China’s future development firm wind energy, nuclear energy, clean energy, and will further advance the work of provinces and autonomous regions of the energy conservation front.

Output of wind turbines to the number of available energy resources, especially in the absence of wind the weather? This problem has plagued engineers and influence the decisions of potential users. Iran University of Science Mechanical Engineering AbolfazlAhmadi and MehdiAliEhyaei wind power has “energy” to the survey. Their research has been published in the recent publication InternationalJournalofExergy. Available energy is the energy in the thermodynamics to evaluate the quality parameters.

Wind is the oldest one of the resources of renewable energy. Rotating fan blades to capture wind energy and convert it into useful energy. Modern wind turbines to produce electricity to use this concept to drive the rest of the equipment. Wind turbines of different sizes, from small residential application a few kilowatts to more than 5MW of industrial-scale power generation.

Ahmadi and Ehyaei pointed out that the wind turbine have to compete with many other energy sources, primarily fossil fuels, as well as other renewable energy sources such as solar and biomass technologies. Therefore, the wind turbine to be cost-effective to comply with environmental benefits.

Wind turbines must be designed to meet the load requirements, and energy output at the lowest cost. In order to address this cost problem, we must optimize the performance characteristics, such as output power and wind speed or with the rotor angular velocity. Useful to analyze is to look at the system output of energy, “quality.” The researchers believe that Under normal circumstances, more than 9 meters per second wind speed was considered useful to be able to calculate the wind turbine does not matter, the initial study did not carry out historical analysis will be required for all the factors taken into account.

They have now developed a set of wind turbines to improve energy analysis, the wind kinetic energy to consider greater detail. Their approach is to provide a wind turbine run-time model of how the loss of potential energy. Then, put forward an optimized wind generator are three main parameters (intercept and and Orio rated wind speed) method so that at any given wind speed (from breeze to strong wind), the safe operation of the wind turbine within the parameters of maximize the use of energy.

They have a different wind speed in Iran, Tehran and Manjil two cities have embarked on a wind turbine generator energy analysis. Tehran average wind speed is low, while the Manjil is a windy city. Their formula can provide the optimal value of the wind turbine speed (change depending on wind speed). The results showed that the theoretical efficiency of the two regions increased by 20%, “waste” out of energy reduction of 80%.

TAIMA photoelectric booth installed in maglev wind turbine model has attracted many visitors.Previously, TAIMA lighting system developed wind-power generation obtained three patents. Lin Wenqi introduction, only R & D time on this project over five years, spent more than 1,500 yuan.If you do not based on long-term, is insist on not down. The United States is just a businessman at the entrance to the village in the Indus Alexander Wang Lin Wenqi looked a magnetic levitation wind turbine, after the signing of a purchase and sales contracts to require within 45 days will be the first batch of 250 sets of maglev wind power generators are sold to USA and Guam, the second batch of 1,400 units sold in South Korea supplier.

It is understood that magnetic levitation wind generators is used magnetic levitation technology theory, there is no mechanical friction in the motor case, by the wind effect so that fan motor rotation, with a wind starting, high-performance power generation, smooth operation and so on.

Lin Wenqi introduced TAIMA long been engaged in new energy development, design and production of sales, product sales to more than 60% overseas, including the United States, Singapore, New Zealand and Australia. This is the first time the company’s high-tech fair, and they received more than 20 provinces and cities companies to negotiate distribution rights for more than 10 foreign businessmen also have cooperation intention, came to negotiate a daily constant stream of customers. “I did not think the display of the fair so well, I really regret not show his face at the breakfast to the high pay!”

World Energy Council World Energy Congress in Montreal in 2010 in Portland, to the Executive Chairman Stephen TAIMA Photonics booth visits, with excitement, said: “This new wind generator to subvert the traditional wind power generation technology, will promote the use of the process of human wind. “

Laizhou City, completed a total of  wind turbines generating capacity 5938.868 kwh, the highest capacity high.

Town is located in the coastal areas of Laizhou earth wind generators farm wind turbines were installed 39 units, with a total installed capacity of 48.5 megawatts. Period of good wind for safe operation and protection work, struggling to minimize power outages, many wind power generation, to ensure the quality of wind power generation. Laizhou Wind Farm to break the previous run maintenance mode to protect the safety of electrical equipment and personnel under the premise of taking 24-hour reset the fan blower to reduce downtime as much as possible, so that power loss to a minimum. Winter favorable wind resources, wind farms to create the conditions for the overall operation. From November 2 to November 8, Yantai and Laizhou Dongyuan Wind  generators Power Group, 19-turbine wind farm within a week completed a total of 2.52846 million kwh electricity, the highest since the weeks of the commissioning of new generating capacity is high; November 9days to complete generating capacity of 997.26 thousand kwh, the highest daily production capacity has been high. As of the end of October, Laizhou completed a total generating capacity of wind farms 5938.868 kwh.

