摘要:

沙漠地区大规模光伏开发会显著改变局地风场与风沙活动,但其内部不同部位的风沙环境分异及调控机制尚不明确。本研究以腾格里沙漠东缘单基柱支撑、板下净空高度为150 cm的典型光伏阵列为研究对象,采用野外同步观测方法,对板前、板后、板间及旷野对照区(CK)在3种来流风速下的近地层风速廓线、输沙率垂向分布、风沙流结构和阻沙率进行了对比分析。结果表明:(1)光伏阵列显著削弱了近地层风速,防风效应具有明显空间异质性,主要集中在50~100 cm高度,其中板后减速作用最强,防风效果最大可达44.47%;板前20 cm高度防风效果在6.79%~7.63%,在400 cm高度可达19.15%~20.93%。(2)光伏板整体降低了风沙输移强度,但内部输沙格局稳定分异,总输沙率板间最高,板后次之,板前最低;阻沙率板前为45.26%~51.93%,板后为26.68%~33.19%,板间为11.95%~19.10%。(3)光伏板未改变风沙流近地表集中的基本规律,各位置高度输沙量均表现为2~10 cm>0~2 cm>10~20 cm,且板间区域的风沙流结构特征值在高风速下甚至超过CK,板下气流通道强化了沙粒的垂向输移能力。荒漠区光伏阵列防沙应采取分区配置策略,板间区域宜作为重点防护单元,板前可维持其减沙优势,板后则需关注基柱周边局地冲蚀风险。该研究可为荒漠区光伏电站分区防沙设计和精细化运维提供科学依据。

Abstract:

Large-scale photovoltaic (PV) development in desert regions can significantly alter local wind fields and aeolian activity, yet the spatial differentiation of wind-sand environments and their regulatory mechanisms within different parts of PV arrays remain insufficiently understood. In this study, a typical single-column PV array with a ground clearance height of 150 cm on the eastern margin of the Tengger Desert was selected as the study object. Based on synchronous field observations, we comparatively analyzed near-surface wind speed profiles, the vertical distribution of sediment transport rates, sand-flow structure, and sand-blocking rates at the panel front, panel rear, inter-panel space, and an open control site (CK) under three incoming wind-speed conditions. The results showed that: (1) The PV array significantly reduced near-surface wind speed, and the wind-reduction effect exhibited clear spatial heterogeneity, mainly concentrated within the 50-100 cm height range. The strongest deceleration occurred at the panel rear, where the maximum wind-reduction effect reached 44.47%, while the wind-reduction effect at 20 cm in front of the panel was relatively weak, ranging from 6.79% to 7.63%, and 19.15%-20.93% at 400 cm height. (2) The PV panel as a whole reduced aeolian sediment transport intensity, but the internal transport pattern remained stably differentiated, with total sediment transport ranked as inter-panel space > panel rear > panel front. The sand-blocking rate was 45.26%-51.93% at the panel front, 26.68%-33.19% at the panel rear, and 11.95%-19.10% in the inter-panel space. (3) The PV panel did not alter the basic law that aeolian sediment transport is concentrated near the ground surface. At all positions, sediment transport at different heights followed the order 2-10 cm>0-2 cm>10-20 cm, and the sand-flow structural parameter in the inter-panel space even exceeded that of CK under high wind-speed conditions, indicating that the airflow passage beneath the panel enhanced the vertical transport capacity of sand particles. The results suggest that sand-control measures in desert PV arrays should adopt a zonal configuration strategy, with the inter-panel space treated as the key protection unit, the panel front maintaining its sediment-reduction advantage, and the panel rear requiring attention to local erosion risk around the supporting columns. This study provides a scientific basis for zoned sand-control design and refined operation and maintenance of PV power plants in desert regions.
