摘要
当我们决定要投资风力设备时,首先要获得当地风资源的数据,这风资源最好是几年的平均值,在一般的情况下,当地政府都会保存这数据,但不应包括随机的台风情况,因为风力机在台风的特殊情况下,为保护风力机的结构,都用风力机中的煞车系统将它锁住,不运转.根据这风资源的数据,我们就可以估算出所需风力机与配套发电机的最佳设计。这篇文章包括:①如何决定当地的风速、风功率及风能量:②如何计算所需发电机的功率;③选择控制发电量的考虑,虽然年风能的产值愈高愈好,但系统的复杂性也不容忽视;④如何决定风力机的设立高度与风力机之间的距离.
Before we decide to invest in the wind power equipment, we should collect detailed information about the local wind distribution. This information, excludes the severe weather situations which the windmill will be locked out to prevent any damages, can be used to size up the optimized windmill and the corresponding generator. This article is intended to explain:①how to assess the wind speed and the corresponding wind power; ②how to size up the power of windmill's generator; ③how to pick the control scheme of windmill's power, although the more power it generates, the better, we cannot ignore the complexity of the system;④how to determine the height and space among the installed windmills.
