On May 22, the China Electric Power Planning & Design Association announced the 2022 winners of the awards for excellent survey, excellent design, excellent standard design and excellent computer software in the power industry. Among them, Shenhua Sichuan Tianming 2×1GW project won the first prize for national excellent engineering design.
The Tianming project fully followed the principle of “high safety and reliability, remarkable cost efficiency, advanced indicators, domestic benchmarking, wide load and high efficiency” in the design process. In light of the characteristics of the Sichuan power grid and through technological research and innovation, it achieved 56 excellent results from 15 aspects such as equipment selection, engineering quantity optimization, and new applications, while saving resources (including energy, land, water, and materials) and protecting the environment. In particular, the project adopted the EPC general contracting management mode with a fixed total price, placed top priority on design, and established an endogenous optimization mechanism. It optimized more than 20 individual projects such as the main plant foundation, cooling tower, and four major pipelines through the comparison of 10 projects of the same type, directly saving investment of 340 million yuan. Its experience has been used by many subsequent projects as reference, playing an exemplary role in reducing costs of thermal power projects. After the project was put into operation, the main performance indicators of its two generation units, such as boiler thermal efficiency, steam engine heat consumption, and pollutant emission concentration, all reached or exceeded the design standards and led their domestic peers.
The project, located in Jiangyou, Mianyang City, is the first single ultra-supercritical coal-fired generator set in Sichuan Province. It is an integral part of the Chengdu-Deyang-Jinyang load center. Construction of the project started on November 23, 2015, and the two generation units were put into operation at the end of October 2021. As of May 22, 2023, the two units had generated electricity of 15.6 billion kWh, creating remarkable economic benefits.
The above-mentioned awards in the power industry represent the highest level of China’s power engineering survey and design technology and quality. Winning the First Prize for Excellent Engineering Design marked a widespread recognition of the Sichuan Tianming project’s design technology in the industry, laying a solid foundation for the project to realize the goal of “winning the national quality engineering award and striving for the national excellent golden prize”.
