风光同场条件下阴影避让问题分析

Analysis of Shadow Avoidance Under Fans and Pv Was Constructed in the Same Field Conditions

在风光同场条件下,通过PVsyst仿真模拟,分析了在风机阴影区域内不同位置的发电量下降比例。为了更具代表性,选取了敦煌、呼和浩特、盱眙三个地区作为仿真项目所在地,三个地区风光资源均较好,其中敦煌的辐照资源最佳,呼和浩特其次,盱眙相对一般。在PVsyst内通过创建风机模型,在相同条件下分析了不同阴影区域内的发电量影响。通过电量的分析发现,在轮毂高度1倍阴影以内由于阴影影响电量下降比例均超过1%。当距离超过1倍轮毂高度时电量下降比例迅速下降,考虑到风机倒塔的影响建议在风机阴影范围里1.5倍轮毂高度区域内不进行光伏组件的排布。

under fans and pv was constructed in the same field conditions,PVsyst simulation was used to analyze the proportion of PV power generation declined at different locations in the shade area of the wind turbine.In order to be more representative,Dunhuang,Hohhot and Xuyi were selected as the project location.Dunhuang Solar energy resources is best in three locations,Hohhot is sceond and Xuyi was worst.The wind turbine model was created in,PVsyst simulation to analyze the impact of power generation in different shaded areas.Through the analysis of power generation,it is found that within 1 time of the hub height area,the proportion of power generation decline is more than 1%.When the distance exceeds 1 time of the hub height,the proportion of generation decline speed drops quickly.Furthermore,considering the impact of the wind turbine collapse,1.5 times of the hub height is necessary.
