No one can guarantee that there is no fault.
In recent years, China's wind power industry has maintained rapid development. In the process of development, European companies with relatively deep accumulation of technology and experience are often used as reference targets for local Chinese companies.
Since the second half of 2010, the quality of domestically produced wind turbines has received much attention. However, no matter from the industry itself or from the development path of international giants, some problems in the development process are inevitable.
According to an engineer who worked in a well-known European manufacturer, there are also serious problems in offshore wind power in Europe. In 2006, after a period of operation of a 2 MW offshore wind turbine of a well-known European wind turbine manufacturer, a number of motor insulation faults occurred, so repairs were replaced. Such batch failures are a big accident, and the manufacturer is almost bankrupt.
However, it cannot be simply and rudely attributed to “quality problems†due to the failure of the wind turbine, and even leads to the conclusion that “products are unreliableâ€. From the perspective of the development of offshore wind power in Europe, similar problems are inevitable. In the long run, this will promote the longer-term and more stable development of the entire offshore wind power industry. The key is to solve problems in development, but not because of some small problems in the development process.
Offshore wind power is difficult to stop. 2020 plans 22.8 million
According to the statistical report of BTM Consulting, as of the end of 2010, the global installed capacity of offshore wind power was 3.554 million kilowatts, mostly in Europe. In 2010, the number of new offshore wind turbines in the world was 1.44 million kilowatts, more than double that of 2009, and the installed capacity of offshore wind power in Europe increased by nearly 50%. It is estimated that the installed capacity of offshore wind power will reach 1.4 million kilowatts this year. By 2015, the installed capacity of offshore wind power in the world will reach 26 million kilowatts.
China has a long coastline. The preliminary results of the China Meteorological Administration's wind energy resources show that the installed capacity of wind power of 5-25 meters in China and 50 meters in China's sea area is about 200 million kilowatts; 5-50 meters water depth and 70 meters height wind power can be installed. The capacity is about 500 million kilowatts.
China's offshore wind power installed capacity in 2010 is the sixth in the world, 106MW, accounting for 3.1% of the world, far below our onshore wind power installed capacity. The UK is the leader of offshore wind power, accounting for about half of the world's installed capacity. According to the preliminary objectives of the provinces that have completed the planning, Shanghai, Jiangsu, Zhejiang, Shandong, Fujian and other provinces installed about 10.1 million kilowatts of offshore wind power in 2015, including 5.9 million kilowatts of offshore wind power and 4.2 million kilowatts of intertidal wind power; The installed capacity is 22.8 million kilowatts, including 17.7 million kilowatts offshore and 5.1 million kilowatts in the intertidal zone. Other provinces are pending targets of 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, which has been proved by the development of the global wind power market. With the further development of offshore wind power resources and the continuous improvement of technology, the future of offshore wind power industry will surely become a new direction for the development of the global wind power industry.
China and Europe have their own strengths.
The development of offshore wind power in Europe is of reference to China, but not all experiences are worthy of China's follow-up.
The situation in Europe is very different from that in China. Europe is not cold in winter and not hot in summer. Their design temperature is minus 25 degrees Celsius, which is not enough in China. China has many types of winds with three types and four types of wind speeds. When Huarui Wind Power Co., Ltd. cooperated with Huaneng New Energy, the blades of 1.5 MW models were generally 67 meters to 70 meters, while Sinovel launched 82 meters of blades. Increase the sweeping surface and increase the utilization rate, which is more in line with China's wind resource conditions.
Regardless of whether it is for Chinese companies or European companies, in the process of exploring the international market, in terms of technology and price, it must be developed locally. For Chinese companies, only in the concept of equipment first, can this industry be truly independent. Developed.
The rapid development of China's offshore wind power in recent years has also proved this point. In 2010, 34 3MW offshore wind turbines independently developed by Sinovel Wind Power Co., Ltd. were the first offshore wind farms outside Europe except Europe, and China's first national offshore wind power demonstration project – Shanghai Donghai Bridge offshore wind farms all connected Power generation, and successfully passed 240 hours of 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. said: “As the first offshore demonstration project in China, the availability of Huarui Wind Turbine Group averaged over 95%, and the highest reached 97.7%. At present, the unit is running well. The customer service department has rich experience, meticulous maintenance and rapid response. At the same time, after the warranty period, Huarui still has maintenance engineers stationed near the wind farm, while foreign enterprise maintenance engineers are difficult to do."
Longyuan Jiangsu Rudong Intertidal Zone Test Wind Farm has a total of 9 equipment suppliers. Among them, the intertidal 3 MW wind turbine with independent diameter developed by Sinovel Wind Power has an impeller diameter of 113 meters. It is the most advanced intertidal wind turbine in the world. It was connected to the grid on September 15, 2010, and passed the 240-hour assessment on December 13, 2010. The average availability of the unit reached over 95%, and with stable operation, the availability will be further improved.
Guohua Energy Jiangsu Dongtai Wind Power Company Production Department Wang Lin told this reporter: "The Guohua Dongtai Wind Farm has used more than three years of Huarui fans. It has been proved that Huarui Fan's power generation is higher than that of a foreign brand fan. Look, there is no difference in the quality of domestic fans and foreign fans. Moreover, Huarui's after-sales service is better. After the warranty period, Huarui still has maintenance engineers standing near the wind farm, and is on call."
Internal consumption and sales are all in line with national interests.
China's wind power industry has just started. Compared with the long and stable development process in foreign countries, China's wind power industry can be described as rapid, so some problems are relatively normal, but with the maturity of industry technology and the steady development of the industry, the problem will be very It can be solved quickly; Huarui Wind Power has reached the international leading level of operation, whether it is the current 1.5 MW mainstream model on the land or 34 3 MW offshore demonstration projects of the Donghai Bridge.
Recently, among domestic wind power manufacturers, accusations have been heard from time to time, and there is a growing trend. From a good starting point, it is a bitter medicine to promote the development of China's wind power industry; from the actual effect, it has caused the internal consumption of domestic manufacturers, cast a shadow over "Made in China". In the long run, the domestic wind power market will be handed over to the domestic wind power market. The risks of international giants. In today's rapid development of the wind power industry, only wind power upstream and downstream enterprises work together to continuously improve their technical strength, can continue to promote the long-term development of the industry, and enhance the international competitiveness of China's wind power industry.
Internal friction will cause the wind power market to succumb to foreign countries to improve technical strength is imminent
