The world’s largest onshore wind turbine

Sany Renewable Energy Company of Sany Group, a multinational heavy equipment manufacturer, announced the delivery of a 15 MW wind turbine at its factory in Tongdu District, Jilin Province, China. According to the company, the machine is in prototype form and will undergo a year of testing to confirm its reliability, Interesting Engineering reported on October 10. The SI-270150 turbine model is the largest onshore wind turbine in terms of unit capacity and has the largest rotor diameter (270 m) of any onshore wind turbine installed worldwide to date. Last year, the largest wind turbine installed on land was Minyang Smart Energy’s MySE 10.X-23X with a rotor diameter of up to 230 m.

This onshore wind turbine is a flagship product manufactured based on Sany’s 12.X – 16.X MW rig. It has an operating life of 25 – 30 years. The system has a 131 m long wing, reaching a maximum scanning area of ​​57,256 m2. With such a large capacity, one turbine alone can produce enough electricity to supply 160,000 households throughout the year.

The SI-270150 has an ultra-lightweight design and artificial intelligence offloading technology, helping to minimize the load while simplifying the long-distance transportation process. These technologies increase efficiency and ensure turbines can be delivered to remote areas with fewer challenges. The turbine’s power transmission system includes a dual tapered roller bearing (TRB) with an integrated spindle support system, providing high load capacity and stability, allowing the turbine to operate more durably in a variety of conditions.

In January, Sany announced that the first wind turbine blades were produced in the Bayannur smart industrial park. As blade length increases, so does the need for greater stiffness and strength to prevent problems such as stalling, vibration and even blade breakage. To solve the problem, Sany developed an optimized aerodynamic design for wind turbine blades with large thickness and obtuse trailing edges. Such a design helps improve the structural integrity of the impeller.

Sany also incorporates a number of advanced technologies in blade manufacturing, including 3D design for trailing edge sealing and fiberglass pre-blanching technology, thereby replacing manual production with an automated process smart. To enhance the recyclability of the ultra-long blades and increase sustainability, Sany uses structural parts from recycled polyurethane.
