The designed main steam pressure of the unit is 35.5 mpa, and the coal consumption of power generation is 245.74 grams per KWH. The use of 10 major innovative technologies, especially the first application of a new generation of martensitic heat-resistant steel G115® new material independently developed by China in power equipment, has filled the technical gap in the field of national high-temperature material research and development, and is of great significance to accelerate the process of equipment autonomy, which will drive China's thermal power equipment design, manufacturing, new materials and new processes to a new level.
As the "13th Five-Year Plan" period of the country's only one million kilowatt-level coal power demonstration project and Shandong Province's new and old kinetic energy conversion major project, the project will greatly promote the coordinated development of local economy and society, and further consolidate China's leading position in the field of coal power technology.
