基于发电厂的风力发电机系统优化设计

提出一种基于发电厂的风力发电机设计理念,以风电场年发电量和发电质量作为优化目标,采用伸缩式叶片结构,在低风速下伸展叶片以提高风机输出功率,在高风速下收缩叶片,结合变桨实现输出功率调节;将额定风速、伸展时最大叶片长度、收缩时最小叶片长度和叶片中心半径作为优化变量,建立风机系统优化模型,运用遗传算法获取风机最优设计参数.结合风机设计实例,验证了风机系统优化设计的可行性.

Optimal Design of Wind Energy Conversion System Based on Power Factory

A design method of wind energy conversion system based on the concept of power factor is proposed.The optimal power energy and electricity quality are considered as optimization objects.The blades are extended to improve power out-put at low wind speed and shrunk with regulating mechanism at high wind speed to adjust power out-put.Taking the rated wind speed,the maximal length of an extended blade,the minimal length of a shrunk blade and the central radius of a blade as optimization variables,an optimizatio...
