中文摘要: 沙漠中建设太阳能电站是有效利用沙漠土地及光照资源、实现能源可持续发展的有效手段之一,而沙尘暴作为沙漠的主要产物又是影响太阳能发电器件的主要因素。解决沙漠沙尘对太阳能发电器件的影响问题,已成为工程界和学术界关心的课题。本项目基于内蒙古中西部地区沙尘环境特征,研究沙尘在风沙两相流中的运动状态及沙尘在太阳能发电器件表面的沉降条件、建立沙尘在太阳能发电器件表面的沉降模型,应用两相流理论及沉降理论分析、基于ANSYS Fluent软件的数值模拟与风洞实验测试相结合的研究方法,研究在不同沙漠环境参数下沙尘在发电器件表面积尘的沉降特点及沉降规律;在模拟沙尘环境下进行沙尘对太阳能发电器件表面冲蚀试验,研究不同沙尘环境下太阳能发电器件表面的积尘条件以及受沙尘的冲蚀磨损机理;在此基础上提出有效方法来解决沙尘对组件输出功率影响问题。研究结果将为沙漠建设太阳能发电站以及太阳能发电器件的设计、应用和防护提供依据。

英文摘要: Building solar power station in the desert is effective utilization of desert land and resources of light, one of the effective methods to realize sustainable development of energy, and dust storms as the main product of the desert is the main factors influencing the solar power devices. the problem that dust effect to solar power devices on desert , has become the influence of engineering and academic circles concerned topic. This project based on dust environment characteristics in the midwest of Inner Mongolia , the dust in the solar power devices surface settlement conditions, set up a dust in the solar power devices surface subsidence model, the application of sedimentation theory analysis, based on the software of ANSYS Fluent numerical simulation and wind tunnel test combination research methods, research in different environmental parameters in desert dust solar power devices surface dust settling characteristics and settlement law; In the simulation under the environment of dust do the solar power devices surface erosion test, to study the dirt retention on the solar powr devices surfaace and the erosion wear mechanism at the different dust environment; Based on this, the effective method to solve the dust of the component output power problems. The results of the study will be a basis for the design and construction and application of desert solar photovoltaic power plant.
