Recently, the 18-megawatt decentralized wind power project invested and constructed by Huaneng Northeast Branch Xianrendao Thermal Power Plant started generating electricity. This unit stands tall in the Xianrendao Economic Development Zone in Yingkou, Liaoning Province, which is surrounded by the sea on three sides and is full of wind. It has become a major local scenery.
It is understood that this unit is the world's largest wind turbine with single-unit capacity and represents the world's advanced level of wind turbine development and project operation and maintenance. The main engine weighs about 500 tons and adopts a 126-meter ultra-long flexible blade airfoil aerodynamic design. The wind wheel has a diameter of 260 meters and a sweeping area of over 53,000 square meters, equivalent to 7.5 standard football fields. At the same time, the unit integrates key core technologies such as efficient collaborative control of high-power-density power generation grid-connected systems, intelligent control of single machines and farm groups of high-power offshore wind turbines, and intelligent operation and maintenance throughout the life cycle of large offshore wind turbines based on digital twins. The localization rate of the whole machine is as high as 99%, making it the largest unit with wind turbine diameter and single machine power in the world. At full wind speed, the unit fan can generate 44 kilowatt-hours of electricity per revolution, and can output 74 million kilowatt-hours of clean electricity every year, which can meet the annual electricity demand of 40,000 households, equivalent to saving about 25,000 tons of standard coal every year., reducing carbon dioxide emissions by about 61,000 tons, which has significant energy conservation and emission reduction effects.
