Offshore wind development set-up has been sounded for development of wind power

Over the past few years, the Chinese wind power industry has been maintaining rapid development. In the development process, European companies with relatively deep accumulation of technology and experience have been regarded as the reference objects of Chinese local companies.

Since the second half of 2010, the quality of domestically produced fans has attracted much attention. However, from the perspective of the industry itself or the development path of international giants, some problems in the development process are inevitable. According to an engineer who once worked at a well-known European company, European offshore wind power has also experienced serious problems. In 2006, after a certain period of time, a 2 MW offshore wind turbine from a well-known European wind turbine manufacturer appeared. A lot of motor insulation faults, so a maintenance replacement. Such batch failures are large accidents, but they cannot be simply summarily attributed to "quality problems." From the perspective of the development of offshore wind power in Europe, similar problems are inevitable, and in the long run this will promote The key to longer-term and more stable development of the entire offshore wind power industry is to solve problems in development. It should not stop development due to minor problems that have arisen in the development process.

According to the statistical report of BTM Consulting, as of the end of 2010, the cumulative installed capacity of offshore wind power in the world was 3.554 million kilowatts, most of which were located in Europe. Among them, 1.444 million kilowatts of new offshore wind turbines were added in 2010, more than double the number in 2009, and European offshore wind power installed capacity increased by nearly 50%. It is estimated that this year will increase the installed capacity of offshore wind power by 1.4 million kilowatts. By 2015, the global installed capacity of offshore wind power will reach 26 million kilowatts.

China has a long coastline. The preliminary results of the detailed investigation of wind energy resources by the China Meteorological Administration show that China’s sea area with a depth of 5-25 meters and a height of 50 meters can have a wind power capacity of 200 million kilowatts; wind power of 5-50 meters and a height of 70 meters can be installed. The capacity is about 500 million kilowatts. China's installed capacity for offshore wind power in 2010 was the sixth largest in the world, at 106MW, accounting for 3.1% of the world's total. This is far lower than our installed capacity for onshore wind power. The UK is the largest player in offshore wind power and accounts for about half of the world's installed capacity. According to the preliminary objectives of the provinces that have been completed, offshore wind power planning in 2015 in Shanghai, Jiangsu, Zhejiang, Shandong, and Fujian will have an installed capacity of approximately 10.1 million kilowatts, of which offshore wind power is 5.9 million kilowatts and inter-tidal wind power is 4.2 million kilowatts; planning for 2020 The installed capacity is 22.8 million kilowatts, including 17.7 million kilowatts off the coast and 5.1 million kilowatts in the intertidal zone. Other provinces are set to target 5 million and 10 million kilowatts. For the future development of the wind power industry, offshore wind power will be an important growth point for the future development of the wind power industry. This has been proved by the development of the global wind power market. With the further development of offshore wind power resources and continuous improvement of technology, the offshore wind power industry will surely become the main direction for the development of the global wind power industry.

The development of offshore wind power in Europe is of reference to China, but not all experience is worthy of China's compliance. The situation on the European sea is very different from the situation in China. Europe is not cold in winter and hot in summer. Their designed survival temperature is minus 25 degrees, but this is far from enough in China. China has a lot of three types of wind speeds in the four areas. When Sinovel cooperated with Huaneng Power, the blades of the 1.5 megawatt model were generally 67 to 70 meters, and Sinovel launched 82 meters, which is more in line with China's Wind resource conditions.

Whether for Chinese companies or European companies, in the process of opening up the international market, they must be localized in terms of technology and price. For Chinese companies, only in the concept of first-aid equipment, can the industry truly develop independently. stand up.

The rapid development of offshore wind power in China in recent years has also proved this point. In 2010, 34 sets of 3MW offshore wind turbines independently developed by Huarui Wind Power Co., Ltd. were connected to all offshore wind farms except for the first offshore wind farm in Europe and the first national offshore wind demonstration project in China—Shanghai Donghai Bridge offshore wind farm. Power generation, and successful adoption of 240-hour pre-acceptance, broke the monopoly of foreign companies on high-end wind turbine manufacturing technology. Ren Haohan, chief engineer of Shanghai Donghai Wind Power Co., Ltd., stated that “As the first offshore demonstration project in China, Sinovel’s wind turbines can The average utilization rate is over 95%, and the highest is 97.7%, and the current unit operation is in good condition.At the same time, Huarui's customer service department has rich experience, meticulous maintenance, and rapid response. At the same time, after the warranty period, Huarui still has maintenance engineers resident in wind farms. Nearby, while foreign enterprise maintenance engineers can hardly do it."

Longyuan Jiangsu Rudong Tidal Interzone Experimental Wind Farm has a total of nine equipment suppliers, among which Huarui Wind Power independently researched and developed an intertidal 3 MW wind turbine with an impeller diameter of 113 meters. It is the most advanced intertidal wind turbine in the world. On September 15, 2010, it was connected to the grid. On December 13, 2010, the company passed 240 hours of assessment, and the average availability of the unit reached more than 95%. With stable operation, the availability rate will be further improved.

China’s wind power industry has just started. Compared with the long and stable development process abroad, China’s wind power can be described as rapid. Therefore, some issues that arise are relatively normal. However, with the maturity of industry technology and the stable development of the industry, the problems will be very high. Quickly solve the problem; Sinovel Wind Power, whether it is the current mainstream 1.5-megawatt land-based model or the 34-meter 3-megawatt offshore demonstration project of the East China Sea Bridge, has reached an internationally advanced level of operation. In the fast development of the wind power industry, only wind power upstream and downstream companies With joint efforts and continuous improvement of technological capabilities, we can continue to promote the long-term development of the industry and enhance the international competitiveness of China's wind power industry.
