【正文】 opened up new horizons for the application of science to meet human needs, for the world to open a fourth revolution.Second，Wind power has three kinds of operation mode:One is independent operation mode, usually a small wind generators to one or a few families to provide power, storage battery energy, to ensure the electricity without wind, Second is the wind turbines and other power mode(such as engine power),bining to a unit or an village or an island power supply, Three is wind power into conventional power operate and to provide electric power grid, is often a wind tens or hundreds of sets installed wind generators, this is the main development direction of wind power.Wind power system in the two main parts is wind machine and generators. Wind turbines to change from adjusting technique, plasma generator toward VSCF technology, this is the development trend of wind power technology is the core technology nowadays wind turbines. The following simple introduction of this two respects.1 the change of wind plasma from regulationWind turbines impeller, will capture the wind by converting wind effects on the mechanical wheel torque.Change is the change from adjustment with vertical axis wind leaf surface of Angle, thus affecting the force and the blade, when the wind resistance increases, the output power of the fan is kept constant power output. By regulating mode, fan from the output power curve smooth. In the rated wind leaf Angle of attack, controller will be placed near zero, do not change, approximate distance equal to adjust for pulp. In the rated wind above, variable structure control function 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 wind search 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.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 within dependent 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 petitiveness. But if there is no ability 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.風(fēng)力發(fā)電技術(shù)風(fēng)能是非常重要并儲量巨大的能源，它安全、清潔、充裕，能提供源源不絕，穩(wěn)定的能源。目前，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。風(fēng)能技術(shù)是一項高新技術(shù)，它涉及到氣象學(xué)、空氣動力學(xué)、結(jié)構(gòu)力學(xué)、計算機(jī)技術(shù)、電子控制技術(shù)、材料學(xué)、化學(xué)、機(jī)電工程、電氣工程、環(huán)境科學(xué)等十幾個學(xué)科和專業(yè)，因此是一項系統(tǒng)技術(shù)，其難度毫不遜色于航天技術(shù)。一、風(fēng)能技術(shù)的劃分風(fēng)能技術(shù)分為大型風(fēng)電技術(shù)和中小型風(fēng)電技術(shù)，雖然都屬于風(fēng)能技術(shù)，工作原理也相同，但是卻屬于完全不同的兩個行業(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，完全屬于同種產(chǎn)業(yè)中的兩個行業(yè)。因此，在中國風(fēng)力機(jī)械行業(yè)會議上已經(jīng)把大型風(fēng)電和中小型風(fēng)電區(qū)分出來分別對待。此外，為滿足市場不同需求，延伸出來的風(fēng)光互補技術(shù)不僅推動了中小型風(fēng)電技術(shù)的發(fā)展，還為中小型風(fēng)電開辟了新的市場。大型風(fēng)電技術(shù)我國大型風(fēng)電技術(shù)與國際還有一定差距。大型風(fēng)電技術(shù)起源于丹麥、荷蘭等一些歐洲國家，由于當(dāng)?shù)仫L(fēng)能資源豐富，風(fēng)電產(chǎn)業(yè)受到政府的助推，大型風(fēng)電技術(shù)和設(shè)備的發(fā)展在國際上遙遙領(lǐng)先。目前我國政府也開始助推大型風(fēng)電技術(shù)的發(fā)展，并出臺一系列政策引導(dǎo)產(chǎn)業(yè)發(fā)展。大型風(fēng)電技術(shù)都是為大型風(fēng)力發(fā)電機(jī)組設(shè)計的，而大型風(fēng)力發(fā)電機(jī)組應(yīng)用區(qū)域?qū)Νh(huán)境的要求十分嚴(yán)格，都是應(yīng)用在風(fēng)能資源豐富的資源有限的風(fēng)場上，常年接受各種各樣惡劣的環(huán)境考研，環(huán)境的復(fù)雜多變性，對技術(shù)的高度要求就直線上升。目前國內(nèi)大型風(fēng)電技術(shù)普遍還不成熟，大型風(fēng)電的核心技術(shù)仍然依靠國外，國家政策的引導(dǎo)使國內(nèi)的風(fēng)電項目發(fā)瘋一樣在各地上馬，各地都期望能借此分得一杯羹。名副其實的“瘋電”借著政策的東風(fēng)開始燎原之勢。雖然風(fēng)電項目紛紛上馬，但多為配套類型，完全擁有自主知識產(chǎn)權(quán)的大型風(fēng)電系統(tǒng)技術(shù)和核心技術(shù)少之又少。還需經(jīng)歷幾年環(huán)境考驗的大型風(fēng)電技術(shù)才能逐漸成熟。此外，大型風(fēng)電技術(shù)中發(fā)電并網(wǎng)的技術(shù)還在完善，一系列的問題還在制約大型風(fēng)電技術(shù)的發(fā)展。中小型風(fēng)電技術(shù)我國中小型風(fēng)電技術(shù)可以與國際相媲美。在本世紀(jì)70年代中小型風(fēng)電技術(shù)在我國風(fēng)況資源較好的內(nèi)蒙、新疆一帶就已經(jīng)得到了發(fā)展，最初中小型風(fēng)電技術(shù)被廣泛應(yīng)用在送電到鄉(xiāng)的項目中為一家一戶的農(nóng)牧民家用供電，隨著技術(shù)的更新不斷的完善與發(fā)展，不僅能單獨應(yīng)用還能與光電組合互補已被廣泛應(yīng)用于分布式獨立供電。這些年來隨著我國中小型風(fēng)電出口的穩(wěn)步提升。在國際上
