摘要
现有风力发电设备存在高度低,风能利用有限,尺寸庞大,制造、安装困难,风动机转速低,难以实现对发电机直接驱动的问题。在1 000 m以上的高空,风功率密度可高达10 kW/m2以上。利用高空风力资源将成为风电技术领域的迫切任务,是满足人类对清洁再生能源需求的重要途径。
Traditional wind-power generation equipment exists problems such as limited wind energy utilization rate due to lower equipment installation height,difficult manufacture and installation due to the equipment＇s enormous dimension, low wind turbine rotation and difficulty in realization of generator direct drive.The wind power density can be over 10 kW/m2 in the air at the height of over 1 000 m,so utilization of the high air wind-power resource is a urgent task for wind-power generation industry and is a crucial way to meet people demand on renewable energy.
