The ultra-high speed development of wind power is a highlight in the development of renewable energy in China during the “Eleventh Five-Year Plan†period. With the increasing tightness of land-based wind power resources and long-distance transmission problems, offshore wind power development has gradually become the focus of attention in the industry. However, Yi Yuechun, deputy chief engineer of the Hydropower and Water Conservancy Planning and Design Institute, believes that onshore wind power will be the focus of China's future development due to the quality of offshore wind turbines and the use of sea areas.
By the end of 2010, the cumulative installed capacity of wind power in China reached 44.73 million kilowatts, which surpassed the United States in ranking first in the world. The newly installed capacity was 18.93 million kilowatts, maintaining the world's top ranking. Yi Yuechun believes that the development prospects of offshore wind power in China are very impressive. This includes the attention of the state: On the basis of the issuance of the "Interim Measures for the Administration of Offshore Wind Power Development and Construction" in 2010, related departments will announce more detailed implementation details in the near future.
China’s offshore wind resources are also relatively abundant: According to the preliminary results of the China Meteorological Administration’s detailed investigation, in China's seas with water depths of 5 to 25 meters, the installed capacity of wind power at 50 meters is about 200 million kilowatts, water depth of 5 to 50 meters, and 70 meters The installed capacity of high wind power is about 500 million kilowatts. Compared with onshore wind power, offshore wind power is close to the traditional power load center, which facilitates power grid consumption and eliminates the trouble of long-distance power transmission. This is particularly tempting when the current "Three North" (northwest, northeast and north) areas suffer from "electrical power". Yi Yuechun pointed out that in a number of favorable conditions, China's offshore wind power capacity in 2015 is expected to reach 5 million kilowatts, and it is expected to reach 30 million kilowatts by 2020.
Although the outlook for offshore wind power is excellent, the reality is much more difficult. First of all, the quality of offshore wind turbines has caused confusion. In recent years, China's wind turbine manufacturing industry to achieve? “Leap forward developmentâ€, a group of companies such as Sinovel and Goldwind have been listed on the market and ranked top in the world. However, the hidden dangers caused by too rapid advancement have begun to appear frequently, and some land-based wind turbines have repeatedly appeared off the net. Accidents such as collapse and collapse have cast a shadow on the development of the industry.According to the current situation, there are no particularly satisfactory offshore wind turbines. Even the products made by Huarui, the boss of domestically produced wind turbines, have experienced replacement parts during actual operations. To this end, Longyuan Power uses 16 test units from 8 manufacturers in its operation in the Jiangsu Rudong Intertidal Wind Farm, which is expected to find the most suitable model. In addition, the contradiction in the use of sea areas is also a major constraint. Shi Pengfei, deputy director of the Wind Energy Professional Committee of the China Renewable Energy Society, told reporters that the offshore sea area is different from the northwestern Gobi desert and that many factors such as military, cable, shipping, and beach cofferdams must be considered in the process of use. .
Yi Yuechun introduced that at present, China's offshore wind power development plan is to focus on building bases in Jiangsu and Shandong, and to promote offshore wind power construction in Hebei, Shanghai and Zhejiang. This emphasis on the eyes of people in the industry makes sense. In the southeast coastal provinces such as Zhejiang and Chongqing, the typhoon is very destructive and the existing offshore wind turbines are not sufficient to withstand this risk.
Therefore, onshore wind power will still be the focus of China's future development. Although the high-speed wind-rich areas in the “Three North†zone are almost completely mined, the vast southerly inland low-wind speed zone has little potential. The future development of wind power will shift from a large-scale base construction to a combination of large-scale base construction and decentralized development.
