摘要
近年来,我国北方地区风电场的风电机组叶片折断事件时有发生,叶片材料的选择、叶型的优化、叶片的除霜功能等问题引起了业内人员的关注.但从控制系统上看,在结冰情况下,没有采取灵活的功率控制策略也是造成叶片受力过大的一个重要方面.本文通过分析叶片在结冰后的受力变化,提出一种叶片结冰情况下的控制系统优化思路,供有关人员参考.
In recent years, the wind turbine faults of wind farms in northern China have occurred frequently. The selection of blade material, optimization of blade type, and defrosting function of blade have attracted the attention of industry personnel. However, from the perspective of the con trol system,the failure to adopt a flexible power control strategy is also an important aspect that causes the blade to bear too much force. By analyzing the force change of the blade after icing, this paper puts forward an optimal idea of the control system under the condition of icing for refer ence.
