Wind energy technology is a high-tech technology that involves more than a dozen disciplines and majors such as meteorology, aerodynamics, structural mechanics, computer technology, electronic control technology, materials science, chemistry, mechanical and electrical engineering, electrical engineering, and environmental science. Therefore, It is a system technology, and its difficulty is no less than that of aerospace technology.

　　1. Division of wind energy technology:

　　Wind energy technology is divided into large-scale wind power technology and small and medium-sized wind power technology. Although both belong to wind energy technology and have the same working principle, they belong to two completely different industries: specifically reflected in different policy orientations, different markets, different application fields, and application technologies. They are even more different. They belong to two industries in the same industry. Therefore, large-scale wind power and small and medium-sized wind power have been distinguished and treated separately at the China Wind Machinery Industry Conference. In addition, in order to meet the different needs of the market, the extended wind-solar complementary technology not only promotes the development of small and medium-sized wind power technology, but also opens up new markets for small and medium-sized wind power.

　　1. Large-scale wind power technology:

　　There is still a certain gap between China's large-scale wind power technology and the international level.

　　Large-scale wind power technology originated in some European countries such as Denmark and the Netherlands. Due to the rich local wind energy resources, the wind power industry has been promoted by the government, and the development of large-scale wind power technology and equipment is far ahead in the world. At present, the Chinese government has also begun to promote the development of large-scale wind power technology and introduced a series of policies to guide industrial development. Large-scale wind power technology is designed for large-scale wind turbines, and the application areas of large-scale wind turbines have very strict environmental requirements. They are used in wind farms with limited wind energy resources and are subject to various harsh conditions all year round. Environmental postgraduate entrance examination, the complex and changeable environment, the high technical requirements have skyrocketed. At present, domestic large-scale wind power technology is generally immature, and the core technology of large-scale wind power still relies on foreign countries. The guidance of national policies has led to domestic wind power projects being launched in various places like crazy, and all regions hope to get a share of the pie. The veritable crazy power took advantage of the policies and started to spread like wildfire. Although wind power projects have been launched one after another, most of them are supporting types, and there are very few large-scale wind power system technologies and core technologies that have completely independent intellectual property rights. It will take several years for large-scale wind power technology to mature through environmental testing. In addition, the technology for power generation and grid connection in large-scale wind power technology is still improving, and a series of problems are still restricting the development of large-scale wind power technology.

　　2. Small and medium-sized wind power technology:

　　China's small and medium-sized wind power technology is comparable to the international level.

　　In the 1970s, small and medium-sized wind power technology has been developed in Inner Mongolia and Xinjiang, which have relatively good wind resources in China. Initially, small and medium-sized wind power technology was widely used in projects to transmit electricity to rural areas to provide agricultural and animal husbandry services for each household. With the continuous improvement and development of technology updates, household power supply can not only be used alone but also complement the photovoltaic combination and has been widely used in distributed independent power supply. In recent years, with the steady increase of China's small and medium-sized wind power exports. Internationally, China's small and medium-sized wind power technology and wind-solar complementary technology have leapt to a leading position in the world.

　　The maturity of small and medium-sized wind power technology is relatively limited by natural resources. As a distributed independent power generation, the effect is significant. Not only can it be connected to the grid, but it can also be combined with photovoltaics to form a more stable and reliable wind and solar complementary technology. Moreover, the technology is completely domestically produced. Both in terms of technology and price, it has very competitive advantages in the world. In addition, the Chinese brand of small and medium-sized wind power has now become famous in the world. The flowers inside the wall and the fragrance outside the wall have become more and more popular. Small and medium-sized wind power generation, which has the most technical advantages and competitiveness in China, has always been a corner forgotten by the government and policies. The reason is that in the early days, countries always positioned small and medium-sized wind power generation for use by farmers and herdsmen in remote areas such as Inner Mongolia and Xinjiang. Classified as agricultural machinery, they are low-priced, shoddily manufactured, have low performance reliability, and are not safe. Most of them are used in sparsely populated areas. Most of the domestic markets are engaged in price wars at the expense of reliability; this has formed a poor understanding in people's subconscious. , so it does not receive national attention and development.

