摘　　要：风参数是风电机组设计中最重要的外部环境参数,其取值直接影响风模型的准确性,进而影响风电机组的设计成本及其在现场环境中的适应性。为了使中国风电行业从业者了解风电机组设计标准中风模型的演变过程,在风电机组设计开发、适应性评估等各个阶段选用更为合适的风模型及其参数,重点介绍了正常湍流模型(NTM)、极端湍流模型(ETM)、极端运行阵风(EOG)模型、方向变化的极端相干阵风(ECD)模型、极端风剪切(EWS)模型等风模型的修订背景、修订方法及其影响。虽然IEC 61400-1系列标准中的风模型根据行业应用经验在不断演变,但随着风电机组大型化发展趋势,风模型的真实代表性仍面临巨大挑战,尤其是50年重现期的极端工况下的风模型,很难通过实测数据验证,其在不同现场的代表性和合理性值得进一步探究。Wind parameters are the most important external environmental parameters in the design of wind turbines,and their values directly affects the accuracy of the wind model,which in turn affects the design cost of wind turbines and their adaptability in the on-site environment.In order to enable practitioners in the Chinese wind power industry to understand the evolution process of wind models in wind turbine design standards,and to select more suitable wind models and their parameters in various stages such as wind turbine design and development,adaptability evaluation,etc.,this paper focuses on the revision background,revision methods,and impacts of wind models such as NTM,ETM,EOG model,ECD model,and EWS model.Although the wind models in the IEC 61400-1 series standards are constantly evolving based on industry application experience,with the trend of large-scale wind turbine development,the true representativeness of wind models still faces huge challenges,especially for wind models under extreme operating conditions with a 50 year return period,which are difficult to verify through measured data,and its representativeness and rationality in different sites are worth further exploration.
