Beijing, June 30 (xinhua) -- China's wind-power equipment manufacturers are developing large offshore wind turbines to boost the prospects for offshore wind power.
Wednesday afternoon, the xinjiang goldwind science and technology co., LTD will be held in Beijing in the media communication, announced that the company first 6 mw direct-drive permanent magnet offshore wind turbine prototype will be connected to the grid during the first half of next year, 2014.
Cui xinwei, chief engineer of jinfeng science and technology, said: "it will be the development trend of offshore wind turbines. By increasing the capacity of single machine, we can increase the cost of the unit in the construction of wind farm and effectively reduce the total construction cost of offshore wind farm. However, the same volume of offshore wind farm construction investment is about 40% higher than onshore wind farms.
Recently, guodian united power technology co., LTD., Shanghai electric, the Chinese heavy industry (chongqing) sea wind power equipment co., LTD., and other enterprises have said, will be offline this year or early next year for 5 mw and 6 mw wind turbines on the sea. Last October, sinovel, China's largest wind turbine maker, and xiangdian wind power co., respectively, independently developed 5 mw offshore turbines.
Industry experts believe that China's wind power equipment manufacturing enterprises so densely launched large capacity fan, marks the Chinese from 3 mw offshore wind already entered 5 mw and 6 mw of transition. Experts point out that offshore wind must be able to be profitable only after a certain size of the unit's capacity and wind power.
Liu qi, deputy director of the national energy administration, said that in the future, the capacity of the future offshore single machine should be gradually developed from over 3 megawatts to over 5 megawatts, and the single-machine capacity of the intertidal project should be no less than 2 megawatts.
Offshore wind power has the characteristics of rich resources, high utilization of power generation, non-occupation of land and suitable for large-scale development. China's offshore wind energy resources are abundant, and it has been initially evaluated about 200 million kilowatts of wind resources in the shallow waters of China's offshore waters.
Vice President of the Chinese renewable energy institute wind professional committee of peng-fei shi believes that compared with onshore wind high-speed development, China's offshore wind is still in its beginning and exploring stage, China's offshore wind technology is relatively weak.
In terms of the construction of offshore wind power, China has completed the construction of offshore wind power project 13. It accounts for less than 1 percent of the total installed capacity of wind power in China and about 4 percent of the world's offshore wind power installations. There are 258 projects that have been included in the national macro vision. 80,000 kilowatts.
Liu qi said that during the 12th five-year plan period, China will promote the development of offshore wind power in a "prudent and positive" way, while "development of scale and advanced technology" is one of the principles of offshore wind power work in China. According to the national energy administration, China's offshore wind power development aims to reach 5 gw by 2015 and 30 gw by 2020. In the second half of this year, the national energy administration will launch the second batch of tender preparations for the offshore wind concession project, which is expected to be completed in the first half of next year, with a total construction scale of 1.5 million to 2 million kw.
