鉴于太阳能资源的测量和评价是太阳能开发利用的重要基础,按照光伏电池两种主要安装方式(倾斜固定和太阳跟踪),利用单晶、多晶和非晶三种典型的光伏组件设计进行了太阳能光伏资源观测试验,获得了各季节典型晴天条件下各类型光伏组件辐照度的日变化特征和倾斜面光伏组件一年中月均每日可发电量的极大值、极小值及其月份。通过对比各类型光伏组件在太阳跟踪器上和纬度倾斜面上光伏辐照度变化,得出跟踪光伏组件日均光伏曝辐量与倾斜光伏组件日均光伏曝辐量的相比较优势。根据光伏组件的观测结果推算出各类型光伏组件的光伏反演辐照度,与气象辐射观测用总辐射表的总辐射辐照度趋势非常一致,在太阳能光伏主要利用时段相对误差基本在10%以内。 相似文献

The aerohydrodynamic and heat exchange characteristics in the cylindrical heat receiver of a solar cylindrical parabolic concentrating module are investigated. The mathematical model is based on the Navier- Stokes equation system for a laminar flow in a channel. The model is implemented using the control volume method. The created computer algorithm allows carrying out parametric studies and revealing the most rational geometric, dynamic, and power parameters of the process. The proposed model describes the general physical outlines of the heat exchange in a cylindrical heat receiver which allows estimating the influence of the environment—wind velocity, ambient temperature, etc.—on it. 相似文献

通过对槽式太阳能集热器结构及能量转换过程特性的研究,建立了基于多热容变物性的集热器动态仿真模型,并由LS-2型槽式集热器实验数据进行了验证.在仿真平台上结合泵、阀门等模型组建起集热系统仿真模型,并根据SEGS-VI的电站实际运行数据进行了对比验证.在此基础上,分析研究了系统的集热效率和所消耗总泵功随太阳辐照量及导热油流速的变化,得到了不同工况下集热系统的最优折合效率、导热油最佳流速和单支路最优长度.结果表明:在相同的导热油进、出口温度下,太阳辐照量越大,集热系统最优折合效率越高,当太阳辐照量从500 W/m2升至1 000W/m2时,导热油最佳流速从2m/s变化到3m/s;在同一太阳辐照量下,系统最优折合效率随导热油工作温度的升高而降低. 相似文献

Renewable energy technologies are in the centre of interest to narrow the gap between fossil fuels and clean energy systems. The dominant role of solar energy systems among the alternatives is beyond question owing to being associated with an infinite energy source, well-documented theory, simplicity, eco-friendly structure and notably higher energy and exergy efficiency range compared to other renewables. However, in solar energy systems, conventional working fluids with poor thermophysical pro... 相似文献

Hydrogen is regarded as a potential future energy carrier. It can be produced by the electrolysis of water with the required power supplied by a photovoltaic module. The hydrogen in this study was produced using a hydrogen generator with a solid polymer electrolyte. The required power was supplied by a photovoltaic module rated at 3.4 V, 27.45 A. The experimental system was designed and constructed so that the photovoltaic module was directly coupled to the hydrogen generator. The system characteristics: quantity of hydrogen produced, current/voltage output characteristics of the PV module, PV module and H2 generator temperatures were measured and analyzed. A method to design a solar hydrogen energy system, providing the most cost effective hydrogen generation, was developed. In this method, the design point is chosen based on the irradiance during system operation under rated capacity. The data supplied by the experimental system clearly showed the importance of considering the ratio of photovoltaic module cost to hydrogen generator cost when designing an optimum solar hydrogen system. 相似文献
