摘要
目前国内关于隧道洞口光伏发电系统的研究主要是针对隧道场景的工程应用和发电功率预测,针对隧道特有的"白洞"和"黑洞"工况下的光伏组件容量与照明负载匹配问题的研究较少.针对用于照明负载的隧道洞口光伏发电系统应用场景,以晶科能源控股有限公司Tiger Pro系列555 W的8块光伏组件串联构成光伏发电源,以BOOST变换器作为直流变换器,仿真研究在光照、温度、负载变化情况下隧道洞口光伏组件和直流变换器输出端的特性变化情况.仿真结果表明:本研究的串联光伏发电源的输出可在稳态和瞬态情况下满足隧道内照明要求;当辐照降低或负载过载时,可通过额外补充电容或储能系统进行容量支撑.研究结果可为匹配光伏组件数量、照明负载功率提供参考,为支撑隧道照明供电的设计方法提供理论支持和技术指导.
Abstract
At present,the research and practice of photovoltaic power generation systems at tunnel entrances in China are more focused on engineering applications and power generation prediction research for tunnel scenarios.There are few studies on the matching problem of photovoltaic module capacity and lighting load under the"white hole"and"black hole"working conditions unique to tunnels.For the application scenario of photovoltaic power generation systems at tunnel entrances for lighting loads,eight 555 W photovoltaic modules of the Tiger Pro series of Jinko Solar Co.,Ltd.are connected in series to form a photovoltaic power generation source.The BOOST converter is used as a DC converter to simulate the changes in the output characteristics of the photovoltaic modules and DC converters at the tunnel entrance under changes in light,temperature,and load.The simulation results show that the output of the proposed photovoltaic power generation source in series can meet the lighting requirements in the tunnel under steady-state and transient conditions.When the irradiation is reduced or the load is overloaded,additional capacitors or energy storage systems can be used for capacity support.The research results can provide a reference for matching the number of photovoltaic modules and the power of lighting loads,and provide theoretical support and technical guidance for the design method of supporting tunnel lighting power supply.
