CTOnews.com November 3 news, from Huaneng Group officials learned that the world's first 2.7MW efficient and compact tandem twin-turbine wind turbine Huaneng "Seri" officially offline on October 30.

"Sailui", developed by China Huaneng Group Clean Energy Technology Research Institute Co., Ltd., has for the first time broken through the technical problems of coordinated energy capture and efficient cascade utilization of multi-stage impellers of wind turbine. it solves the bottlenecks such as low wind energy capture efficiency and large blade size that restrict wind turbines for a long time.

▲ Seri | Source: compared with traditional wind turbines, the efficiency of double wind turbines can be increased by 15%, the size of fan impellers is nearly doubled, and the cost is reduced by more than 10%. Under rated power, the equivalent wind energy capture power per unit sweep area is increased to about 2 times that of conventional wind turbines, which means that the number of seats and the whole field benefit can be greatly increased by more than 50% in the same area of wind farms. Greatly save land and energy resources. At the same time, the unit has lower requirements for materials, manufacturing, transportation, installation, operation and maintenance, and the cost is also reduced.

CTOnews.com learned that "Seri", as the world's first new-generation wind turbine, will be connected to the grid at the "Rural Revitalization" wind farm in Tongyu, Huaneng Jilin Province at the end of 2022.
