【正文】 ut also for the small wind power opens up new markets. wind power technology: The technology of largescale wind power in China still has a certain gap between international. The technology of largescale wind power technology or desalinate in Denmark and some other European countries, the wind power industry propelled by the government, because of the local wind resourcerich, largescale wind power technology and equipment ahead of the international 36 development. Our government has also started to boost the development of largescale wind power technology, and a range of policies to guide industry development. Largescale wind power technology are for the largescale wind turbine design, wind turbine applications for large area on the very strict environmental requirements are applied to limited resources, wind energy resourcerich wind field, to accept a variety of perennial bad environment that something was the plex nature of the environment, high demands on the technology upon the line. Currently largescale wind power technology in general is not yet ripe, the core technology of largescale wind power still rely on foreign, national policy guidance to the domestic wind power project launched in various places, like crazy, all over look forward to slice. Worthy of the name madelectricity through the wind began to Negative effect and Precaution policy. Although wind power projects have been started, but more as plementary type, plete with independent intellectual property rights of largescale wind power systems technology and core technology few. The test environment needs to have been a largescale wind power technology to mature. In addition, the largescale wind power generation technology and work technology has also improved a number of issues still restrict the development of largescale wind power technology. technology of small wind power: The technology of small wind power in China could pare with the international technology. In 1970s, the small wind power technology in China had been developed develop which has wind resources for a better situation, including Inner Mongolia, Xinjiang areas, the first small 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 bination of plementary optical has been widely used in distributed independent power supply. These years as Chinese exports of small and medium wind 37 steadily. Internationally, China39。s small and medium sized wind power technology and wind and solar technology have leapt to international leader ship. Small wind power t technology is mature and relatively small by natural resource constraints, distributed independent power as a sign if i cant effect not only connected, but also the formation of more stable and reliable bination of optical plementary technologies scenery More over, technology is pletely selflocalization. Both from a technical or price in the international arena are very petitive。 with international has now started a small wind power in China brand。 wall flower wall Bong has intensified. In the country39。s most technical advantages and petitiveness of small and medium wind power has always been fotten by the government and policy in a corner of reasons, in the early states has been to locate the sma ll 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, lowperformance reliability, security, no security of land 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. Domestics mall wind power technology in he low wind start, low wind speed generation, pitch moment ,multiple protection, and a series of technical attention by the international market and international clients unanimously approved, has a leading position. Moreover, the small and medium Wind power technology is ultimately distributed independent power supply to meet end market, rather than largescale wind power generation and work technologies to meet the domestic monopoly market, technology, update rate must be adapted to a broad and rapidly growing market. and solar technology: Wind is the integration of technical skills and the Small land Medium Wind Energy Solar Energy Technology, bines a variety of applications of 38 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 technology the most mature, most largescale and industrial development of the industry, separate and individual solar w ind has its drawbacks of development, but both wind and solar power plementary bined to realize the two new configuration of energy in natural resources, the technical programs of integration, performance and price pared 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 are both new energy, solar energy than the wind started to be late more than 30 per solar PV/W by the general public about the price of recognition can be converted to a 15% rate。 while the price of small wind power conversion rationally 1/51/6 of the same 60%80%,only the low price Worse still suppressed, photoelectric production of pollution on the environment g
