It is reported that the UL organization initiated the establishment of a global wind turbine related stakeholders to participate in the wind turbine life extension standard preparation working group, ANSI/UL 4143 standard has been approved by the US National Standardization Committee ANSI in February this year, becoming the world's first national wind turbine life extension standard
.
The design life of wind turbines is required to be at least 20 years
in accordance with GB/T18451.
1/IEC61400-1 standards.
At present, some units are at or near the design life, and it is necessary to determine the life loss and remaining usable life (RUL)
of the whole machine or main components.
The rapid growth in installed capacity of wind power in the past few years means that it is likely that in the near future, more wind turbines will eventually approach or reach the end
of their design life.
Wind turbine structures are designed to have a fatigue life
of 20 years under normal wind resources and operating conditions according to design standards and specifications.
Generally, the actual wind conditions such as air density and turbulence intensity are different from the standard design conditions, and the design may be more conservative
.
Therefore, after 20 years of operation, it is possible that the structure of the wind turbine will not be completely exhausted, but may have a longer life, and its remaining life and value
need to be judged.
Each unit model and technology has different sensitivities under different boundary conditions, so different methods should be used to determine the life of each component, such as remaining useful life (RUL) and extended life
.
Whether to adopt a wind turbine life extension strategy requires careful analysis from many aspects such as technology, project economics and financial risks to ensure that the return on investment of wind power owners is maximized
