风电机组叶片防冰技术

Anti-Icing Techniques for Wind Turbine Blades： Critical Review

风电机组叶片结冰会严重影响机组的运行性能产生功率损失、机械故障等一系列问题，防冰技术的应用可以有效避免结冰对机组造成的影响,保证现场作业人员的人身安全。本论文详细介绍了覆冰对机组的影响、结冰的等级划分、对结冰的物理形式及条件,给合叶片表面覆冰的形成原理主要比较了市场上已有的、处于研发阶段的及只在文献中描述过的防冰技术,并对每种方法的优缺点以及在实施过程中的可行性做了探讨分析。

Wind turbine icing will seriously affect the operating performance of the unit, bring the power loss, mechanical failure, such as a series of questions, the application of anti icing technology can effectively avoid the icing on the unit caused the site to ensure the safety of workers. This paper details the impact of ice cover on the unit, grading icing, icing on the physical form and related conditions were introduced, combining the principles of the leaf surface to form a coating of ice, mainly on the market has been compared, in research and development stage and only described in the literature over the anti-icing techniques were discussed and the advantages and disadvantages of each method and the feasibility of the implementation process of analysis.
