en.Wedoany.com Reported - On April 23, Unit 1 of Huaneng Zhengning Power Plant successfully passed a 168-hour continuous operation test without human intervention, marking the first time that a million-kilowatt coal-fired power unit in China has achieved this milestone. This signifies an important advancement in coal-fired power units from automation to intelligence. The project is a major achievement of the national key R&D program "Key Technologies and Application Demonstration for Intelligent Coal-Fired Power Plants."Key Technologies

The project is led by China Huaneng Group and jointly implemented by Huaneng Xi'an Thermal Engineering Research Institute, along with nine organizations including Huazhong University of Science and Technology, Southeast University, and Xi'an Jiaotong University. As a core component of Huaneng's Longdong Energy Base, Zhengning Power Plant serves as the peak-shaving power source for the "Longdian to Shandong" ultra-high voltage direct current transmission project. The project team has broken through four core technologies, including hyper-converged intelligent control and multi-modal data deep mining, implemented 22 intelligent operation functions, and achieved automatic cruising and parameter adjustment within the 30% to 100% load range, as well as fully unmanned autonomous control during equipment start and stop operations. During the test, the unit's AGC performance was improved, and the one-time frequency regulation assessment met the standards.

This project has pioneered a trinity intelligent operation system of "smart cruising + intelligent control + smart monitoring," providing an intelligent solution for the construction of a new power system and accelerating the digital transformation of the traditional energy industry.
