Recently, Unit 5 of the second phase of the Wangting Power Plant, built by China Huadian Corporation Ltd. (CHD), was officially commissioned. It is China’s first fully domestically produced commercial 300-megawatt-class heavy-duty gas turbine project, and its commencement marks the first time the entire industrial chain for the localization of commercial gas turbines in China has been fully connected.
As the “jewel in the crown” of the equipment manufacturing industry, heavy-duty gas turbines are characterized by high-precision and cutting-edge technologies, new materials and complex processes. They are crucial for building a new energy system and safeguarding national energy security.
Located in Suzhou, East China’s Jiangsu Province, CHD’s Wangting Power Plant includes two 494-megawatt gas-steam combined cycle units, each equipped with the world’s first 500-megawatt fully hydrogen-cooled generators. Among them, Unit 5 is one of the first group of national demonstration projects for the innovative development of gas turbines.
After the commissioning of Unit 5, the project’s yearly power generation will reach 2.44 billion kilowatt-hours, meeting the annual demand of 2.3 million residents. It will save 200,000 metric tons of standard coal and reduce carbon dioxide emissions by approximately 900,000 metric tons each year.
The development of Unit 5 involved collaborative research by CHD, Shanghai Electric Group Co., Ltd., and other enterprises in the industrial chain. They successfully tackled several key technical problems, including the manufacturing of core components and the independent controllability of the system, and has achieved more than 30 innovative results to date. The project has realized independent controllability from the research, development and application of core components to the operation and maintenance of the complete unit, providing solid equipment support for building a new energy system and safeguarding national energy security.
