At present, during the peak summer power supply period, as one of the first batch of clean and efficient supporting power projects in Jiangsu Province to be established before renovation, on July 15th, after completing 168 hours of full load trial operation, the No. 3 coal-fired power unit of the second phase expansion project of Jiangsu Changzhou Company of National Energy Group was officially put into commercial operation, 44 days ahead of schedule, providing power guarantee for regional energy supply. With the acceleration of the construction process of the new power system, the proportion of renewable energy installed capacity has significantly increased, and the role of coal-fired power in providing bottom support and peak shaving and frequency regulation has become more prominent. The previously released "Implementation Plan for the New Generation Coal fired Power Upgrade Special Action (2025-2027)" clearly states that "on the basis of implementing the 'three reforms linkage', we will promote coal fired power to better play a role in providing support and regulation in the new power system, and promote the transformation and upgrading of traditional industries through the development of the new generation of coal fired power. The No. 3 unit put into operation this time integrates the technology of 'multi-channel storage+energy storage powder storage' for the first time, solving the problem of dynamic matching between fuel supply and load demand. While improving the unit's ability to respond to grid demand, it also increases the flexibility of unit blending and combustion. ”The project team leader stated that this technology can enable coal-fired power units to respond more quickly and flexibly to changes in grid load, better play the role of regulating power sources, and ensure the safe and stable operation of the grid. At the same time, with the advancement of the construction of new power systems, coal-fired power units are generally facing difficulties such as main steam temperature and reheat steam temperature under low load conditions, sudden drops in boiler combustion efficiency, and soaring coal consumption for power supply during deep peak shaving. The No. 3 unit put into operation this time uses high-efficiency flexible heat recovery technology with millions of units for the first time, integrating intelligent switching of flue gas recirculation and auxiliary single and double row coordinated operation mode, which improves the heating capacity and economy of the unit. ”The above-mentioned person in charge stated that under ultra-low load conditions, raising the main and reheat temperatures to over 50 degrees Celsius each can solve the problem of low load and under temperature, saving more than 6 grams of coal per kilowatt hour and reducing the power consumption rate of the plant by about 2 percentage points. In addition, under the normalization of deep peak shaving in coal-fired power plants, millions of units face varying degrees of difficulties in controlling the unit during frequent start stop processes, low coordination efficiency of auxiliary equipment, and rising error rates in frequent start stop operations. The Implementation Plan specifies that efforts will be made to innovate and apply intelligent control technologies for deep peak shaving and rapid load changes in coal-fired power plants, actively integrate and apply technologies such as 5G and artificial intelligence, and improve the level of intelligent operation technology for power units. The No. 3 unit put into operation this time has achieved adaptive start stop for millions of units under all operating conditions for the first time in China, realizing comprehensive management and control of the entire process under different states, and improving the accuracy and reliability of unit state switching while reducing manual operations. ”The above-mentioned person in charge introduced that the unit has used real-time health assessment technology for the entire life cycle of the unit for the first time, realizing full "field" information monitoring of key sensitive parts, solving the problem of difficult prediction of performance degradation of key components under variable working conditions, developing auxiliary machine fault diagnosis and health status assessment modeling technology combining fault mechanism and data-driven, and building an integrated intelligent platform for fault warning, diagnosis, and health assessment. It is worth mentioning that Unit 3, which was put into operation this time, has for the first time applied the national production nuclear power iDCS control system in China, building a comprehensive safety architecture with active defense, boundary protection, and centralized supervision. It supports no less than 35 intelligent computing methods, 65 data analysis methods, and 20 mainstream machine learning algorithms, promoting the localization process of key core technologies. It is reported that after the completion and operation of the second phase project, the annual power generation of the power plant will reach 16 billion kilowatt hours. Compared with the average coal consumption of units in the thermal power industry, it can save about 15000 tons of standard coal per year and reduce carbon dioxide emissions by about 40000 tons, which is conducive to optimizing the regional energy structure and improving the ability of power supply and peak shaving.
