As wind power generation originates from Denmark, Danish wind power technology is still world-class. Whether it is winter, spring or autumn, the temperature in the wind field is very low and the climate is relatively harsh. The reason why wind power generation blades have advantages under low temperature conditions is generally that the blades have strong anti-dust and anti-freeze capabilities (the aerodynamic performance of the blades is reduced after freezing and the torque of the blades is reduced). three blades change). To prevent freezing, the first step is to choose a suitable topcoat; the second step consists of adding a hot air circulation system inside the blades.
How many meters are the blades of a large wind turbine?
The Breeze Power project is real. Zibo News Network (Reporter Wang Qi) In terms of wind power generation, Zibo has madea new breakthrough at the “Breeze Power Generation” project promotion conference and occupies a leading position. The “power cycle feedback trigger acceleration technology” used in the “Breeze Power Generation” project of Dongsheng Rongju Breeze Power Generation Co., Ltd. relies on the unique design of the wind energy harvesting structure system to fully exploit the wind energy of the breeze, causing a circulation vortex to form in the local wind field, and the wind energy enters into the wind harvesting system. Then, it can be fully utilized by circulation in the blade space. After testing, after applying this technology, the use of wind energy. The rate increased by 30% compared to before use. This is a major technological advancement in wind power generation, doubling the efficiency of electricity production.tee in the same wind conditions.
The length can reach 108 meters, 111 meters or even 115 meters.
The record for the longest wind turbine blade has been broken several times. Indeed, the length of the blades of a wind turbine depends on the rated power of the entire unit and the conditions of the wind field.
For example, for a 2 MW wind turbine, the blade length range is 48 to 59 meters; for a 3 MW wind turbine, the blade length range is 44 to 59 meters for wind turbines of 5 MW and above; The blade length range is 62 to 75 meters. This data may change with technological advancements and market demand.
For example, Mingyang Intelligent announced the development of MySE16.0 to 242 offshore models, with a single machine power of up to 16 megawatts and a planned blade length of 118 meters. China Shipping also announced the development of an offshore wind turbinee 16 megawatts, whose blade length should exceed 125 meters. All this shows that wind blades are multiplying rapidly and that the era of “large” blades has arrived.
