In addition, the Malta Resources will also Bahrija and HalFar two smaller land-based wind measurement activities in a similar study the possibility of land-based wind farm construction.
Pullicino said that since Malta is basically surrounded by deep-sea, surrounded by shallow reefs wind power if it proves feasible, we have to wait for deep-sea or floating wind power generation more technically mature and economically more cost-effective before considering the development of deep-sea wind power.
As the closest to commercialization of new energy – wind power equipment manufacturers and wind farm construction and operation of investment in recent years, the focus of attention. As of the end of 2009, China’s wind power installed capacity of 20 million kilowatts super-consecutive 5 years to achieve 100% growth. In 2009 the total global wind power capacity reached 157.9 GW, compared with an increase of 37.5 megawatts last year, while there are nearly one-third of new capacity from China. Is expected to the end of 2010, China’s total installed capacity of wind power is expected to reach 30 million kilowatts.
But the prosperity and development of the situation is hidden under the worry: the rapid development of wind power industry to gradually prominent issues, but in many issues, and network lag is the most prominent of all players in the focus. Inner Mongolia Ulanqab the end of 2009 appeared in the event of the plight of wind power generator outside the transmission case, which led directly to 4.3 million kilowatts of clean wind TVU area of abandoning the wind does not contribute to power generation.
“In fact, as early as this issue had been highlighted the first half of 2009. Cause of this phenomenon is the direct cause exists in the wind power industry has not broken some key technical bottlenecks, power quality and instability in the security of the entire power grid caused by potential problems. At the same time, development Wind power industry in the region is lagging behind the design and construction also contributed to the bearing pressure of weak power grid.
Installed capacity of 4.5 million kilowatts, a total investment of about 518 million Datang four grid wind power project groundbreaking ceremony held on the first phase. Datang branch in Guangxi, Guizhou provincial Energy Board and other relevant departments as well as the Liupanshui municipal party committee and other departments attended the groundbreaking ceremony.
Datang four grid wind farm is located in Guizhou Province, Liupanshui Panxian four grid rural territory, the site slopes Prairie Township is located in a four-frame ranch. The wind farm installed capacity of 100,000 kilowatts preliminary planning, with a total investment of about 10 billion yuan, sub-2 development and construction. A project plan to install stand-alone capacity of 1500 kW wind turbine group of 30 Taiwan, the annual electricity consumption of about 74.19 million kwh Internet.
Datang 4 grid wind farm construction is not only Datang Power to enter the wind power development in Guizhou marks a milestone in the market, but also energy supply, Guizhou Province, an effective supplement. From the energy efficiency and emission reduction effectiveness analysis of four grid wind farm a project is finished, and power generation compared to thermal power plants of similar size, according to coal consumption of 350 grams of standard coal power / kWh meter, the annual savings for the state standard 24.5 thousand tons of coal, relative to the current increasingly serious energy crisis, wind power has a strong vitality, in line with national industrial policies. In addition, the project could reduce emissions of sulfur dioxide 490 tons per year, carbon monoxide, 7.84 tons, 85.8 tons of nitrogen oxides, carbon dioxide, 58.8 thousand tons, 0.34 tons of hydrocarbons, ash 5880 tons, annual savings of 266,000 cubic meters of fresh water.
Ping Lu Kaidi wind power projects a total investment of 1.5 billion yuan, planning capacity of 100MW, put into operation, the estimated annual electricity output of 1.0158 billion kWh, the annual output value of 140 million yuan, paid taxes 20 million yuan. A project investment 525 million yuan, an installed capacity of 49.3MW, is now officially completed, expected in May to the grid.
Tower built in fan cylinder height of 70 meters, 28 meters long monolithic fan, has built 22 wind turbines.
Recently, China’s own R & D production of 2-megawatt permanent magnet direct-drive type of wind power converter through the identification of Wuhan, in Hubei province. This result can completely replace the imported products, some of the indicators is superior to similar foreign products.
At present, China, been able to independently produce two-megawatt permanent magnet direct-drive generator sets, but with units supporting grid converter is entirely dependent on imports, severely constrained the domestic wind power industry. In 2007, Daqo Group and the Naval Engineering Technical University, Hunan Electric shares (Quote stock bar) Co., Ltd. a joint self-developed high-power permanent-magnet direct-drive wind turbines converter. After two years of hard research has finally developed. The converter is running high-performance, power density to meet the harsh operating environment, you can type with the corresponding permanent magnet direct drive wind turbine directly supporting and providing high-quality standard-frequency power supply. Results not only to meet the future of direct-drive type wind power generation applications, the demand can also be extended to ships, aircraft and other applications.
