Résumé partiel
Under the background that countries around the world are actively adjusting their energy structure in response to the global energy crisis,in view of the growing development status of desert photovoltaic power plants,the following two aspects of research content are proposed.First,the large-scale establishment of solar photovoltaic power stations in desert areas has a differentiation mechanism for local desert wind-sand movement.Second,photovoltaic modules are erected in the form of arrays and run in a sandy desert environment.When the wind-sand move across the photovoltaic array,the impact on the output performance of the modules at different relative positions is different.This is to discuss the interaction mechanism between the desert climate characteristic product—wind-sand movement and the output performance of each component of the photovoltaic array when photovoltaic power plants are built on a large scale in the desert area.The above-mentioned problems are studied by three research methods : field measurement,numerical simulation and wind tunnel test.(1)Taking the internal wind speed change law of a photovoltaic power station in Kubuqi desert as the test object,the changes of wind speed at three characteristic heights of the photovoltaic array with the two main directions of the array expansion in different monitoring ranges were measured and analyzed.The results show that the laying of photovoltaic arrays has a significant impact on the wind speed near the ground,especially reflected in the upward air movement of the photovoltaic modules in the north-south direction.(2)Based on the field measurement results,a numerical simulation analysis was performed on the distribution of the wind-sand two-phase flow inside the photovoltaic array with the incoming flow direction from the north to the south of the photovoltaic array.
