Wind power industry technical standards show high profit

Editor's note: Wind power and high-speed rail, the two national strategic development projects worth hundreds of billions of dollars in the market, have all exposed safety issues due to rapid development. Recently, the relevant management departments reinforced 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 raises anxiety

The rapid development of wind power has made the 2007 national promulgation of a long-term goal of 30 million kilowatts by 2020. 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

The Jiuquan wind power accident in February this year seems 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, in the process of rapid development of wind power, it has always been accompanied by quality concerns. For example, on January 5 this year, Sinovel was replaced during the installation and commissioning of fans at the construction site of Chahar Wind Power Co., Ltd., Shangyi County, Hebei Province. When the fan wind instrument shelf was touched, 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 made the accident blower

The improvement of wind power quality requires good work in both management and technology. In particular, wind power should be managed throughout the entire life cycle. China must correctly handle the relationship between quality and cost.

- He Dexin, Vice Chairman of China Renewable Energy Society

It is worth noting that the investigation of related departments found that the lack of “low-voltage ride-through capability” of wind turbines and the lag in power 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.