From Hohai University, efficient use of water resources and Engineering, National Engineering Research Center Security jointly developed by the Chinese wind turbine has been a major breakthrough in key technologies with independent intellectual property rights of 10kW vertical axis wind machines have been developed and manufactured, and sold to the European market.

China’s wind generators industry has developed rapidly, in 2008 the national total installed capacity of wind power to reach 12.2 million kilowatts, is “Eleventh Five-Year Plan” task two times. In 2009 the national total installed capacity is expected to reach 20 million kilowatts.

Statistics show that domestic wind turbines machine manufacturing enterprises with more than 70, more than other parts of the world’s total wind power equipment manufacturers.

However, the core technology and key components, the various enterprises is the introduction of route to go. Rely heavily on the introduction, the core technology and independent innovation capability deficiencies, resulting in high cost of wind power. The key to the wind turbine technology for basic research on China’s wind power development significance.

According to Water Resources and Hydropower Engineering, Hohai University, Professor Zheng Yuan, at present the large-scale wind turbines are horizontal axis wind turbine. But the horizontal axis wind turbine design technology complex, dozens of tons of weight to be installed in the cabin altitude of nearly 100 meters, the power exists yaw losses, these are the domestic causes of the higher cost of wind power.

In China, developed its own vertical axis wind machines without the need for wind, there is no yaw power loss; blade design is simple, completely self-design; cabin and gear box can be placed under the wind wheel or on the ground, maintenance costs, lower; vertical axis wind turbine noise smaller than the horizontal axis, noise pollution, reduced; In addition, laboratory studies have shown that the wind energy utilization coefficient of not less than the horizontal axis.

“Calculated and experimental results prove that the design of the spiral optimized S-type wind wheel wind than traditional S-wheel wind energy utilization of a net increase of 6%. This is in terms of S-type wind turbine is a very significant improvement.” Zheng Yuan said.

But here, some experts also said that wind power equipment manufacturing industry is relatively weak. Some developed countries, compared with foreign countries, China’s wind energy development, whether in technology, scale, level or speed of development, there is a wide gap. The low level of power generation equipment at home to become China’s wind power industry of the main obstacles.

Due to lack of long-term investment, China’s wind power equipment manufacturers to produce relatively small size, less intensive, product quality is not very stable, cost-effectiveness is also relatively low. High costs, high prices are constraining wind power technology commercialization and promote the use of the the biggest obstacle.

Business degree from a technical perspective, wind turbine life expectancies, it is difficult to ensure that technical service life of 20 years, hence the need to improve the reliability of all components. This can be through the fan system optimization design, selection of better materials and advanced controls and other measures to achieve.

Electrical equipment manufacturers the world’s power has the upper hand in Germany, Spain, the Netherlands, Denmark, the United States and other countries in the world could be utilization of wind from the original 50% to 98%, wind energy utilization coefficient of ultra-40%.

But in recent years, China’s wind power equipment and technology to improve and manufacture of rapid progress. In August of this year, Liaoning Province, Shenyang City, China Chong Wind Energy Co., Ltd. have complete independent intellectual property rights of the 20 units 1.5 MW wind turbines in Inner Mongolia recently Saihantala wind farm commissioning successful, the first group of 240 hours have passed the acceptance the successful realization of the grid. The 20 wind generators, the whole cost of wind turbines than abroad reduced by 20% to 30%, the average utilization rate of 99.64% and the fans.

Wind power generation due to unpredictable winds, making wind turbines the Internet is evolving into oscillation, when the wind power system disturbance frequency close to the inherent oscillation frequency, can cause significant power oscillation, and the oscillation amplitude as the disturbance will be the magnitude of change. Perturbation amplitude not only with the wind generator disturbance, but also with the parameters of the system itself, and therefore could be considered two-pronged approach to reduce disturbance on the power grid forced oscillation. Wind power will not only have forced oscillation system to produce, but also the transient stability of the system have an impact. Of course, this effect is small in wind power installed capacity is negligible, but when once the wind power in the system occupies a relatively large number of shares, this effect can not be ignored, otherwise the grid when a sudden change of wind power, the system There may be too large due to oscillations can not remain stable and transient loss of stability, and there the collapse of large power systems. In short, if and to network with higher share of wind power is rather weak, and the net negative impact is enormous.

