81 meters.
In November 2015, China's largest offshore wind turbine was successfully installed in Pinghai Bay in Putian, Fujian. The wind turbine adopts Xiangdian XE128-5000 model, with a unit capacity of 5 MW, a channel diameter of 128 meters and a hub center height of 81 meters. It belongs to the 50MW offshore wind power project in Pinghaiwan, Putian, Fujian.
Principle
Convert the kinetic energy of wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy. This is wind energy production. The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to induce the generator to produce electricity.
Detailed information
The first permanent magnet offshore wind turbine10MW direct drive from China has completed factory testing in Deyang, Sichuan. Dongfang Electric Group has the first IEC design certification certificate for this unit in China. This is the first 10 MW offshore wind turbine produced by Dongfang Electric Group.
On August 21, 2019, in Deyang, China's equipment manufacturing capital, at Dongfang Electric Group Dongfang Motor Co., Ltd., the reporter saw that this wind turbine with completely intellectual property rights independent operated normally with a live load. Around 5:00 p.m., the factory test is completed and the product can be shipped out of the factory.
Compared to wind turbines of 5 MW and less, 10 MW wind turbines are “large”. On October 17, 2018, Dongfang Electric Group Wind Power Co., Ltd. obtained the IEC design certification certificate for 10MW offshore wind turbines issued by China Quality Certification Center. This certificat is a “passport” for the design and manufacture of 10 offshore wind turbines. MW offshore wind turbines.