　　At present, domestic small and medium-sized wind power technologies such as low wind speed start-up, low wind speed power generation, variable pitch, multiple protection and other technologies have attracted the attention of the international market and unanimously recognized by international customers, and have taken a leading position in the world. Moreover, small and medium-sized wind power technology is ultimately designed to meet the terminal market of distributed independent power supply, rather than the domestic monopoly market for power generation connected to the grid, as is the case with large-scale wind power technology. The update speed of technology must adapt to the broad and rapidly developing market demand.

　　3. Wind and solar complementary technology:

　　Wind-solar hybrid technology integrates small and medium-sized wind power technology and solar energy technology, and combines new technologies in various application fields. It involves so many fields, has a wide range of applications, and has great technological differentiation that cannot be compared with any single technology. of.

　　Wind energy and solar energy are currently the most technologically mature, large-scale and industrialized industries in the world in terms of new energy utilization. Wind energy alone and solar energy alone have their own development drawbacks, while wind power generation and solar power generation are complementary. The combination of the two new energy sources achieves the most reasonable comprehensive utilization of new energy in terms of allocation of natural resources, integration of technical solutions, and comparison of performance and price. It not only reduces the unit cost to meet the same demand, but also achieves the most reasonable comprehensive utilization of new energy. It also expands the scope of market applications and improves product reliability.

　　In addition: solar energy and wind energy are both new energy sources, and solar energy started much later than wind energy. The price of solar photovoltaic power generation is about 30 yuan/watt, which is recognized by the public, and the conversion rate is only about 15%; while the price of small and medium-sized wind power generation is only For the same conversion rate of 1/5-1/6, it is 60%-80%. Only this low price is even more suppressed. The environmental pollution caused by the photovoltaic production process is much greater than that of wind power, but it is lower than that of wind power. Such a contrast is thought-provoking... From the perspective of people's energy consumption, which is ultimately to meet the needs of electricity, the cost of wind energy is much more economical than solar energy when measured in terms of power generation.

　　Wind-solar hybrid integration integrates the advantages of solar and wind energy, not only opens up a new world for energy conservation and emission reduction, but also applies science to meet human needs, opening a page for the world to enter the fourth revolution.

　　2. The development of wind energy technology requires continuous innovation:

　　At present, technological innovation in China's wind energy development is still very weak, and there is a lack of core technologies with independent intellectual property rights. Therefore, technology must be imported from abroad to a large extent. Although, in the era of knowledge economy, all countries are making full use of global resources to narrow the gap and improve competitiveness through technology introduction and international cooperation. However, if you do not have the ability to innovate independently, you will not know what advanced technologies to introduce, and you will not be able to digest and absorb them after they are introduced, let alone reinnovate. This is on the one hand; on the other hand, foreign core technologies cannot be introduced, and must be Rely on independent innovation to master core technologies; furthermore, domestic independent innovation technologies need policy support, guidance, and support. Wind energy products with core technologies must increase support, so that the situation of blooming inside the wall and fragrant outside the wall can be changed. The driving force for innovation comes from continuous innovation.

　　In short: wind energy technology in the wind power industry has been constantly innovating from single power generation to various fields that require electricity, and its additional products have also emerged as the times require: street lights, landscapes, traffic monitoring, communications, irrigation, planting, breeding, seawater desalination, Fire prevention, alarm, island and mountain, etc. It can be seen that the development of wind energy, an emerging industry, can drive the development and transformation of countless traditional industries, and the application technology of wind energy in various fields has become the benchmark for the development of these industries. The world revolution that is about to be triggered will definitely come from the revolution in new energy industries such as wind energy technology.