Wind turbine in the gear box is an important mechanical parts, whose main function is to round in the wind under the action of wind generated power passed to the generator and its corresponding speed. The wind speed is usually very low round, well short of the required generator speed, gear box gear pair must pass the role of the growth achieved, it will also be called the growth in box gear box. According to the general layout of unit requirements, sometimes with the wind wheel hub directly connected to the drive shaft (commonly known as the shaft) and the gear box together as one, there will be large shaft and gear box were arranged, during installation or the use of up tight coupling connected structure. In order to increase the braking capacity of units, often in the gear box input or output is set brakes, brake with the tip (scheduled for slurry from the wind wheel) or variable pulp away from the brake transmission co-unit of the joint brake.
As the unit installed in the high mountains, wilderness, beaches, islands and other draft Department, subject to erratic changes to the role of variable load and strong gusts of wind impact on perennial withstand heat and extreme cold temperature impact, combined with the natural environment in which transportation is inconvenient and gear box mounted on top of the tower’s narrow space, the event of a failure, repair is very difficult, so its reliability and service life have raised much higher than the average mechanical demands. For example, the requirements of the component materials, in addition to regular state mechanical properties, but also should have a low-temperature state, anti-cold brittleness and other characteristics; should ensure a smooth gear box, to prevent vibration and shock; to ensure adequate lubrication, and so on. Summer and winter temperature difference of a huge area, you want to configure the appropriate heating and cooling equipment. Would also like to set up monitoring points, on the status of remote control operation and lubrication.
Different types of wind turbines are not the same as the requirements of the arrangement of the gear box and a structure and therefore vary. Horizontal axis in the wind power sector, wind turbine with a fixed parallel shaft gears and planetary gear drive the most common.
As mentioned earlier, wind power generation by natural conditions, the impact of the emergence of some special meteorological conditions, all of which might lead to failure of wind turbine, while the small cabin is not like on the ground as the machine has a solid seat base, the entire transmission system of the power matching and torsional vibration of the factors that has always epitomized the weak link in a large number of facts show that the link is often in the gear box unit. Therefore, strengthening the study of the gear box and attach importance to their work of maintenance is particularly important. Section II of the design requirements must be designed to ensure that in meeting the reliability and life expectancy under the premise of the streamlined structure and the weight of the lightest. Should normally be used CAD optimized design, optimum transmission scheduling program, select a reasonable design parameters, choose a stable and reliable components and have good mechanical properties, as well as the environment remains stable under extreme temperature variations of the material, and so on.
hina’s wind power installed capacity of 20 million kilowatts super. Is expected that the end of 2010, China’s total installed capacity of wind power is expected to reach 30 million kilowatts. The rapid development of wind power industry, the rapid expansion of wind power generator investments, local development of wind power industry, the rising enthusiasm. However, this is where the problem can not be ignored, wind power equipment to more than 70% localization rate of the cancellation of the policy will be local development of wind power industry, what impact? The development of wind power industry, local governments are faced with what issues?
For the current local wind power industry development, You Yu-feng, deputy director of the CMC that: First, the wind power market, investors increased, increasing the integration of a modern park gathering. China’s wind power manufacturing enterprises only six from 2004 to 2009, the rapid development of more than 80. But more than half of China’s wind power manufacturers and international large-scale wind power manufacturers are concentrated in several large Chinese wind power industry base. The wind power base has become a major wind power equipment manufacturing firms are concentrated area, it is thanks to its good investment environment for development, such as the abundant wind resources, it is obvious location advantages, a strong industrial base, intensive scientific and technological resources , favorable policy environment. Second, the wind turbines market investment technical risk faced by investors increasingly cautious settled location. For instance, the supply of wind power parts, there is always a certain gap, such as main bearings, gear boxes, control systems and the core components converter almost all rely on imports. Therefore, at present many potential investment in China’s wind power plant industry giants will be in selecting the site area of the development of wind power parts and components industry as an important location factor.
In the fierce international competition, China’s wind generators technology and equipment has been a lack of core technology and independent intellectual property rights for China’s wind power technology and equipment development and the development of enterprises constitutes a serious constraint to enhance self-innovation capability is to enhance the international competitiveness of the fundamental way. It is only through science and technology and human resources elements of a comprehensive integration, substantial increase in ability to innovate in order to break through resources, energy and environmental constraints. As technology advances, the trend to accelerate product upgrading, new product development and technology upgrading and other hidden costs. At the same time as the introduction of relevant national industrial policies, to increase wind turbine generator product requirements, it will also result in transformation costs. Thus, the technology has become in many wind power industry, investors need to carefully weigh the factors.
