Recently, go up in sea of big abundant of 3 gorge Jiangsu in wind cable project, full shipment of group of electric machinery of GW184-6.45MW maritime wind goes. This aircrew carries 90 meters of lamina, it is at present home already sent the maritime wind-force generation set with big diameter of the impeller in motion unit.
Mouth of our country the Yangtse River with region of the North sea, suffer a typhoon the impact is little, among them Jiangsu is major maritime space, year average wind speed makes an appointment with 7.0m/s~8.0m/s; The area of annulus Bohai Sea such as Shandong, Heibei, Liaoning, year average wind speed makes an appointment with 6.5m/s~7.5m/s. The maritime wind report according to each local government plans, the program capacity of this area exceeds 25% of total capacity of program of maritime wind report. Aircrew of GW184-6.45MW of golden wind science and technology, for our country maritime space of afore-mentioned low wind speed measure a body custom-built, the ” of “ new sharp weapon of the contest price period that makes special needle be made to the area such as Shandong, Heibei, Liaoning. Specific for, this type has the following and main characteristic: Asia-Pacific area casts diameter of carry large vane wheel, generating capacity is stronger
Length of GW184-6.45MW aircrew lamina is 90 meters, use rise the HQ wing section that block compares, have load small, generate electricity the characteristic with tall efficiency, can reduce cost per kilowatt hour of the electricity generated by WECS, raise yield; And check through complete wind tunnel, obtain data of realer performance of wing section pneumatic, safeguard later period generates electricity reliably function. Blade in international TUV-nord of famous attestation orgnaization begins blade design and type attestation, at present blade has obtained design attestation. Blade supplier connects respect of limited company of Jiangsu of equipment of flying wind phone to express again, blade uses the advanced wing section with pneumatic superior performance, when encountering fresh gale, can reduce load through adjusting blade angle, improve pneumatic efficiency, be helpful for prolonging blade service life; Data of high-powered carbon fiber is used on the structure, reduce blade weight effectively, make product more accord with maritime fan “ light the trend that quantifies ” . Leave of 90 meters of lamina sends past project spot
Home second use damper to fall carry, reduce weight of the structure that prop up effectively
Mast damper falls to reach dependability to promote a respect to have important sense originally in aircrew, the action —— that restraining resonance respect to have 39 batches of hoisting jack especially a small quality system draws the oscillatory energy with tremendous mast, repass damp device will be oscillatory energy dissipation, achieve mast to reach overall decrease brace up, fall the end that hold, can reduce mast and fundamental weight considerably from this 10% above, raise the competition ability of aircrew and dependability thereby. Aircrew is in open of resonance rotate speed (gules) and shut (blue) damper (TMD) curve of acceleration of cat head vibration
Mark matchs lidar to promote set stability and get used to ability
Golden wind science and technology measures advanced laser hearsay feeling technology and intelligent fan to dominate technical photograph union, be equivalent to be fan mount a mind which perceives both past and future ” of “ cerebra ” and “ . Fan can feel aircrew accurately to shed wind speed, wind direction and onflow intensity to wait ahead of schedule shed an information to reach its to change, reduce aircrew load considerably thereby, optimize electricenergy production effectively, promotion aircrew is in badly the stability below wind condition and get used to ability, promote aircrew security then. The make a present of before EFarm controls sketch map
Mast headroom monitors safeguard aircrew safety to move
Mast headroom supervisory system collects aircrew to run a picture in real time through high-definition camera, deepness of use computer vision learns algorithm, processor set runs a picture, computation gives the headroom of aircrew to be apart from. The intelligence that is based on monitoring of real time headroom to realize aircrew falls carry, relax thereby of blade flexible the parameter requirement such as index, ensure the moving safety of aircrew, reduce aircrew load and blade cost at the same time. 
The par times that is full of good luck and challenge is coming, golden wind science and technology will undertake the technology innovates continuously, maritime project reduces low wind speed of the north that help strength smooth change cost per kilowatt hour of the electricity generated by WECS definitely (LCOE) , make the wind report tomorrow that high quality develops jointly with colleague of industry all circles.
