Wind power and high-speed rail, the two national strategic development projects worth hundreds of billions of dollars, have all exposed safety issues due to rapid development. Recently, the relevant management departments have strengthened the “safety valve” in different forms. The development of the two strategic industries has been guided by the government’s “visible hand” from the outset. When problems arise during development, the government has no turning back and acts as the “night watchman” of the market. This can not help but remind us of a myth in economics: Who should ride the main driving position in the cab of an economy train?

The installed capacity has doubled for five consecutive years, with a cumulative installed capacity of 44,733.29 MW. The installed capacity of wind power is the largest in the world. This is the result of the rapid development of China's wind power industry in the past few years. The overcapacity, difficulties in grid connection and frequent quality problems are also the pain behind the development of the leap-forward wind power industry. The Chinese wind power industry, which has been eager to catch up, may have to stop and summarize. Industry insiders expect that the wind power industry will enter the rectification period and it is expected that 80% of the companies will be eliminated.

Acceleration has caused turbulence in the rapid development of wind power, making the long-term goal of 30 million kilowatts issued by the state in 2020, and it will be out of place just two years later, because next year, the development of domestic wind power may break through this goal.

Li Junfeng, deputy director of the Energy Research Institute of the National Development and Reform Commission, said that the Jiuquan wind power accident in February this year seemed to have caused the government to set down its determination to rectify the wind power industry. On May 9th, the National Energy Administration issued the “Notice on Requirements for the Construction of Jiuquan Wind Power Base”, which made severe criticisms to the Energy Bureau of Jiuquan City and emphasized that “projects that have not been approved by the state may not start construction”. This is also the second notice issued by the National Energy Administration on Jiuquan wind power construction after March 27th.

On February 24, the three-phase short-circuit fault of the 35 kV cable feeder cable head of Gansu Jiuquan Wind Power Base in Gansu Province caused the loss of power to 598 wind turbines and caused a loss of power of 840,000 kilowatts. This is also the last few years in China. Wind power frequently shows a microcosm of the accident.

In fact, during the rapid development of wind power, it has always been accompanied by quality concerns. For example, on January 5 this year, Sinovel Wind Power Co., Ltd. installed the turbine at the construction site of Chahar Wind Power Co., Ltd., Shangyi County, Hebei Province. During the process of replacing the fan wind instrument shelf, a 35 kV high voltage line was touched and an electric shock occurred, killing 3 people.

Industry insiders believe that frequent accidents expose many potential problems in China's wind farms. For example, in the construction of wind farms, the project quality management of some project owners is not strict, construction quality management of construction units and supervision and management of construction quality by supervision units are not in place; grassroots grid companies have lax access to wind farms, and unauthorized permission is not passed. Wind farms connected with grid safety assessment are connected to the power grid; in terms of wind farm operation, reactive power management and secondary system management do not meet grid security requirements.

Who created the accident? The improvement of wind power quality requires good work in both management and technology, and in particular, the management of wind power in the entire life cycle. China must correctly handle the relationship between quality and cost.

He Dexin, deputy director of the China Renewable Energy Society, is worth noting that related department investigations have found that the lack of “low-voltage ride-through capability” for wind turbines and the delay in grid development relative to new energy development are the main causes of accidents.

“Insufficient R&D investment has led to backward technology, overcapacity of equipment, heavy speed and quality, and difficulties in grid connection, which are both problems in the development of wind power in China and the source of frequent quality problems.” Lin Boqiang, director of the China Energy Economic Research Center, Xiamen University, accepts An interview with the International Finance News said that it is time for the industry to stop and rectify.

As Lin Boqiang said, the wind power industry may soon usher in a wave of consolidation. According to the news, the National Energy Administration's five organizations including the China Electric Power Enterprise Association have formulated the "Framework for Wind Power Standards (Discussion Draft)", and the "Wind Power Equipment" jointly researched and drafted by the State Ministry of Industry and Information Technology and the National Development and Reform Commission and the National Energy Administration. The manufacturing industry access standards have also entered the consultation stage and will be announced soon.

At the same time, in the face of no room for internal consumption and no external channels, China’s Inner Mongolia Autonomous Region Development and Reform Commission issued the “Notification on Promoting Integration and Restructuring of Wind Power Enterprises in the Region and Reducing the Guidance Opinions of the Main Body” in the largest province of wind power resources in China. Through the merger and reorganization, the wind power enterprises in the region will be controlled within 25. "Being the first province to implement total development control of wind power development companies.

Lin Boqiang believes that the introduction of new standards will further reduce the living space of small enterprises. In the next few years, it will not be ruled out that more than 80% of wind power equipment companies will disappear through restructuring and mergers.

Policy push turns?

Can not rush forward again, must stop and think! I was a person who had experienced steelmaking times. We could not allow wind power, nor could we let the wind turbines make the "Great Leap Forward."

China Academy of Engineering academician Ni Weidou “Local investment in wind power is somewhat blind. Because construction is too fast, it will intensify the contradiction between excess installed capacity and lack of access to the Internet in the future. In the future, wind power standards will be issued and the target will remain focused on large-scale construction. The introduction of new standards is increasing. At the same time as industry entry barriers, the most important thing is to realize the scale and intensive development of the wind power industry, and to achieve effective interconnection with the power grid.” Song Liang, analyst at the China Central Business Center for Circulation Productivity, said that the government should increase Focusing on the inspection of the entry point and reducing the approval of medium and small-scale wind power, the most important thing is to improve the technical level of this industry, pay attention to technical input, and pay attention to quality.

In addition, Song Liang believes that the most critical thing now is to solve the grid connection problem. “The wind power industry is a systemic industry. It not only installs power, but also includes supporting grid-connected power. The entire industry needs to be developed gradually. The supporting power grid cannot keep up, and the installed capacity is too large, causing waste of resources and investment losses.”

In this regard, Lin Boqiang believes that it is expected that relevant departments will pay more attention to grid connection issues during the next rectification process, and some related measures will be issued in a centralized manner.

The White Paper on the Promotion of Wind Power Development issued by the State Grid recently said that by strengthening the construction of cross-regional power grids and constructing the “Three Chinas” power grid, the nation’s capacity for absorbing wind power can be greatly increased. It is expected that by 2015, the scale of wind power consumption in China will exceed 9,000. With 10,000 kilowatts, it will reach 150 million kilowatts or more by 2020. “Big wind power is integrated into the large power grid” is an inevitable choice for China’s large-scale development of wind power.

Domestic wind power accident In January 2010, the fan of the Datang Zuoyun project collapsed. In January 2010, the Dongfeng Huaneng Baolongshan wind farm fan was burnt. In April 2010, the Inner Mongolia Bayin Siler wind farm unit caught fire. July 2010 Dandong Ocean Red Wind Farm No. 8 fan failure In August 2010, the wind turbine group under construction in Guazhou, Gansu collapsed.
