В Китае построили самый большой ветрогенератор в мире

Just a couple of years ago, a wind turbine capacity of 15 megawatts (15 MW) was considered a record for offshore wind power, while the largest onshore turbines produced around 7 MW. In September 2023, the Chinese manufacturer Sani Energy unveiled a new wind turbine platform (the "919 platform"), which included an 11 MW model, the most powerful onshore turbine to date. In January of this year, Sani began producing blades, which are a record 131 meters long, designed for a 15 MW onshore wind turbine. The blades were manufactured in Inner Mongolia and designed to be durable and recyclable. This giant wind turbine was recently installed for testing in Tongyu County, Jilin Province, China. This breaks two world records: for the power of a land-based wind turbine and for the diameter of its rotor (the circle described by the blades), which is 270 meters. Sany stated that the turbine has an extended estimated service life of 25-30 years. The turbine also features a lightweight design and intelligent load-reduction technologies, which reduce the overall load and facilitate the generator's transportation over long distances. The transmission is equipped with double-row tapered roller bearings to support the main shaft, ensuring high load-bearing capacity and stability. The installation, occupying an area of ​​almost 57,000 square meters per rotation, is capable of generating up to 56 million kWh of energy annually. This amount of energy is enough to power 160,000 homes. Sany turbines maximize the potential of wind energy on the mainland. Despite their enormous size, the turbine is designed for lightness and ease of transportation. The rotor blade of the world's largest onshore wind turbine is 131 meters long. By comparison, the Cathedral of Christ the Savior in Moscow is "only" 103 meters tall. These massive blades, previously used in offshore wind turbines, are expected to set a new performance record. With its flexibility, allowing for power ratings from 12 MW to 16 MW, the turbine not only showcases superior design but also emphasizes adaptability. Capable of starting operation at wind speeds as low as 3 m/s and withstanding winds up to 25 m/s, it embodies stability and power. Turbine testing will last over a year at an experimental wind farm to thoroughly verify the reliability of its components and the entire system under real-world conditions. The launch of the new Sany wind turbine demonstrates the strengthening of Chinese companies' leadership in wind turbine manufacturing. Western competitors will face a very difficult time. As of 2023, Sany ranked fifth among China's largest wind turbine manufacturers.
