China launched the world's largest onshore Wind Turbine

China launched 15 MW, the world's largest onshore wind turbine that will be tested over the next year to “thoroughly verify” its reliability.

Chinese companies have already installed the world's largest offshore wind turbine, as well as the largest floating offshore wind platform, and have now commissioned the world's largest onshore wind turbine.

The Sany Group, a multinational conglomerate known for its heavy machinery, announced on October 9 that a 15-megawatt wind turbine in Tongyu, China's Jilin province, had been commissioned, and would be tested next year to "thoroughly verify" its reliability. The company says the SI-270150 wind turbine is the largest onshore wind turbine in terms of single-unit capacity, and has the largest rotor diameter (270 meters) of any onshore wind turbine installed worldwide to date.

Sani said these include "self-designed glass fiber pre-quilting technology, long-distance automatic infusion technology for large and composite blades and three-dimensional design technology for trailing edge blind joint insertion, etc. that transform traditional manual manufacturing into intelligent manufacturing." . and improving lean manufacturing with digital intelligence. Recyclable polyurethane structural parts are also adopted to improve the recyclability of ultra-long blades."

The design life of the turbine is 25 to 30 years. The turbine blades are 131 meters long. The company says the SI-270150 features "a lightweight design and intelligent load reduction technology, which reduces overall load and facilitates long-distance ground transportation." The drivetrain features an integrated main shaft support system with double tapered roller bearings, or TRBs, which help ensure high load capacity and stability, according to the company.

The company says that as the length of the blade increases, “the requirements for stiffness and strength also increase, otherwise problems such as stall and classical vibration can occur, leading to increased vibration, or even blade breakage. To address these challenges, by adopting an optimized aerodynamic design with a large thickness and a blunt trailing edge, the overall absolute thickness of SANY RE's SY1310A wind turbine blades has been significantly improved."
