The past 2010 is a milestone in the development of renewable energy in China - China has become the world's largest consumer and producer of wind power equipment. “Under the backdrop of rapid economic growth and increasing demand for electricity, the rapid development of wind power plays an irreplaceable role in China’s response to challenges such as diversification of energy structures, environmental protection, and energy conservation and emission reduction.†China Resources Comprehensive Utilization Association Li Junfeng, secretary general of the Renewable Energy Professional Committee, said: "Wind power has become a bright spot in China's economic development and has the potential to dominate the world market."
Sitting on the world's first spot, Chinese wind power only spent 5 years. The vocabulary of “wind and electricity†is all plain and plain in front of “China’s wind speedâ€. China has not only been promoted to the world’s fastest growing installed capacity, it has also created two of the world’s top five wind turbine manufacturers.
After an unparalleled "Chinese wind speed", China's wind power has begun to show its hidden dangers - China's power grid capacity has failed to keep up with wind speed, high-quality wind farm resources have almost been mined, China's wind turbine quality problems surfaced, offshore wind power A new round of "Circular Movement" and so on. In 2010, the Chinese wind power keyword has been unable to be absorbed by a simple “Chinese speedâ€.
"Old Trouble" and "New Injury"
China's power grid with insufficient capacity appears to be particularly weak in the face of the “overflow theory†of wind power. The large-scale "disposal of wind" incident on the grid has hidden the halo of high-speed growth of wind power. As early as in 2009, "overcapacity" became the key word for wind power development, and low-level redundant construction once made wind power industry one of the key regulatory areas of the State Council to prevent overcapacity.
Regarding the view of the "overcapacity" theory, many viewpoints have been confronted so far. The generally accepted view in the industry is that in all aspects of the wind power industry chain, only the production of wind turbine equipment is experiencing overcapacity. In other sectors, especially the entire wind power industry, the investment in wind farms is not high.
The statement made by Li Junfeng in an interview with this reporter was even more direct: "The excess capacity of wind turbines does not exist."
If the theory of "overcapacity" is relatively outdated, the quality problems of China's wind turbines that have repeatedly exploded in 2010 will add "new injuries" to China's wind power.
The first domino accident that took down the annual blower accident was the leader of the domestic thermal power and nuclear power equipment manufacturing industry. Dongfang Steam Turbine Co., Ltd. (hereinafter referred to as Dongqi) ranks third among the domestic wind turbine manufacturers. On January 24, 2010, an Dongfeng Fan of Ningxia Net China Shenzhou Wind Power Co., Ltd. collapsed and was considered as the first wind turbine accident in 2010. Since then, many fan quality incidents have caused domestic wind turbine manufacturing faucets to be involved in a mass vortex. The top five of the domestic machine manufacturing were almost completely spared.
In addition to serious downtime and fire accidents, the frequent occurrence of fan blade and spindle breakage, motor ignition, gear box damage, control failure, and the speed of flying cars are plaguing Chinese wind power owners.
Hua Gang, vice president of Huarui, explained that the former Huarui fan was in a down event at the Jiuquan wind farm. The main reason was that “when the power supply was installed improperly before power on, it had nothing to do with the wind turbine itselfâ€.
"Accidents are the coupling of many factors and it is difficult to identify them as a single cause." Li Junfeng said that several of the collapse accidents in 2010 were not due to the quality problems of domestically produced fans, but were due to improper operation in the construction process. “Quality incidents are only normal in the development of the wind power industry. All kinds of situations in the wind power industry are within reasonable limits,†said Li Junfeng.
The emergence of fan quality issues is inevitable in the development of the wind power industry. According to the practice of European countries and the United States, each wind turbine must be debugged one by one to be connected to the grid, and this process usually takes one to two years. In China, the large-scale installation of wind turbines in the first two years has skipped a long period of wind measurement debugging. In 2010, it started to cause problems.
Inadequate technology If it is said that the quality problem of China's wind turbines is a combination of many factors, it is difficult to say that the quality of domestically produced wind turbines is too low. The key technology behind this is the “root cause†of wind power in China.
The weak foundation of R&D allows the copying of foreign technical drawings to constitute almost the entire industry status of wind power in China.
For a long time, China has only paid attention to the increase in installed capacity and the upgrading of wind turbines. International wind power pioneers are more concerned about the cost of electricity. “We always believe that the reliable operation of wind turbines and the effective reduction of the cost of electricity during the 20-year lifecycle of wind turbines are the key to helping customers achieve profitability.†Vestas, the world's largest wind turbine manufacturer, ranks fourth in the Chinese market. ) President Tang Mahler said.
The cost of electricity refers to the cost of a wind turbine in its life cycle (usually 20 years), integrated manufacturing, power generation, and maintenance, and the cost of allocating electricity to one degree of electricity.
"We believe that the cost based on the life cycle can represent the true cost of the wind turbine," said Tangle. Here, there is a big gap between the "technical content" of China's wind turbines and that of foreign-invested wind turbines.
However, for a long time in the past, such a concept was hardly accepted by Chinese customers. "Vestas's products are really good things, but if the price can be low, it will be even better." This almost represents the true mentality of most wind power owners. It is under such universal recognition that Chinese wind turbines have rapidly opened up their lands with their relatively low prices and relatively outstanding cost-performance advantages, and they have occupied a large scale in domestic wind farms.
However, this advantage of making wind turbines in China is losing. In 2010, after China entered the world’s second largest installed market for wind turbines, the oversupply of the Chinese wind energy market and the slowdown in the growth of new installed capacity were evident. The Chinese wind energy market or began to bid farewell to the pure scale of the era of kings, and the owners of electric powers began to examine the actual operating costs of quality, technology and electric field. Although China's wind turbines are about 20% cheaper than foreign-made wind turbines, frequent “small problems†and high maintenance costs have gradually allowed owners to rewrite their orders.
For Chinese wind turbine manufacturers, they have quickly gained market share by buying foreign technical drawings and low manufacturing costs in the first round of development in the past five years, but in the second round of wind power development where the growth rate has slowed down. The disadvantage of congenitally deficient technology has begun to appear gradually.
Sitting on the world's first spot, Chinese wind power only spent 5 years. The vocabulary of “wind and electricity†is all plain and plain in front of “China’s wind speedâ€.
