Loss of standards as the biggest bottleneck in wind power development

Li Ye, Director of the Energy Conservation and Technology Equipment Division of the National Energy Administration officially announced the “Technical Specifications for Large-scale Wind Farm Grid-connected Designs” with “a long-standing process”; this is the same as the wind power technical standard that is most concerned about. There are 18 wind power national standards released on August 5, involving a number of standards that are currently urgently needed for the development of wind power industry, such as large-scale wind farm on-grid connection, offshore wind power construction, wind turbine condition monitoring, wind farm power quality, and wind power critical equipment manufacturing requirements. . At this point, among the 298 standards for wind power standards that were originally planned to be released before the end of this year, 75 have been issued, accounting for only 1/4 of the total. This is what the reporter learned from the second session of the second session of the Energy Industry Wind Power Standards Technical Committee held in Beijing and the wind industry standardization work conference in the energy industry.

Liu Qi, deputy director of the National Energy Administration in charge of new energy, pointed out that with the rapid development of China's wind power industry in recent years, there has been heavy construction, heavy scale, light weight, and light management problems, which are closely related to the relative lag in wind power standard construction. Wind power development lacks standards for wind turbine manufacturing and quality assurance systems, and lacks installation and operation, maintenance management, and technical standards for real-time detection and fault diagnosis that are compatible with national conditions. Corresponding to his speech, the reporter was informed that since the beginning of this year, four major wind power off-grid accidents have occurred in China. The experts in the industry have studied the reasons, "There are problems with the lack of standards in all aspects of industrial development."

Liu Qi emphasized that China must transform from a large wind power country to a powerful one. Future industry development must change from the pursuit of speed to the pursuit of quality, from the pursuit of installed capacity to the pursuit of wind power generation, from centralized large-scale development to large-scale development and decentralized development. From land-based wind power to land-based and offshore wind power development. This requires standardization work to keep up with the pace of industrial adjustment and establish an advanced wind power standard system. He defined the "advanced wind power standard system" is to fully consider the advanced technology of wind power installation, grid connection and consumption in the technical indicators, fully consider the advanced technology of wind farm design, construction and operation, and fully consider advanced manufacturing of key wind power equipment. Technology, unified in the connotation and layout of the system and in line with China's national conditions, to meet the needs of domestic and foreign markets, with the international full integration.

In view of the extremely heavy task of perfecting and revising wind power technical standards by the end of the year, Liu Qi stated that the National Energy Administration will organize efforts to increase the implementation of major standards, revise and publish, further improve the quality standards of wind turbines and establish corresponding inspection and certification systems. At the same time, strengthen international standardization exchanges and cooperation.
