Our analysis of offshore wind power industry

Recently, the National Energy Board launched the Jiangsu Province, four offshore wind power project in the bidding, which many companies allow offshore wind power market saw the huge business opportunity. Huaneng, Guangdong Nuclear, Shenhua and other wind power power giants have purchased the tender, and local governments, the size of equipment manufacturers, are actively supporting business, also awarded by them. This is the industry¡¯s long-awaited tender, is seen as wind power industry in China started first tone gun. More room for development Although the first round of bidding, "mystery" need to wait, but offshore wind power in China wind generators has been the official "job" - the July 6, as one of the highlights of Shanghai World Expo, Shanghai East China Sea Bridge wind farm all the fans and the network power generation. The China and Asia¡¯s first large offshore wind farm, turned out to be looking into offshore wind heating of a microcosm. Now, the offshore wind power is becoming the new darling of the field of wind power in China. "China¡¯s New Energy and Industrial Development of wind energy, wind turbines development prospects in the maritime, offshore wind will be the future direction of China¡¯s wind energy and the high ground." Offshore wind power in China¡¯s present status, Chinese Wind Energy Association, commented an expert. The expert said that, compared to onshore wind, offshore wind power with wind energy resources are very stable and do not take up land resources, the advantages of minimal environmental impact. Meanwhile, China¡¯s reserves of offshore wind resources are very rich. According to the latest wind energy resource assessment, the national land can be used 300 million kilowatts of wind energy resources, coupled with offshore wind energy resources available, for a total of about 10 million kilowatts, and huge development potential. Earlier this year, according to the National Weather Service in China completed the first detailed investigation and evaluation of wind energy resources, measured 25 meters of water depth of 5 meters to the line within the coastal area, 50 meters height above sea level of about two hundred million kilowatts installed capacity. Broad prospects for offshore wind energy renewable energy quota pressures faced by the electricity giant, engaged in a fierce battle. As the east coast, especially Jiangsu and other coastal beach and offshore wind power has developed very good condition, the major power companies, "Happy Valley Circle Sea", China Power Investment, State Power, Huadian, China Guangdong Nuclear Power, Datang, China Resources Power, Jiangsu Guoxin Group, the German Solar CCE have to intervene. "Offshore wind power is currently being sought after for an important reason for the wind generator market." Operations in the flight control heavy machinery Co., Ltd. Zhao Song, Minister said, "First of all, to the southeast coast of the sea-based wind power, mostly in the domestic economy in these regions compared developed regions, demand for electricity is also great, so the electricity market is huge. Second, the offshore wind power generation capacity is relatively large, offshore wind resources, after all, richer than the land, which makes the installed capacity of offshore wind power project larger than the land-based wind power. "

With China¡¯s offshore wind power concession bidding to start, the industry that 2010 will be the development of offshore wind power in China the first year. Although the prospect of wonderful, but the offshore wind power in China is also a lot of difficulties. It seems many people in the industry, offshore wind power as a "premature infant", in the absence of "fully developed" hurry cases available, many ways a huge potential risk. Among these, the small wind turbines new technology of offshore wind power problem is one of the current problems to be solved. "Compared to onshore wind, offshore wind power very different use of the environment, which of the proposed wind power equipment, different requirements, from a technical point of view, a number of such requests to be more demanding. From another angle , in fact, a new technology is equivalent to setting the threshold. "Zhao Song said," The main features of offshore wind power installed capacity is greater and greater resistance to corrosion and other fans. "This year in June, the World Bank published a special report that the complexity of the marine environment than on wind turbines land, offshore wind power to solve any minor problems will have to pay a high price. China-made fan performance is not satisfactory and the import of design standards adopted by many fans is based on wind conditions in northern Europe developed entirely dependent on imports unrealistic unsustainable. China Energy Network HAN Xiao-ping, chief information officer, in an interview that although the present good prospects for offshore wind power development, but its difficult to develop than onshore wind power. Offshore wind onshore wind power technology behind nearly 10 years, but also the high cost of 2 to 3 times. At the same time, offshore wind power solar energy technology compared to the higher threshold in terms of power networks, accepted large capacity of wind power technology has not been a breakthrough, the interests of power-sharing and conventional conflicts unresolved. Therefore, the current construction of large-scale industry is still very difficult. Chinese Wind Energy Association, told reporters that the experts, and similar land-based wind power development, technical constraints from the start, the development of offshore wind power one of the factors. First, the offshore wind farm construction pre-work is very complex, requiring the erection of 70 meters in the sea or wind towers 100 meters, and the submarine topography and the movement, the basic situation of geological field observations. More to the point, offshore wind turbine unit capacity greater corrosion of the wind turbine and other requirements more stringent, a little flaw will cause the unit to stop. Second, the environment is another issue to face. In 2006, typhoon "Saomai" landfall, the typhoon hit the front Cangnan wind farm, leading to 28 of 20 Typhoon aircraft down on the wind farm almost a devastating blow. If the wind farm south of the typhoon as the safety of "the first killer", then in the north, on the sea ice every winter will be the greatest threat to the safety of fans. "Maintenance is also very important later, the sea is salty wind, so is very corrosive, which is offshore wind power equipment corrosion resistance raise new requirements, but also for the maintenance of late raised new requirements, so must have the appropriate solutions to solve these problems, the most important, the new equipment, the quality of the environment on more demanding.
