Abstract

A large-scale wind farm usually consists of many wind turbine generators, and the model of such wind farm will be complicated if every wind turbine generator is modeled in detail. Therefore, an equivalent model is necessary to simplify the model and reduce the order of wind farm model. An appropriate grouping method is important for equivalent modeling. In this paper, a grouping method of wind turbine generators based on Fréchet distance is proposed, and the theory of this method is introduced. An example of wind farm is built and wind turbine generators in this wind farm are grouped by this method. The effectiveness of this method is confirmed by the output variables simulation curves of detailed model and equivalent model.
基于栅格距离的风力发电机组分组方法
大型风电场通常由多台风力发电机组组成,如果对每台风力发电机组进行详细建模,将会使风电场的模型变得复杂。因此,需要一个等效模型来简化模型,降低风电场模型的阶数。适当的分组方法对等效建模至关重要。本文提出了一种基于区间距离的风力发电机组分组方法,并介绍了该方法的原理。以某风电场为例,采用该方法对该风电场中的风力发电机组进行了分组。详细模型和等效模型的输出变量仿真曲线验证了该方法的有效性。
