摘要:

为促进新形势下冬季覆冰区域风电机组的安全运营和安全管理,分析风电机组落冰安全风险、设备运行风险、电力供应风险是最为严重的叶片覆冰风险。基于这些风险,提出叶片覆冰厚度监测法与机组运行数据监测法相结合的综合覆冰监测方法和风电机组安全运行分级。阐述国内首例大型在役风电机组复合涂层防冰技术方案设计与施工工艺。结果表明:复合涂层防冰技术方案可有效解决风电机组覆冰问题,可为类似工程项目提供参考。

Abstract:

In order to promote the safe operation and safety management of wind turbines in icing areas during winter under the new situation, the safety risk of wind turbine falling ice, equipment operation risk, and power supply risk were analyzed, and they are the most serious risks of blade icing. Based on these risks, a comprehensive ice monitoring method based on the combination of blade ice thickness monitoring method and wind turbine operation data monitoring method was proposed, and the safe operation of the wind turbine was classified. This article elaborated on the design and construction process of the first composite coating anti-icing technology scheme for large-scale in-service wind turbines in China. The results indicate that the composite coating anti-icing technology solution can effectively solve the problem of wind turbine icing and can provide a reference for similar engineering projects.

Key words: wind turbine, blades, icing, monitoring, anti-icing technology
