VPP方法对小尺度风场结构中心区域的反演展现了良好的性能,但在边缘区域,由于风速变化剧烈,破坏了径向风场的连续性,导致反演算法在该区域失效。研究了受干扰的反演区域的识别和定位方法,推导出同一个径向上水平切向风速一致,依此对水平切向风速修正,提出一种改进的VPP反演算法,采用该方法反演模拟的小尺度辐散风场,仿真结果验证了方法的有效性。
The VPP method performs well on the inversion of the small-scale wind farm structure in the central area. However, in the marginal area, the continuity of the radial wind field is destroyed due to the drastic change of the wind speed, leading to the failure of the inversion algorithm in this area. The method of identifying and locating the disturbed inversion region is studied, and the horizontal tangential wind velocity in the same radial direction is deduced. Based on this, the horizontal tangential wind speed is corrected and an improved VPP inversion algorithm is proposed. The simulation of small-scale divergent wind field, the simulation results verify the effectiveness of the method.
