在潮湿凝冻地区实现风能资源的精细开发有利于我国减污降碳战略实施，抵御风电机组凝冻灾害停运以提升机组发电量是最直接手段。文中针对云贵高原地区某风电场5MW机组和凝冻地理环境，构建了3台主动气热法抗凝冻灾害试验机组并实施现场试验，对比分析机组叶片的防冰过程和解冻过程，探索百米级叶片大型机组主动气热法抗凝冻灾害效果并开展叶片加热系统性能分析。在本试验中发现，5MW机组加热系统的解冻效果显著但在环境温度-2℃以下时叶片防冰效果不理想；机组叶片加热温度控制性能较好，抗凝冻灾害试验综合能耗对同期发电量占比不足8%，试验期间最大发电量提升到50000kWh以上。试验结果表明，在潮湿凝冻地区对百米级叶片大型风电机组实施主动气热法抗凝冻灾害具有技术可行性。

The precise development of wind energy resource in humid and frozen areas is beneficial for the implementation of China"s pollution reduction and carbon reduction strategy，and the direct way is to improve the power generation of these wind turbines by resisting freezing disasters. For 5MW wind turbine and its freezing geographical environment in a wind farm of YunnanGuizhou Plateau, the antifreezing disaster systems of three 5MW wind turbines with the active aerothermal method were constructed and their tests were carried out. The antiicing process and thawing process of the turbine blades were compared and analyzed, and the antifreezing effect was explored to this active aerothermal method for the large-scale wind turbine with 100m length meter blades when the performance analysis of the blade heating system was carried out. In this test, the thawing effect of the heating system of the 5MW wind turbine was significant but its antiicing? failed when the ambient temperature was below -2 ℃, and the heating temperature control performance was better, and its comprehensive energy consumption accounted for less than 8% while the maximum power generation was increased to over 50000kWh. This test results indicate that it is technically feasible to implement the active aerothermal method to untifreezing disasters on the large-scale wind turbine with 100m grade blade in humid and frozen areas.
