1、Wind Power Generation Technology Wind is very important and reserves of energy, it is safe, clean, and can provide abundant energy, stability of the stream. Now, use wind power has become the main form of wind, the worlds attention, and the fastest. Wind energy technology is a high-tech; it relates
2、more than a dozen of subjects, including meteorology,aerodynamics, structural mechanics, computer technology, electronic control technology,material science,chemistry, electrical engineering, electrical engineering, so the difficulty of a system technology may beyond the difficulty of space technolo
3、gy.First, The division of wind energy technologies: Wind energy technology is divided into large-scale wind power technology and small and medium sized wind power technology, although both are wind energy technology, working principles are the same, the two industries are completely different: speci
4、fic performance of the policy orientation is different in different markets, different applications, applied technology is different, totally belong to the same kinds of industries in the two sectors. Therefore, in China machinery industry meeting on the wind to large wind power and wind power to di
5、stinguish between small and medium treated separately. In addition, to meet different market needs, extending from the wind and solar technology has not only promoted the development of small wind power technology, but also for the small wind power opens up new markets. 1. Large-scale wind power tec
6、hnology: The technology of large-scale wind power in China still has a certain gap between international. The technology of large-scale wind power technology originated in Denmark and some other European countries, the wind power industry propelled by the government, because of the local wind resour

Our government has also started to boost the development of large-scale wind power technology, and a range of policies to guide industry development. Large-scale wind power technology are for the large-sc

Although wind power projects have been started, but more as complementary type, complete with independent intellectual property rights of large-scale wind power systems technology and core te
11、chnology few. The test environment needs to have been a large-scale wind power technology to mature. In addition, the large-scale wind power generation technology and network technology has also improved a number of issues still restrict the development of large-scale wind power technology.2. The te
12、chnology of small wind power: The technology of small wind power in China could compare with the international technology. In 1970s, the small wind power technology in China had been developed which has wind resources for a better situation, including Inner Mongolia, Xinjiang areas, the first small
13、wind power technology is widely used in power transmission project to the Township for a one of farmers and herdsmen household power supply, continuously updated as the technology improvement and development, not only alone but also with the combination of complementary optical has been widely used
14、in distributed independent power supply. These years as Chinese exports of small and medium wind steadily. Internationally, Chinas small and medium sized wind power technology and wind and solar technology have leapt to international leadership. Small wind power technology is mature and relatively s
15、mall by natural resource constraints, distributed independent power as a significant effect not only connected, but also the formation of more stable and reliable combination of optical complementary technologies scenery Moreover, technology is completely self-localization. Both from a technical or
16、price in the international arena are very competitive; with international has now started a small wind power in China brand; wall flower wall Hong has intensified. In the countrys most technical advantages and competitiveness of small and medium wind power has always been forgotten by the government
17、 and policy in a corner of reasons, in the early states has been to locate the small and medium sized wind power in Inner Mongolia, Xinjiang, farmers and herdsmen in remote areas to use and return into the agricultural class, low cost, shoddy, low-performance reliability, security, no security of la
18、nd mostly sparsely populated areas, most of the domestic market are subject to loss of reliability of large price war; in people subconsciously form a poor understanding of So get national attention and development. Domestic small wind power technology in the low wind start, low wind speed generatio
19、n, pitch moment, multiple protection, and a series of technical attention by the international market and international clientsunanimously approved, has a leading position. Moreover, the small and medium Wind power technology is ultimately distributed independent power supply to meet end-market, rat
20、her than large-scale wind power generation and network technologies to meet the domestic monopoly market, technology, update rate must be adapted to a broad and rapidly growing market.3. wind and solar technology: Wind is the integration of technical skills and the Small and Medium Wind Energy Solar
21、 Energy Technology, combines a variety of applications of new technology, and it covers many areas, the wide range of applications, technical differentiation is so great that a variety of techniques which can separate match. Wind and solar power is currently the world in the use of new energy techno
22、logy the most mature, most large-scale and industrial development of the industry, separate and individual solar wind has its drawbacks of development, but both wind and solar power complementary combined to realize the two new configuration of energy in natural resources, the technical programs of
23、integration, performance and price compared to aspects of the new energy source for the most reasonable, not only reduces the demand to meet under the same unit cost and expand the scope of application of the market, also increases the reliability of the product. In addition: solar and wind power ar

25、suppressed, photoelectric production of pollution on the environment greater than wind power, than substantial development in wind energy, this comparison contrast twist of meditation ., if people use the energy from the point of view, our goal is to meet the electricity from wind power generating c
26、apacity to measure the cost of solar energy economy than many . Wind, solar and wind power integration advantages, not only for the energy saving, emission reduction,opened up new horizons for the application of science to meet human needs, for the world to open a fourthRevolution.Second，Wind power
27、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), combining to a uni
28、t 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
29、 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 plasm

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 o
31、f the fan is kept constant power output. By regulating mode, fan from the output power curve is 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 functi
32、on 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 acc