Great efforts to develop wind generators as a clean energy has been wind power issue has become increasingly subject to the power of staff concerns. But the wind as an intermittent energy sources, combined with the forecast accuracy of wind energy resources can not be fully in line with the power system to the power quality requirements, to seek new ways and new thinking to resolve the impact of wind turbines on the system naturally becomes the work of a number of the power industry personnel targets. Use of static VAR compensator can quickly compensate for reactive power, wind power generation to maintain a stable power supply voltage of the access point, but can not adjust the active power output of wind farms. The use of battery energy storage system can be a better solution to this problem, and can guarantee the stability of the Internet voltage, but also can compensate for active power, the system will not be adversely affected. May choose from a battery, rectifier devices and inverter device composed of flexible AC transmission system as energy storage system.

News from the statistics department, said in the first three quarters of the Urumqi Economic and Technological Development Zone, the economic value of wind power industry 10.8 billion yuan, an increase of 132%.

Among them, Golden wind turbines science and technology in China’s wind power generating units of the total production and additional production volume in the first half of this year ranked first in the country. As China’s current wind generators equipment manufacturers, leader of a group, Goldwind Technology Co., Ltd. With independent R & D and marketing capabilities, market performance for eight consecutive years more than 100% increase.

Xinjiang Urumqi Economic and Technological Development Zone, an active extension of wind power equipment manufacturing industry chain, construction, wind turbines industrial parks, and proposed to build the “China Wind Valley” of the strategic objectives, has attracted a Ailm, Multi Tone, Xin Feng, and a group of Wind power machine supporting domestic and international famous enterprises stationed in parks, wind turbine production in the forefront among the Chinese.

Xin Feng installation is to make use of wind turbine loading and after-sales maintenance services to implement grew up supporting enterprise, Today, the company’s wind power business has been all over the country to install a number of wind power manufacturer, for 3 consecutive years to achieve over 50% growth in core business . Up to now, Xin Feng installed inside and outside the installation of various items at the provincial total installed capacity of wind turbines to reach 1.6 million kilowatts, the company cost-effective for one year a new level.

Goldwind supporting the Danish LM Xinjiang production of the first half of the company’s fan blades also achieved double-harvest production and sales. Golden Wind technology has successfully developed their own successful 1.5 MW, 2.5 MW Direct-drive permanent magnet synchronous wind turbine, 3.0 MW generating units are being developed, while still in high-capacity offshore wind turbine research and development.

China’s abundant wind energy resources and development potential. Preliminary estimates, the country’s land on the ground 10 meters altitude, the wind energy resource of about 3.226 billion kilowatts of total reserves could be the development and utilization of wind energy on land reserves are 253 million kilowatts. Including the sea, wind power generation in China can be used for a total installed capacity of wind farms of over 10 million kilowatts, equivalent to about 50 the Three Gorges power plant capacity.

2009 to 2010 domestic new wind turbines installed capacity will maintain an average annual growth of 30%

In 2007, China’s wind generators installed capacity reached 5.903 million kilowatts, when additional installed capacity of 3.304 million kilowatts, an increase of 127%, achieved three years ahead of “Eleventh Five-year” wind power installed capacity of 5 million kilowatts goals. By the end of 2008, China’s total installed capacity of wind power there is no suspense to break through 10 million kilowatts, two years in advance to reach this year, revised the “Eleventh Five-year” planning objectives.

Domestic demand is expected to wind power generator installed capacity between 2008 and 2010 to sustain rapid growth. 2008 new wind power installed capacity of 5.5 million kilowatts, up 60% from 2009 to 2010 the domestic wind power equipment market is expected to continue to maintain an average annual growth rate of 30%.

2011 to 2020, China’s wind turbines installed capacity of wind power added an average annual increase of 10%. Corresponds to the end of 2020 the total installed capacity of wind generators in China 190 million kilowatts, power generation accounts for more than 5%. In my opinion, the National Development and Reform Commission in 2020 to 100 million kilowatts of wind power generating capacity planning partial conservative, according to this plan, the total installed capacity of wind power generation accounted for (1.2 billion kilowatts) the proportion of about 8%, electricity generation accounts for only 3% compared with , far below the global level.
