? On October 30, by China can the “ of group of electric machinery of wind of double wind rotor of 2.7MW serial type of group leading development surpasses lucky date ” to get offline formally. Aircrew of ” of date of “ Sai Rui breaks free from conventions, put forward serial type double wind rotor to arrange plan, the efficient ladder of second implementation wind energy second use, broke through the wind energy with long-standing industry to capture efficiency bottleneck, industry of the cable that it is wind wades a new circuit. “ surpasses lucky date ” to regard a stage as the fan of new generation, will at be in by 2022 countryside of “ of Hua Nengji Lin Tongyu revitalizes ” wind electric field and the net generates electricity.
Group of electric machinery of wind of ” of date of “ contest luck breaks wind energy to be able to pass a wind rotor to capture only the trade that use is inherent limitation, use structure of compact serial type double wind rotor, ladder of second implementation wind energy second use, breakthrough wind energy captures efficiency limit. Below same size, stand-alone cost is reduced 10% , wind energy utilization rate rises 15% , fan impeller measure is nearly one times narrower, this means the wind electric field in same area, machine digit and electricenergy production can promote 50% above considerably, abundantly saves land and energy natural resources. In the meantime, aircrew is right material, make, carry, the demand of dimension of installation, carry is lower, cost also is reduced subsequently, applied perspective is very wide.
As we have learned, before the development of large wind cable unit hundred it is support abroad software, but the research and development that foreign software supports group of electric machinery of wind of double wind rotor far from, because it is a new model, group of research and development needs to begin research from the beginning, besides the principle design of oneself of aircrew of double wind rotor, undertake designing software and the development of emulation software even. Through emulating the research and development of software, design software and crucial part, the technology of aircrew of double wind rotor still can feed back the research of group of traditional wind electric machinery, “ fills short board, forge is long board ” , solve be faced with now great strategical problem.
