摘要
针对风力机叶片结冰问题,提出了一种基于气热法原理设计的叶片除冰系统。首先对气热除冰系统进行设计,并借助地面试验来分析气热加热系统的可行性,然后通过对已装机运行的风电机组进行现场改造的方式来对气热除冰系统的可靠性进行分析。试验结果表明所设计的气热除冰系统方案可行,对环境温度为-10~0℃范围的叶片除冰效果显著,试验运行稳固可靠无异常。
Based on the principle of gas thermal method,a blade de-icing system is designed to solve the icing problem of wind turbine blades in this paper. First,the design of the gas thermal de-icing system is introduced.Then,the feasibility of the system is studied in the laboratory. Finally,the reliability of the gas thermal system is analyzed by combining the actual situation and experimented with the de-icing system on field test of wind farm. The experimental results show that the design of the system is feasible,the wind turbine gas thermal system is running reliably without exception during the test,and the effect of de-icing is obvious. This system could be applied to deicing of wind turbine blades.
