【導(dǎo)讀】風(fēng)能是非常重要并儲(chǔ)量巨大的能源，它安全、清潔、充裕，能提供源源不絕，穩(wěn)定的能源。利用風(fēng)力發(fā)電已成為風(fēng)能利用的主要形式，受到世界各國的高度重視，而且發(fā)展速度最快。難度毫不遜色于航天技術(shù)。屬于完全不同的兩個(gè)行業(yè)：具體表現(xiàn)在“政策導(dǎo)向不同、市場不同、應(yīng)用領(lǐng)域不同、應(yīng)用技術(shù)更是不同，因此，在中國風(fēng)力機(jī)械行業(yè)會(huì)議上已經(jīng)把大型風(fēng)電和中小型風(fēng)電區(qū)。并出臺(tái)一系列政策引導(dǎo)產(chǎn)業(yè)發(fā)展。在風(fēng)力發(fā)電系統(tǒng)中兩個(gè)主要部件是風(fēng)力機(jī)和發(fā)電機(jī)。風(fēng)力機(jī)通過葉輪捕獲風(fēng)能，將風(fēng)能轉(zhuǎn)換為作用在輪轂上的機(jī)械轉(zhuǎn)矩。速度較定漿距風(fēng)力機(jī)低，停機(jī)時(shí)傳遞沖擊應(yīng)力相對(duì)緩和。由于變漿距調(diào)節(jié)風(fēng)力機(jī)受到的沖擊較之其它風(fēng)力機(jī)要小得多，可減少材料使用率，降低整體重量。且變距調(diào)節(jié)型風(fēng)力機(jī)在低風(fēng)速時(shí)，可使槳葉保持良好的攻角，比失速調(diào)節(jié)型風(fēng)力機(jī)有更好的能量輸出，以逐步變化到一個(gè)槳葉無負(fù)載的全翼展開模式位置，避免停機(jī)，增加風(fēng)力機(jī)發(fā)電量。
【正文】 from pulp, adjust the blade Angle of attack, the output power control in near ratings. Change from the wind plasma starting from wind speed is set slurry machine downtime at low impact stress relative ease. The normal work, is mainly adopts power control, in practical applications, power and speed is directly proportional to the set. Small changes will cause the wind changes of wind. Due to the change of wind from pulp by adjusting the impact than other wind from small, can reduce material utilization rate, reduce overall weight. And the change of wind from acmodation type at low speed, can make the blades, keep good Angle of attack than acmodation type stall wind turbines have better energy output, therefore is suitable for low average speed of the region. Change from another advantage of regulation, when the winds reach a certain value, stall type of wind and downtime, must from type machine can gradually changes to the wind load without a blades of open mode, avoid wing, increase of wind turbine. Change is to adjust the defect is sensitive response requires gusts. Because the wind acmodation type stall fan vibration power pulse are small, and acmodation type from wind turbines is bigger, especially for the change from the constant speed windmills way, this kind of circumstance, this does not require more obvious change in the fan is the response speed of wind system to fast enough, can reduce this phenomenon. 7 Third, the development of wind energy technology requires constant innovation: At present, China39。s wind energy development in technological innovation is still very weak, the lack of core technologies with independent intellectual property. Thus, much would import technology from abroad. Although the arrival of knowledge economy era, all countries take full advantage of global resources and international cooperation through the introduction of technology to bridge the gap and improve petitiveness. But if there is no capability of independent innovation, not know what the introduction of advanced technologies, are not able to absorb the future, can not carry out another record, which is on the one hand。 on the other hand, the core technology is the introduction of foreign countries cannot, and must be rely on innovation to master the core technology。 Moreover, the domestic policy of independent innovation of technology needs to supporting, guiding, supporting, with the core technology of wind energy products to be increasing support, such a wall flower wall incense situation can be change, innovation and power can e from constant innovation. In short: the wind power industry continuing to creating in a single generation from wind energy technology to power the various areas of need ,its additional products have emerged such as: street, landscape, traffic control, munication, irrigation, planting, breeding, sea water desalination , fire, alarm, islands, mountains and so on. Shows the development of wind energy in this new industry can be brought about numerous development and transformation of traditional industries, but the application of wind energy technology in various fields has bee the industry39。s benchmark. World revolution will be caused by wind energy technology from the New Energy and Industrial revolution.
