摘要
每年冬季我国南方的山地风电场频繁出现风机叶片覆冰现象,造成风电场发电功率损失,影响电力系统运行的安全稳定。覆冰情况与当地气候条件密切相关,本文利用统计方法挖掘数值天气预报中与覆冰相关的重要影响因素,并通过假设检验得出结论:随着时间和空间的变化,气象要素对风机叶片覆冰情况的影响程度会发生改变。基于本文的研究结论可以更加准确把握风电场覆冰规律,并根据天气预报对风机叶片覆冰情况进行提前判断,从而指导生产运营,为风力发电的安全与效率提供有力保障。
Every winter in mountain wind farms in southern China,fan blades are frequently covered with ice,resulting in power loss of wind farms and affecting the safety and stability of power system operation.The icing situation is closely related to local climate conditions.In this paper,statistical methods are used to explore the important influencing factors related to icing in numerical weather forecast,and through hypothesis testing,it is concluded that with the change of time and space,the degree of influence of meteorological factors on the icing situation of fan blades will change.Based on the research conclusions of this paper,the icing law of wind farm can be more accurately grasped,and the icing situation of fan blades can be judged in advance according to the weather forecast,so as to guide the production and operation and provide a strong guarantee for the safety and efficiency of wind power generation.
