摘要:
风剪切效应会使风力发电机组中各环节的状态发生变化,进而影响最终并网电能的质量。为了对风剪切效应下所受影响环节进行分析,文章以直驱永磁同步风力发电机组隐极式发电机为例,从风轮角度逐一分析由风剪切效应所造成纹波由风力发电机组机械侧传播至电磁侧的过程以及各环节扰动间的关系。分析结果表明,风剪切效应在风轮叶片、发电机转速及塔架等环节中均产生了不良影响,若不加以抑制,还会影响发电机组的并网电能质量。
Abstract:
Wind shear will change the state of wind turbine, and influence the quality of the power feeding back to the network. In this paper, a permanent-magnet direct-drive synchronous cylindrical wind turbine was used as an example in order to study the influence of wind shear. The ripples caused by wind shear in different parts of the generator system, the propagation mechanism, and connections between the ripples were analyzed. The results of the analysis turn out that the ripples caused by wind shear will affect the blades and tower of the wind turbine, change turbine’s rotate speed, even lead to poor power quality.
